Babies (Aged 3yrs and below)
Ensure that your child has his or her eyes screened during regular paediatric appointments. Some childhood eye conditions to look out for include squints (crossed eyes), lazy eye (amblyopia), and childhood myopia.
If your child is a premature baby (baby born before the completion of the pregnancy term), then the child should be screened by a retinal surgeon for retinal abnormality (retinopathy of prematurity).
Children and Teenagers (Aged 4 to 16)
The child's vision should be tested at the age of 4 years old. Ensure that the child has an eye examination every one to two years during routine health check-ups.
Young adults (Aged 17 to 39)
Have a comprehensive eye examination if you have a family history of eye disease or you are suffering from an eye injury.
Adults and seniors (Aged 40 and above)
As one gets older, age-related eye conditions are more likely to crop up. Look out for common eye symptoms like vision changes or pain, flashes or floaters, distorted lines, dry eyes that itch and burn. To keep tabs on any vision changes, adults should get a baseline eye screening when they are 40. Your doctor will assess how often you need to return for follow-up screenings.
For anyone with risk factors
If you have a risk factor for eye disease (you have diabetes, high blood pressure, a family history of eye disease like glaucoma, or are taking prescription medications which affect the eyes) you should see your ophthalmologist more frequently. Ask your eye doctor what the ideal interval between check-ups is.
There are no exercises or medicines available which can reduce the power of glasses. What is more important is that clear vision is maintained & the glasses are regularly updated. However, one can reduce eyestrain by improving reading & dietary habits.
Many a time, kids are unable to express their opinions clearly due to fear or alterations in mood. Since children have strong accommodation, accurate checking needs to be done after dilatation of the pupil, which may even take 2-3 sittings.
Hereditary may play an important role in some cases. However it is not necessary that children of parents with high power should have glasses or vice versa.
Computer users should have an eye examinaton 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.
When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices. If possible, position your computer monitor or screen so windows are to the side, instead of in front or behind it.
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.
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. When choosing a new flat panel display, select a screen with the highest resolution possible.
Finally, choose a relatively large display. For a desktop computer, select a display that has a diagonal screen size of at least 19 inches.
Adjusting the display settings of your computer can help reduce eye strain and fatigue. Generally, these adjustments are beneficial:
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.
b.) 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.
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.
Another cause of computer eye strain 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.
To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day.
During your computer breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to reduce tension and muscle fatigue.
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 centre of your screen should be about 10 to 15 degrees below your eyes for comfortable positioning of your head and neck.
For the greatest comfort at your computer, you might benefit from having your eye care professional modify your eye glasses 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.
