Poor eyesight is never an easy thing to deal with, especially without the aid of some optical instruments like the eyeglasses or spectacles. Myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism (distorted vision) are what as known as refractive errors. It means that the light which our eyes depend upon to see the things around, is being bent indefinitely by our eyes.
Some of the eye defects can't just be corrected easily by simply using optician eyeglasses. Cataract is an example. It is the clouding that develops in the crystalline lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light. A medical surgery may be needed to treat such defect. There are some cases of cataract where no surgery can ever correct. For doing so might only result to permanent loss of the patient's vision.
Take care of your eyes. If you are feeling something wrong with your eyesight now then you better go and see your doctor. It should never be too late yet.
