Astigmatism is a very common visual problem which is found in over 30% of patients tested.

It may accompany farsightness or nearsightedness. Although mild astigmatism may be asymptomatic, with higher amounts of astigmatism symptoms may include blurred vision, eye strain, fatigue, squinting, or headaches.

How to correct Astigmatism?

Astigmatism is corrected by using an astigmatic or toroidal lens. If your prescription contains three parts rather than one, your Optician has found some astigmatism in one or both eyes.

A prescription with three parts could look like this:
     -2.75/ -1.25 x 90

The first part: This indicates your main spherical correction.
Part Two: This indicates the extent of the astigmatism in dioptres.
Part Three: This is the axis of the cylinder required to bend certain light rays to compensate for the corneas oval shape.

Hypermetropia - Longsightedness

Far sighted people have difficulty focusing on objects that are up close but may be able to see objects in the distance very well.

What causes Hyperopia?

The eyeball is too physically short, causing light rays to focus beyond the retina. Many children are born with hyperopia and some of them out grow it as the eyeball lengthens with normal growth.

How to correct Hyperopia?

Hyperopia can be corrected by wearing convex lenses. If your prescription has a plus number (+2.50) you will be far sighted.
