How to Diagnose and Treat Computer Vision Syndrome
This is the major way to diagnose CVS. An ophthalmologist may need to carry out an eye examination to see how the eyes work in response to distances from the computer screen. This would help ascertain the exact problem and how to deal with it.
There are two major ways of treating CVS. We`ll discuss some of them briefly.
This may include contact lenses or glasses. The glasses may be single, bifocal, or tinted lenses which you wear while you operate gadgets.
Carrying out some changes in your workplace and home can be helpful in combating CVS. Let`s see some of them.
- Position your computer screen such that it is below eye level and about 20-28 inches away from your face.
- Adjust the font size and brightness of your computer to avoid straining your eyes.
- Give your eyes a break every 20 minutes by looking about 20 feet away for 20 seconds every 20 minutes. This is called the 20-20-20 rule.
How to Prevent Computer Vision Syndrome
- Do regular eye checkups.
- Consume diets rich in various vitamins and minerals.
- Use an anti-glare screen filter on your gadgets.
- Follow the 20-20-20 rule.
- Take 15-minute breaks after every two hours of using gadgets.
- Lubricate your eyes with artificial tears, or place a humidifier close to your screen if your eyes feel dry often.
- Your room or office should be bright enough for your screens. It`s unhealthy to use bright screens in dark environments
- If you wear contact lens, you could wear your glasses instead while using your computer.
- Practice eye exercises such as rotating your eyes in the clockwise direction, blinking slowly, or occasionally looking far away for some seconds.
Proper Body Position while Using a Computer
Maintaining proper body positions while using a computer also serves as a way of preventing computer vision syndrome. Here are some helpful tips:
- Sit close to the keyboard and position it directly in front of your body, so you don`t have to tilt while operating the computer.
- Ensure that your shoulders are relaxed, and your wrists and hands are parallel to your keyboard.
- Resting your wrists may be helpful in preventing pain.
- Sit at an arm’s length from your computer screen.
- Position your computer screen slightly below your eye level, such that the center of the screen is at least 10-15 degrees below eye level.
- The center of the screen should be at least 10-15 degrees below eye level.
Other Ways to Care for your Eyes
These tips, in addition to preventive or curative measures for CVS, will get your eyes to a state of good health.
Eat Healthy Foods
Eat foods rich in Vitamins A and C, beta carotene, and lutein because they help repair the eyes. Such foods include sweet potatoes, butter, papaya, cod liver oil, blueberries, grapes, and apricot. Greens are also super beneficial. You can have some collard greens, zucchini, kale, spinach, or Brussels sprouts.
Get Adequate Rest
Getting enough rest is quite important, as sleep helps overworked eye muscles to relax.
Keep your Hands Clean
It is important that you keep your hands clean at all times to maintain healthy eyes. This is because touching the eyes is unavoidable, hence you may be infecting your eyes with dirt and germs if your hands aren`t clean. Also, remember to wash your hands properly before changing your glasses or contact lens.
Washing the hands may not be possible at all places and all times required, hence taking a portable container of hand sanitizer around may be helpful. It may not be as effective as washing your hands, however, it`ll help you disinfect them to a large extent.
Increasing your water intake would be quite helpful. You may also wash your face occasionally, and at other times, fill your mouth with water and splash it out with your eyes wide open. This will help you feel refreshed.
Protect your Eyes from Sun Rays
Excessively exposing your eyes to ultraviolet rays of the sun may cause severe damage to your eyes. It may lead to macular degeneration or some other ocular conditions. There are various ways of protecting your eyes, some of which are wearing UV protected glasses or contact lenses, using an umbrella, or wearing a hat when it`s sunny.
Smoking is associated with a number of ocular diseases. It damages the optic nerves and over time causes impaired vision. For your eyes and overall health, stop smoking.
Know your Family Eye Health History
There are people who, notwithstanding the exposure they have to digital devices, their eyes remain healthy. However, there are others who are susceptible to having ocular conditions. Genetics is a major factor here. Even though you can`t change it, knowing it (early especially) would make you proactive, hence prevent likely eye health conditions.
Exercise Your Eyes
Practice relaxation exercises. For instance, after a while of sitting before your computer, you may place your hands together palm to palm, then rub them together briskly to create some heat, then immediately place them over your eyes; and as you close your eyes, imagine some relaxation. You will actually feel relaxed. Keeping your hands clean at all times is essential if you will be doing this.
Use Less Eye Makeup
Eye makeups contain harmful chemicals that may cause eye issues, especially when they`re overused. Also, when you use them, remember to wash them off properly, and not leave them overnight, as that may cause bacterial buildup. What`s more? Ensure that the brushes you use to apply makeup are clean, as they may introduce germs into your eyes.
