Computer Glasses ease eye strain

[ad_1]

headaches, blurred vision and tired eyes after a day working on a computer? It’s an easy answer: Computer glasses

strain on the eyes working on the computer is a real condition, and it even has a name: computer vision syndrome (CVS). Experts say to look at computers simply requires the eyes to work in a way that other activities do not.

Wait, you say. I wear glasses now. And I still get blurred, tired eyes.

There are reasons for that. Ergonomic experts – the people who measure how the body works project – note that the computer screens sit 20 to 26 inches from your eyes. Eye doctor calls this range intermediate vision area -. Covering the distance vision (as when you run), but farther away than reading (your “close” Vision)

Without computer glasses, people often lean forward or backward to improve the visual range. So you get to the end of the day not only with the symptoms of CVS, you get sore shoulders, with back pain or sore throats as well!

Most people under the age of 40 who wear glasses get them to correct their distance vision. Those of us over age 40 often get glasses to correct presbyopia beginning condition -. Loss of focus on the ability which is normal as we age

The problem is, eyeglasses made to correct either of these conditions don ‘t tackle what is happening in the intermediate vision – that space between you and your computer screen! Even bifocals, trifocals and progressive lenses are not made for the PC range vision.

Recent studies have supported the use of computer glasses. The University of Alabama School of Optometry studied vision computer users ages 19 to 30. Participants were randomly selected to be either computer glasses or non-corrective glasses. The researchers found that even when CVS symptoms were not reported employees clearly showed productivity and accuracy.

So you can just take a $ 20 pair of computer glasses at the local office supply store, right? Well, maybe. The advantage of buying the rack is clearly the price, but if you have other problems vision, the single lens glasses might not be the best for you. Experts say the trick to get the $ 20 off-the-rack pair is testing them by reading something that is the same distance from your eyes as the computer screen -. 20 to 26 inches

Glasses from eye doctors come in what is known as “multifocal” style. This can be bifocals, trifocals or progressive lenses of economic activity. The advantage of these more expensive styles is that you will be able to see clearly whether you are looking at the computer, read the notes on the table or winking at that cute co-workers over cubicle from you. The drawback, of course, is that this style requires a visit to the eye doctor and usually cost around $ 300 or more.

Either way, be sure to check out the new glasses by working on your computer. If blurrier not go away, get another pair!

With new technology comes new issues and potential problems. Computers have been around long enough that not only do we have a stable technical difficulties as each computer maker seeks to update, but physical ones as well. As the need for computer glasses.

It has been discovered sitting in front of a computer screen not only makes you a pain in the neck, causing creak in the ass, but it gives you eye problems as well. Even if you are wearing a pair of prescription, you may want to buy a pair of computer glasses. You can also buy attachments to go with what you already have.

Computer glasses are specially made. In regular prescription glasses, including bifocals, you usually find help in seeing better at closer range or long range. Except for a minute part trifocals, you do not have mid-range needed for a comfortable computer.

If you spend long hours in front of the computer, you may want to get computer glasses, if you need to be corrective lenses. Computer Vision Syndrome can cause numerous symptoms, which leads to loss of productivity. CVS can cause headaches, blurred vision, neck and shoulder pain, loss of focus, fatigue, burning eyes and double vision.

If you are over forty, some of these effects may be presbyopia and need to be checked carefully with an eye doctor. For those under forty, you’ve probably discuss CVS and require a computer screen glasses. If you do not wear prescription pair, then you may want to get computer glasses, however, as they also help with the glare from fluorescent lights. Your best bet would be to go to the eye doctor and ask for a test and reserve pair.

simplest pair of computer glasses that you can order individual was lenses vision. Changed their power helps keep the general user from some of the discomfort associated with CVS. For people with presbyopia, occupation progressive lens, would probably work best. The transitions area is much larger than the typical progressive lens and can even do some distant vision for you. They have added computer vision near and far as well as the central area. However, they are not good enough to run with. These glasses are not made for driving.

