Computer Eye Strain
Steps for Relief
With so many of us using computers at work, computer eye strain has become a major job-related complaint. Studies show that eye strain and other bothersome visual symptoms occur in 50 to 90 percent of computer workers.
These problems can range from physical fatigue, decreased productivity and increased numbers of work errors, to minor annoyances like eye twitching and red eyes.
Here are easy steps you can take to reduce your risk of computer eye strain and other common symptoms of computer vision syndrome (CVS):
1. Get a comprehensive eye exam
Having a routine comprehensive eye exam is the most important thing you can do to prevent or treat computer vision problems.
According to the National Institute of Occupational Safety and Health (NIOSH), computer users should have an eye exam before they start working on a computer and once a year thereafter.
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.
Again, cover the windows. When outside light cannot be reduced, consider using a computer hood.
If you wear glasses, purchase lenses with anti-reflective (AR) coating. AR coating reduces glare by minimizing the amount of light reflecting off the front and back surfaces of your eyeglass lenses.
If your older monitor is causing computer eye strain, replace it with a flat-panel LCD screen that is easier on the eyes.
4. Upgrade your display
If you have not already done so, replace your old tube-style monitor (called a cathode ray tube or CRT) with a flat-panel liquid crystal display (LCD), like those on laptop computers.
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 eyestrain. Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work.
Complications due to flicker are even more likely if the refresh rate of the monitor is less than 75 hertz (Hz). If you must use a CRT at work, adjust the display settings to the highest possible refresh rate.
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.
Flicker is not an issue with LCD screens, since the brightness of pixels on the display are controlled by a 'backlight' that typically operates at 200 Hz.
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.
Finally, choose a relatively large display. For a desktop computer, select a display that has a diagonal screen size of at least 19 inches.
5. Adjust your computer display settings
Adjusting the display settings of your computer can help reduce eye strain and fatigue. Generally, these adjustments are beneficial:
Brightness.: Adjust the brightness of the display so it's approximately the same as the brightness of your surrounding workstation. As a test, look at the white background of this Web page. If it looks like a light source, it's too bright. If it seems dull and gray, it may be too dark.
Text size and contrast.: Adjust the text size and contrast for comfort, especially when reading or composing long documents. Usually, black print on a white background is the best combination for comfort.
Color temperature.: This is a technical term used to describe the spectrum of visible light emitted by a color display. Blue light is short-wavelength visible light that is associated with more eye strain than longer wavelength hues, such as orange and red. Reducing the color temperature of your display lowers the amount of blue light emitted by a color display for better long-term viewing comfort.
For computers running on a Microsoft Windows operating system, display settings can be adjusted in Control Panel. For an Apple computer, display settings are found in Systems Preferences (in the Applications folder in Finder).
In some cases, the color temperature of a desktop computer monitor is adjusted on the display itself.
6. Blink more often
Blinking is very important when working at a computer; blinking moistens your eyes to prevent dryness and irritation.
When working at a computer, people blink less frequently - about one-third as often as they normally do - and many blinks performed during computer work are only partial lid closures, according to studies.
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.
If you experience dry eye symptoms, ask your eye doctor about artificial tears for use during the day.
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.
To reduce your risk of dry eyes during computer use, try this exercise: Every 20 minutes, blink 10 times by closing your eyes as if falling asleep (very slowly). This will help rewet your eyes.
To ease eye strain, make sure you use good lighting and sit at a proper distance from the computer screen.
7. Exercise your eyes
Another cause of computer eyestrain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds. Some eye doctors call this the '20-20-20 rule.' Looking far away relaxes the focusing muscle inside the eye to reduce fatigue.
Another exercise is to look far away at an object for 10-15 seconds, then gaze at something up close for 10-15 seconds. Then look back at the distant object. Do this 10 times.
This exercise reduces the risk of your eyes' focusing ability to 'lock up' (a condition called accommodative spasm) after prolonged computer work.
Both of these exercises will reduce your risk of computer eye strain. Also, remember to blink frequently during the exercises to reduce your risk of computer-related dry eye.
8. Take frequent breaks
To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day.
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.
During your computer breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to reduce tension and muscle fatigue.
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
If you need to look back and forth between a printed page and your computer screen, this can cause eye strain. Place written pages on a copy stand adjacent to the monitor.
Light the copy stand properly. You may want to use a desk lamp, but make sure it doesn't shine into your eyes or onto your computer screen.
