Astigmatism – Blurry Vision
Astigmatism is blurry or distorted vision caused by irregularities in the curvature of the eye’s cornea or lens. In essence, the vast majority of people have at least a minor degree of astigmatism.
If one’s astigmatism is minor enough to cause no noticeable symptoms, then it often does not require treatment. However, if it is significant enough to cause noticeable vision distortion, squinting, eye strain, headaches, and/or eye fatigue, then corrective action in the form of eyewear or LASIK will often be recommended.
Presbyopia – Aging Eyes
Just like any fine instrument, our eyes can eventually degrade and lose precision. In presbyopia, the lens starts to slowly lose flexibility, making the tasks of bending light and focusing on close-up objects more difficult. Vision at greater distances does not tend to be substantially affected by this condition.
While there is little that can be done to prevent this gradual breakdown, it is still treatable via corrective lenses. Bifocals, trifocals, reading glasses, and monovision or multifocal contact lenses can all be effective tools in restoring clear vision.