For some people it may be useful, even if not necessary, for them to get an occupational Bifocal. If you need reading glasses, this could be a good choice. Part of the lens is dedicated to close up work and the other half to the mid-distance commuting to work on the computer.

Again, go to the eye doctor for the best results. And do not wait until symptoms are so bad that the possibility of permanent damage comes into play.

Computer Vision Syndrome – What You Need to Know

[ad_1]

operating optometrist, I come very often the people who have no visible eye problem but complained headache, fatigue, strain the eyes and dry-eye. What all these people have in common foreign long hours working on the computer. Believe it or not, computer related eye problems recognized as a separate entity called “Computer Vision Syndrome” or CVS. In this era of technology, life without a computer is simply unimaginable for most of us. While some people just to check individual mail, there are others that their life and work depends on the computer. Young children are often hung on the charm of online gaming and adolescents are addicted to social networking sites. The IT industry is booming and all that was once manual is now computerized. Nevertheless, as much as it makes our lives easier, computers bring their own health risks.

When we work on a computer screen, our eyes and muscles leaving some physical and physiological changes. Our flashing rate- system is used to keep your eyes evenly moist drastically reduces as we are so engrossed in the screen and type “forget” to blink. This causes the tear film on our eyes to break and dry out quickly and cause burns and gritty feeling eventually leading to a red swollen eyes. Since the distance between the eyes and our computer screen is usually very less, have our eyes to have extra effort and “meet” so that the focus on an object on the screen. Doing this for a long time without breaking leads to fatigue, headaches and eyestrain. Not only the eyes, our work-place ergonomics also determines our posture and the beginning of or related problems like spondylitis and back pain. Unpleasant chair or low table can cause us to slouch and bend forward – the backbone of health effects in the long run. One might wonder why we can read books for hours and never get tired- so it is so different from a computer screen? Distance where we read books is much less distance where we put out a computer screen. Secondly, the image on the screen is made up of many dots that are brightest at the center and fade to limit the black pigment printing offers a uniform black-and-white contrast that our brain finds it easier to check. all the problems arising from the above discussed ways are collectively referred to as the “Computer Vision Syndrome”.

Computer Vision Syndrome is characterized by chronic eye strain, occasional blurred vision, dry or burning eyes, light sensitivity, head-ache and neck, shoulder or back pain. Most computer users to one or more of these problems to a greater or lesser extent. Unfortunately, these are often dismissed as “stress-related” or “lack of sleep”. Although CVS is not a disease in itself, it is definitely a concern because of the growing prevalence. Eye discomfort and other symptoms have a direct impact on the performance of the individual and personal well-being so that the impact / effectiveness of its work.

While Computer Vision Syndrome is fast gaining momentum, especially among young people and middle- aged, there are several methods that can be employed to ensure good eye health

-. Make sure that the workstation is comfortable and choose a chair that adequately supports your spine and it adjusted the height so that your feet rest comfortably flat on the floor. Awkward height either chair or table can cause unnecessary strain on your neck, backbone and eyes

-. If the child’s “screen child”, to ensure that your computer is limited to a few hours of heavy muscle work during the growing period, can interfere with normal growth and development of the visual system of the child

-. The computer screen should be placed at a level that is lower to your face so that your eyes are part of the eyelids while you work and not become too dry. Adjust the height so that the screen is a slightly lower price than your eyes while you sit upright and erect

-. Time regular breaks and spend 10-15 minutes to sit with eyes closed and / or focusing on a distant object like a tree outside your window. This exercise helps “stretch” the eye muscles reduces the risk of strain. Use an alarm clock or a reminder on your computer that will push you to take a break every hour or so

-. Avoid placing the computer in a place where it can reflect too much light (like the side window or far lamp). Use anti-reflection coating on the screen to minimize glare. Studies have shown that the symptoms of CVS was significantly less in patients using anti-reflection coating on the glasses of

-. Tilt the screen slightly down angle so that it does not reflect light directly into your eyes. You will be amazed at how effective this seemingly simple process turns out to be

– Another simple but useful tip is to use a “reverse contrast” on your screen. White letter on black background reduce the glare from the screen and provide better contrast. Always adjust the font comfortable and acceptable so you do not have to squeeze and squint while reading

-. Keep a package of preservative-free lubricating drops well for use in space-time, or even at your work-place. Believe me, they are very refreshing

– For those above forty, it is important to be wearing the proper correction. Talk to your eye care specialist on occupational demands and ask for the “intermediate” distance correction along lesgleraugu devices. Special “computer glasses” are now available that can be customized as per your requirements to ensure comfort and productivity.

