Nearsightedness or myopia, occurs when light
entering the eye focuses in front of the retina
instead of directly on it. This is
caused by a cornea that is steeper, or an eye that is
longer, than a normal eye. Nearsighted
people typically see well up close, but have difficulty seeing far away.
This problem is often discovered in school-age
children who report having trouble seeing the chalkboard.
Nearsightedness usually becomes progressively worse through
adolescence and stabilizes in early adulthood.
Signs and Symptoms
- Blurry distance vision
- Vision seems clearer when squinting
Detection and Diagnosis
Nearsightedness is detected with a vision
test and refraction.
The treatment for nearsightedness depends on several factors
such as the patientís age, activities, and occupation. Vision
can be corrected with glasses, contact lenses or surgery.
Refractive procedures such as LASIK can be considered for
adults when the prescription has remained stable for at least
