Correcting Astigmatism with Contact Lenses
Astigmatism for a long time was an eye problem that could not be fully corrected with contact lenses. Mild astigmatism could be adequately improved with soft contact lenses, but there weren’t options for more severe cases. The eye problem itself results from a misshaped cornea - rather than being spherical like a ball, the cornea in people with astigmatism is oblong, shaped more like a football. Because of this shape, light rays can’t refract properly against the retina. Instead of focusing the rays on one spot, the odd shape causes light to refract in multiple locations on the retina, causing the blurred vision, regardless of distance, that is symptomatic of astigmatism.
Routine eye exams are important even for people who are not experiencing eye trouble. How often a person needs an eye exam depends on a number of factors including age, overall health and whether or not eye disorders run in the family. ..