Computer Vision Syndrome is just another addition to a long list of life-style caused problems, but the solution is relatively simple. Pay attention to details is after all worth the trouble if it promises better health and comfort for the eyes. Working on the computer as long as you want, but take care not to stress you out. Small steps go a long way in maintaining the health of your eyes and back. Remember, health is always first!

If so, you’ve Likely experienced a form of eyestrain Associated with prolonged computer use called computer vision syndrome. I’d like to talk to you about some Ways You Can Reduce, or Even Eliminate, the symptoms of this common condition.

Facts About Computer Vision Syndrome

The American Optometric Association reports That 70-75% of Americans WHO spend a lot of time in front of a computer have Computer Vision Syndrome! That’s right. Most people, howeverwhole, do not attribute the symptoms of this condition to computer use. They include:

• Headache

• Eye strain

• Blurred vision

• Shoulder and neck pain

• Dry, scratchy red eyes

Your eyes do not RESPOND to reading print on a computer screen the Same Way They do reading printed material from, say, a newspaper or magazine. That’s Because words in printed material stand out from Their background much more distinctly than words That Appear on a lighted computer screen. With the glare That comes from the lighted computer monitor screen, your eyes Constantly have to focus thousands of times Trying to read computer screen text.

Also, you blink less ofter reading computer text than regular text, in fact 5 times less, and this Causes the eye to become dry and irritated. In addition, the eye muscles become overworked and that’s where all the strain, headache, and neck pain comes from. Standard vision tests fail to properly Diagnose computer vision syndrome Because They only show how well Characters are seen up close and far away. Computer vision syndrome falls somewhere in the middle.

Can You Remedy Computer Vision Syndrome?

The question most frequently asked by my sjúklinga When We Discuss Their eyestrain is ” How Can I Avoid this condition if I have to work all day on a computer? ” Unfortunately, you can not completely Avoid the eyestrain symptoms of working on a computer all day.

5 simple ways to reduce the effects of Computer Vision Syndrome

[ad_1]

Computer Vision Syndrome is actually a word to describe the group of eye and vision problems related to near work which are experienced or related to computer use.

Some authorities Eye Health estimate that as much as 75% of people who work on your impact in some way by computer vision syndrome. If you experience any of the following, it can affect you as well.

1) tired, sore or burning eyes

2) eyestrain

3) periodic blurred near and distance vision

4) headaches

5) dry

6) slowness in changing the focus of the eyes

7) discomfort contact lens

8) flash sensitivity

9) excessive tearing

here are five simple things you can do to reduce the effects of Computer Vision Syndrome

1. Make sure your workstation, whether at work or at home, set up ergonomically

repositioning your monitor is an easy and effective way to avoid unpleasant head and eye movements. Because the eyes lead the body, your body will take any position, it is necessary to make the eyes to see comfortably. A badly located computer screen causes awkward body position. A viewing distance of 20-28 inches is the most common.

center of the computer screen should be 4-9 inches below your eyes, because the eyes work best with a little down gaze.

computer’s screen and other functions (phone, if it is part of the office) should be located directly in front of you so you do not have to look to the side or twist the body or neck to see them.

