Nearsightedness

Nearsightedness
Myopia occurs when the cornea is too curved or the eye is too long. This causes light to focus in front of the retina, resulting in blurry distance vision.

Myopia is a very common condition that affects nearly 30 percent of the U.S. population. It normally starts to appear between the ages of eight and 12 years old, and almost always before the age of 20. As the body grows, the condition often worsens. It typically stabilizes in adulthood.

Diagnosing myopia:
Many times, myopia is diagnosed during school screenings. Sometimes parents notice that their children are having difficulty seeing street signs or the television. Dr. Hyder can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Dr. Hyder will also check your eye coordination and muscle control, as well as your eyes` ability to change focus. All of these are important factors in how your eyes see.

Treatment of myopia:
Glasses and contact lenses are used by many for the temporary treatment of myopia. However, there are a number of vision correction procedures that can surgically reduce or eliminate myopia.

Farsightedness
Hyperopia occurs when the cornea is too flat in relation to the length of the eye. This causes light to focus at a point beyond the retina, resulting in blurry close vision and occasionally blurry distance vision as well. Usually this condition is undetected until later in life because the young eye is able to compensate for the hyperopia by contracting the internal lens of the eye.

Diagnosing hyperopia:
Many people are not diagnosed with hyperopia without a complete eye exam. School screenings typically do not detect this condition because they test only for distance vision. Dr. Hyder can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Dr. Hyder will also check your eye coordination and muscle control, as well as your eyes ability to change focus. All of these are important factors in how your eyes see.