Improper posture during computer work also contributes to computer vision syndrome. Adjust your workstation and chair to the correct height.
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.

Sildenafil (Viagra), whose function is to inhibit a substance called Phosphodiestarase-5 or PDE5 - was initially used only for the treatment of angina pectoris (a cardiovascular problem) and pulmonary hypertension. Incidentally, it was discovered that it could help the issue of erectile dysfunction too, and thus became hugely popular in the late 1990s. The little blue pill, as it was called, ruled more than 50% of the sexual dysfunction market for more than 15 years. However, as its popularity and usage increased, so did the scientific information about this drug, and now there is an increased speculation that it could be contributing to skin cancer, specifically melanoma. This is considered as one of the most dangerous forms of skin cancer and so the safety of Viagra sildenafil came into question.
Research has shown that users of Viagra sildenafil are at a higher risk for developing melanoma. There are reports stating that about 45 million men are at an increased risk of developing melanoma due to associated Viagra sildenafil use. The risk of developing melanoma was found to increase in men using ED drugs by 21%. Though there is no conclusive proof as yet that sildenafil is the cause, research is increasingly pointing out its role in melanoma. For example, PDE5 inhibitors (sildenafil, tadalafil, vardenafil) are known to promote melanin synthesis, which may exacerbate melanoma development.
The analysis of biochemical pathways of this correlation suggests that Viagra sildenafil triggers a special biochemical action involving the growth-stimulating cGMP (cyclic guanosine monophosphate (an intracellular signaling molecule) which in turn promotes the growth of malignant melanoma. In normal cases, the enzyme phosphodiesterase type 5 (PDE5) regulates the cGMP preventing any adverse cellular activity. Sildenafil inhibits the production of this enzyme, and potentiates a specific cGMP-related biochemical mechanism (called cGMP-cGKI pathway) , and thereby contributes to malignant melanoma. This has been proven to happen in mice and is yet to be proven in humans.
However, there are also reports which suggest that this does not happen due to Viagra sildenafil per se, but due to greater exposure to sun, which even otherwise increases the chances of skin cancer in general, and melanoma in particular. The countering theories also say that the population in which skin cancer was detected, comprised mostly of high income individuals who spent a significant amount of time holidaying on beaches and are not connected to the extensive use of Viagra per se.
Therefore, though there is a correlation that has been established, there is no definite proof that Viagra sildenafil causes skin cancer. It is however, advisable to use ED drugs after medical consultation. If a patient has a genetic predisposition to develop melanoma, it is advisable to seek medical advice before the use of ED drugs. Occasional use should not be harmful. Also, when going out in the sun, limiting exposure to direct sun and UV protection should be managed too.

1. Drink a cup of boiled water in the morning before breakfast. This seems to cleanse the stomach and often works wonders.
2.Eat slowly. One of the main causes of indigestion is unchewed food.
3.Don’t eat food “piping hot”. Our stomachs are not meant to have hot foods inside them. A useful thing to remember is that if it is hot in the mouth it is hot in the stomach. This includes tea and coffee. Food and drinks that are too hot may disrupt enzymes and injure the lining of the stomach. So, always wait for it to cool.
4.Don’t eat on the hoof. Meals should be taken at a leisurely pace. If you eat on the move, there is more chance that digestion will not begin. Instead foods in the stomach and intestine will start to ferment, producing gases that bloat you.
5.Avoid eating fruit with the meal. Tempting though it is, because it seems lighter on the stomach than puddings, it is not good at the end of a meal. This is because fruit digests faster than dense proteins, so fermentation and gas accumulation may occur.
6.If bloating is a persistent problem, try simplifying your meals. Instead of having lots of food groups at one meal try separating them. For example, proteins need acid enzyme digestive juices, whereas carbohydrates need alkaline enzyme digestive juices. When you have to break down both types all at once you are not achieving optimal enzymatic action, so some fermentation and gas accumulation may occur.
7.Try taking slightly smaller servings and think twice about second helpings. As a good rule of thumb, try to get into the habit of estimating the quantity you allow yourself using “nature’s food bowl”. Cup your two hands together as if you were using them to make a bowl. The quantity of food that would fill that “bowl” should be your maximum at any meal.
8.Make sure that you drink enough water. Ideally, hydrate your stomach with a glass of water half an hour before a meal.
