Reliable detection of Win98 may not be possible. When a child goes to see an ophthalmologist, the doctor asks the parents about the child's symptoms because parents are often the first to notice a child's eyesight problems. A mom or dad may tell the doctor that his or her baby doesn't seem to focus on him or her or doesn't react to lights that are turned on or off. If another doctor notices a problem during a regular eye exam, the doctor usually will send the child to the eye specialist for a closer look at the problem.
Older children can answer questions about their vision.
A doctor might use an eye chart to find out how well they see. You may have seen one of these charts if you've had a vision test. You were probably told to cover one eye at a time and read numbers or letters from a chart on the wall. The doctor or nurse compares your eyesight with what is considered very good vision, which is the ability to see letters and numbers of a certain size clearly from 20 feet away. The numbers change depending on how clearly you can see at different distances.
