We Do More Than Test Eyes
Good vision is so much more than just focus.!
Ideal vision, sometimes called 20/20 vision, simply means that the person can clearly see a particular sized letter at 20 feet. Effective vision involves many different functions of the eye and also the brain.
The eyes are like cameras. They record 2 separate images. The brain interprets the information from the eyes, and forms the two image into one. Binocular vision. At the back of your brain is a large area called the visual cortex, that is dedicated to this job. When the eyes do not work together as the brain expects, or the brain interprets the information in a way that is not helpful we can have problems.
In children, development of vision can be delayed, or altered by changed functions of the eyes and brain. Optometrists can identify vision problems.
How Often Should Eyes Be Examined?
Everyone should have regular eye tests, although the frequency depends on your age, your health and your risk of developing eye problems. Optometrists generally recommend that you have an eye test every two years not only to detect and to diagnose vision changes or problems -- but, also to maintain eye health.
For example, glaucoma, a disease caused by increased pressure in the eye, commonly goes unnoticed by adults. Regular vision examinations are also important for the prevention of vision problems created or aggravated by today's academic and professional demands.
People over the age of 60 should have an eye examination every year. Eye examinations may be required more often if you have vision problems, or known diseases such as diabetes or glaucoma.
The American Academy of Ophthalmology and the Australian & New Zealand College of Ophthalmology recommends that children should have eye examinations:
As soon as possible if there is a family history of vision problems such as eye turn, lazy eye, or high degrees of long or shortsightedness.
At age 3 onwards to ensure there are no signs of a lazy or turned eye, or high degrees of long or shortsightedness.
Between 3 and 5 years if significant hyperopia is found, then regularly.
When they start school if their progress is significantly slower than expected, to check for vision problems which could be interfering in learning to read, or using their eyes to read and write
