From My Mom

Here's some stuff you can read about glasses that my mom found at this site:

How can a child be tested for glasses, especially in infancy or early childhood?

An ophthalmologist can detect the need for glasses through a complete eye exam. Typically, the pupils are dilated in order to relax the focusing muscles, so that an accurate measurement can be obtained. By using a special instrument, called a retinoscope, your eye doctor can arrive at an accurate prescription. The ophthalmologist will then advise parents whether there is a need for glasses, or whether the condition can be monitored.

What are the different types of refractive errors (need for glasses) that can affect children?

There are 4 basic types of refractive errors:

  1. Myopia (near-sighted)
  2. Hyperopia (far-sighted)
  3. Astigmatism – Astigmatism is caused by a difference in the surface curve of the eye. Instead of being shaped like a perfect sphere (like a basketball), the eye is shaped with a greater curve in one axis (like a football). If your child has a significant astigmatism, fine details may look blurred or distorted. Glasses that are prescribed for astigmatism have greater strength in one direction of the lens than in the opposite direction. A prescription for astigmatism will have several numbers and will look something like this: -2.00 +2.50 X 90.
  4. Anisometropia – Some children may have a different prescription in each eye. This can create a condition called amblyopia, where the vision in one eye does not develop normally. Glasses (and sometimes patching) are needed to insure that each eye can see clearly.

How will I ever get my child to wear glasses?

That is a question most parents ask, especially when their child is an infant or toddler. The best answer is that most young children who really need glasses will wear their glasses without a problem (happily) because they do make a difference in their vision. Initially, some children may show some resistance to wearing their glasses, but it is necessary for parents to demonstrate a positive attitude. Toddlers often may wear the glasses only when they are in a good mood and reject them (and everything else) when they are not. Getting a good frame fit by an optician who is experienced in pediatric eyewear is also of great importance. The frame should be very comfortable with the eye centered in the middle of the lens. The frame should look like it fits the child now — not one that he/she will grow into in a year. Lenses made of a material called polycarbonate will provide the best protection for your child because this lens material is shatterproof. Many children’s frames have soft, comfort-cables that fit around the ears.

School age children and their parents can provide input into the decision regarding the need for glasses. Some children may have small refractive errors that do not require glasses, while others may voice concern about difficulties in the classroom. Most children who have difficulty with reading do not need glasses, but this can be determined in the complete eye exam.

Will wearing glasses make my child’s eyes worse or more dependent on them?

No. In fact, the opposite may be true. If a child does not wear the glasses prescribed, normal vision development can be adversely affected.