2. Eliminate flash in your work area

Flash is an all-too-common cause of eyestrain and eye fatigue. Change your office lighting will eliminate glare and harsh reflections. First, find the source of the flash: Does it come out of the window, task light, or the screen itself

If possible, remove the offending light source. Adjust blinds or curtains to minimize sunlight. Turn down the overhead lights so that the brightness of the screen and the surrounding air are balanced. Although not working in the dark :. Contrast between computer-generated light and the lack of light background strains my eyes

3. Adjust the screen

“Optimal contrast and visibility achieved with black letters on a white background. But other combinations can be comfortable as long as the display contrast between the characters and the background is high. It is best to avoid dark backgrounds. “

You can also adjust the brightness / contrast control devices, and use larger fonts, display legibility is an important factor in visual performance. For most, the size of the text should be three times the size of the smallest text you can read.

article on “Flat-Panel Monitors against CRTs” magazine PC World says that “flat panel (LCD) displays have visual advantages compared to the cathode ray tube (CRT) displays. They do not flicker and contrast is usually higher . “And because CRTs deteriorate gradually over time, you may not even realize that the picture you are looking at today is not the same as you were looking at five years when you bought screen-although this the decline may be cause Computer Vision Syndrome symptoms. Consider upgrading.

4. Take a break

It is easy to lose track of time on the computer. Always remember 10-10-10 rule and at the very minimum take a break at least once an hour for about 10 minutes and blink often – video display use was associated with reduced frequency of blinking. Computer use may also cause increased incidence of tear evaporation.

5. Be healthy

Although you can relieve dry, itchy eyes with artificial tears from the drugstore or supermarket, it is best to rely on them. A better way to prevent the desiccant liquid is to be fashioned with good H2O. Of course, eating beta-caro tine-rich foods is always good to maintain eye health and Japanese research suggests that the amino acid taurine supplementation appears to reduce visual fatigue. Contact lens wearers may want to switch to glasses of PC work, the lenses themselves can cause dry eyes.

There are also special eye ​​vitamin supplements to.

Computer Vision Syndrome – in the blink of an eye

[ad_1]

It is no secret that healthy employees make happy and productive workforce. Forget about the dangers of hostile working conditions in places such as radiators or chemical laboratories; even innocuous office today poses his own threat. Computers have undoubtedly made our lives easier, but regular use is strongly associated with certain unpleasant consequences. Computer Vision Syndrome (CVS) is a term used to describe the ill effects arising from spills or improper use of the computer. As a responsible employer, it is your duty to ensure that staff are suffering from it as little as possible.

Computer Vision Syndrome affects people in different ways by creating a vision, eye or physical discomfort or a combination thereof. Effects Computer Vision Syndrome can be minimized by taking certain measures, some of which include a change in work habits, while others related to changes in the layout of the workplace. Let’s start with the latter.

It is in the air. Lots of CVS victims complain about itching and dry eyes. Setting the humidity levels in the office and direct the air flow so that neither hot nor cold air blows right on the faces of people, can bring relief.

see things in perspective. Who has not experienced discomfort tired and blurry eyes at the end of a long day of work? Improper lighting and too many reflections off different surfaces combine to create eye strain. Throw in a computer screen, and Wham! you are already feeling the mother of all headaches coming on. Make sure your office lighting is designed properly – which means using less bright or indirect sources, reduce glare by ensuring windows covered or even hire colors that are less reflective. Interestingly, you can use illuminated keyboard that helps reduce eyestrain on the evening of the use of computers.

Take a screen test. Computer monitors are a good source of unwanted thoughts – you want to look at the files, not open grill, in the name of Jesus! Have all screens equipped with anti glare cover, and encourage the use of attachable owners document. If you want a more sophisticated solution, check out the range of products from Imate specifically intended to combat CVS. And let users know that high brightness mode and display more than 6 colors on the move is not going to help his cause. Of course, none of this is any good if the monitors are not kept clean and dust free. A gentle rap on the knuckles should sort out offenders nice and proper!

Learn the body language. The workstation must be designed to suit the human body, and not the other way around. The biggest pain in the neck in the office is no longer curious colleague; it is not-so-friendly desktop computer! Computer screens will be set about 4 to 8 inches below eye level, so that the top line is 15 degrees below the line of sight. Chairs should be ergonomically designed and adjustable for individual body contours. Make sure that there is enough space to stretch your legs people and the table is large enough to accommodate the wrist and elbow ….

