My son took many eye exams. His last one showed 20/20 vision. At a children’s eye specilist. Although, he has bad astigmatism. Because of this he was prescribed glasses, -2.50 and -2.25. He was told to where them as often as possible. Why is this?
Astigmatism is usually discovered during routine eye exams when your doctor checks your eye’s refraction and visual acuity using standard eye charts. Refraction is the ability to properly focus light rays on the retina and can be measured in a number of ways. Some doctors will ask a series of questions and conduct a visual acuity test, while others will use a keratoscope or keratometer to measure the curvature and shape of your cornea to determine your degree of astigmatism.
Astigmatism can be corrected thru the use of corrective lenses, involving either glasses or contact lenses. Astigmatism can also be corrected with refractive eye surgery.
Corrective lenses are a conservative method of dealing with astigmatism. Glasses and contact lenses are able to counter the effects of the irregularly shaped cornea and provide vision considerable improvement.
Ortho-K is an alternative method that uses special contact lenses that actually reshape the cornea. These special lenses are worn only at night and they gradually reshape the cornea by applying pressure in the right way.
