10 Tips for computer eye strain relief – allaboutvision.com best antiemetic for children

During your exam, be sure to tell your eye doctor how often you use a computer at work and at home. Measure how far your eyes are from your screen when you sit at your computer, and bring this measurement to your exam so your eye doctor can test your eyes at that specific working distance. 2. Use proper lighting.

Eye strain often is caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting. When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices.

Eliminate exterior light by closing drapes, shades or blinds. Reduce interior lighting by using fewer light bulbs or fluorescent tubes, or use lower intensity bulbs and tubes. If possible, position your computer monitor or screen so windows are to the side, instead of in front or behind it.

Many computer users find their eyes feel better if they can avoid working under overhead fluorescent lights. If possible, turn off the overhead fluorescent lights in your office and use floor lamps that provide indirect incandescent or halogen lighting instead.

Sometimes switching to full spectrum fluorescent lighting that more closely approximates the light spectrum emitted by sunlight can be more comforting for computer work than regular fluorescent tubes. But even full spectrum lighting can cause discomfort if it’s too bright. Try reducing the number of fluorescent tubes installed above your computer workspace if you are bothered by overhead lighting. 3. Minimize glare.

Glare on walls and finished surfaces, as well as reflections on your computer screen also can cause computer eye strain. Consider installing an anti-glare screen on your monitor and, if possible, paint bright white walls a darker color with a matte finish.

While more research is needed to determine if prolonged digital device use causes permanent damage to the eyes, many eye doctors are concerned about the effects of blue (HEV) light emitted from digital devices. Animal studies have shown that exposure to high levels of HEV light can damage tissue in the retina, possibly leading to conditions like macular degeneration.

Players should follow the 20-20-20 rule: take a break every 20 minutes and look at something 20 feet away for at least 20 seconds. This exercise helps relieve digital eye strain, which can cause dry or irritated eyes, blurred vision and more. — N.B. 4. Upgrade your display.

LCD screens are easier on the eyes and usually have an anti-reflective surface. Old-fashioned CRT screens can cause a noticeable flicker of images, which is a major cause of computer eye strain. Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work.

When choosing a new flat panel display, select a screen with the highest resolution possible. Resolution is related to the dot pitch of the display. Generally, displays with a lower dot pitch have sharper images. Choose a display with a dot pitch of .28 mm or smaller.

If you see a lower refresh rate (e.g. 60 Hz) noted on an LCD screen, don’t worry — this refers to how often a new image is received from the video card, not how often the pixel brightness of the display is updated, and this function typically is not associated with eye strain.

You can adjust text size when using Internet Explorer, Firefox, Safari and other browsers, too. For example, in Firefox, you can enlarge an entire webpage by using the keyboard command Ctrl + as many times as you want, while Ctrl 0 makes everything normal-sized again. (Ctrl – makes everything smaller.) To enlarge only the text, use Alt V, then Z, then T. Then use Ctrl + again, and you’ll see just the text enlarging.

Many smartphones let you adjust text size. For example, on the iPhone 4, you simply open the Settings menu, then choose General, then Accessibility, then Large Text. Here you can choose a new font size for core applications such as Mail, Notes and Calendar. The font will also display in certain third-party applications.

Tears coating the eye evaporate more rapidly during long non-blinking phases and this can cause dry eyes. Also, the air in many office environments is dry, which can increase how quickly your tears evaporate, placing you at greater risk for dry eye problems.

By the way, don’t confuse lubricating eye drops with the drops formulated to get the red out. The latter can indeed make your eyes look better — they contain ingredients that reduce the size of blood vessels on the surface of your eyes to whiten them. But they are not necessarily formulated to reduce dryness and irritation.

The survey, conducted by The Vision Council, likewise revealed that adults keep their doctors in the dark about their own digital device habits. An alarming 68.5 percent reported that they had not discussed their digital device usage with their eye care provider, and 73.5 percent reported that they did not know eyewear can protect eyes from the short- and long-term effects of blue light exposure and digital eye strain.

The optical industry has recognized and responded to the increase in digital habits and has developed lens and coating technology to protect the eyes from blue light, glare and other environmental stressors, ultimately to improve the way people see, says Ashley Mills, CEO of The Vision Council. To help raise awareness, the group has launched a consumer outreach initiative. Download the one-page report here. — Amy Hellem 8. Take frequent breaks.

Many workers take only two 15-minute breaks from their computer throughout their work day. According to a recent NIOSH study, discomfort and eye strain were significantly reduced when computer workers took four additional five-minute mini-breaks throughout their work day.

And these supplementary breaks did not reduce the workers’ productivity. Data entry speed was significantly faster as a result of the extra breaks, so work output was maintained even though the workers had 20 extra minutes of break time each day.

Check your local bookstore or consult your fitness club for suggestions on developing a quick sequence of exercises you can perform during your breaks and after work to reduce tension in your arms, neck, shoulders and back. 9. Modify your workstation.

Purchase ergonomic furniture to enable you to position your computer screen 20 to 24 inches from your eyes. The center of your screen should be about 10 to 15 degrees below your eyes for comfortable positioning of your head and neck. 10. Consider computer eyewear.

For the greatest comfort at your computer, you might benefit from having your eye care professional modify your eyeglasses prescription to create customized computer glasses. This is especially true if you normally wear contact lenses, which may become dry and uncomfortable during sustained computer work.

Computer glasses also are a good choice if you wear bifocals or progressive lenses, because these lenses generally are not optimal for the distance to your computer screen. Also, you may want to consider photochromic lenses or lightly tinted lenses for computer eyewear to reduce your exposure to potentially harmful blue light emitted by digital devices. Ask your optician for details.