Besides all this, you can remind office workers to change their habits to reduce stress resulting from Computer Vision Syndrome. Place announcements encouraging people to drink plenty of water, do gentle exercises, take regular breaks and blink!

Low Vision – What is Computer Vision Syndrome

[ad_1]

?

computer vision syndrome (CVS) is a group of eye and vision-related problems that result from prolonged computer use. Many people experience eye discomfort and vision problems when viewing a computer screen for a longer period, with the level of discomfort with the increasing amount of computer use

The most common symptoms associated with computer vision syndrome include :.

  • eyestrain
  • headache
  • blurred
  • dry eye
  • neck and shoulder pain

These symptoms may be caused by:

  • poor lighting
  • flash on a computer screen
  • improper viewing distances
  • poor seating posture
  • uncorrected vision problems

View computer screen often makes eyes work harder. As such, the unique characteristics and high visual demands of computer see many individuals susceptible to the development of vision symptoms. The extent to which people experience visual symptoms often at the level of visual ability and time spent looking at a computer screen. Many of the visual symptoms experienced by computer users are temporary and will decrease after stopping the computer work. Some people hardly continue my visual skills such as blurred distance vision, even after cessation of work on the computer. If nothing is done to address the cause of the problem, the symptoms will continue to recur and may become worse with the future of computing.

uncorrected vision problems, such as farsightedness and astigmatism, inadequate eye focusing or eye coordination abilities, and aging changes in the eyes, such as presbyopia, can increase the severity of the symptoms of CVS. Uncorrected vision problems can contribute to the development of visual symptoms when using a computer.

prevent or reduce vision problems associated with CVS involves taking steps to control lighting and flash on a computer screen, bring good distance and posture for computer viewing, and ensure that even minor vision problems are properly adjusted.

Computer Vision Syndrome

[ad_1]

Almost everyone these days is to use your computer for work or play. We spend a lot of time staring at computer screens and our people are experiencing vision problems. The eyestrain, blurred vision and headaches that often come with a computer called Computer Vision Syndrome (CVS).

Research suggests that up to 80% of computer users have vision problems or CVS. Many computer users do not associate their symptoms with the time they spend on the computer. Some assume that their headaches or eyestrain from work stress or tired, their eyes are expected part of their work. Computer glasses are special glasses designed for computer environments. They will make your computer time more productive and comfortable.

One of the causes of CVS is because the nature of text and graphics on a computer screen. The image on the monitor is equipped with pixels of light, are glowing dots are the brightest in their center with their luminance fall to zero to the edge of the bell-shaped fashion. Print on paper usually has a sharp, high contrast edges.

The human visual cortex has special cells that are very good at recognizing high contrast edges as printed on paper. These cells are an important basis for our visual perception system, because much of what we consider to be a “thing” in nature is shaped by high-contrast edges. Our eyes can lock in sharp contrast edges but have a difficult time maintaining focus accurately on pixel-created edge.

Looking at the computer screen, have our eyes have muscles attempt to focus on the distance and will remain to keep the forces as long as we are looking at the screen. In fact, what happens is concentrating efforts relaxes gradually and then return focus to the plane of the screen. Over time, the muscles fatigue and CVS symptoms occur

Computer Ergonomics :.

  • Description in most offices is too bright for comfortable computing. If you can reduce lighting anything that will help. Watch the flash from doors, windows or reflected glare from the surface. If you wear glasses when working on the computer they should have a reflective coating on them.
  • To minimize stress and eyestrain, the screen should be 20-30 inches away from your eyes. You should be looking slightly down at 15 degree angle. Use an adjustable chair with full Back Support
  • In many offices, the air is dry due to the air conditioning and heater. When eyes become dry vision fades and eyes feel irritated. To make it worse, when we stare at the computer our rate of blinking slowly, wiped his eyes even more. Lubricating eye drops often help.

If you are experiencing eyestrain, blurred vision and headaches related to computer use, see an eye doctor. Why put up with eyestrain, blurred vision and headaches if you do not?
