Refractive errors ( myopia, astigmatism and hyperopia)

The commonest causes of vision blurring are refractive errors. The 3 common refractive errors are:

1. Myopia / short sighted. Usually distance vision is blurred but nearer objects are clear.
2. Hyperopia/ Long sighted. Usually near vision is blurred but distance objects may be clearer.
3. There is distortion on the eye surface and all images are slightly blurred.

Treatment methods include glasses, contact lenses and surgery
