Literature Review by Berwyn

Literature Review

Short-sightedness (myopia) is a problem of vision that causes distant objects to appear blurred, while close objects can still be seen clearly.
This is because light rays are being focused in front of the retina (the inside of the back of the eye), rather than directly on the retina.
At least 5 million people in the UK are short-sighted, and about 200,000 of them have high-degree myopia.
Myopia is caused by the eye being too long from front to back, or the cornea (the front of the eye) being too steeply curved. 

Prevention And Cure
Common cures are to wear spectacles and contact lenses which match the degree of your eyes.More methods but risky treatments are Lens Implant Surgery,Orthokeratology lenses,a permanent but risky one is called ‘lasik surgery’.

There is a sum of available treatment for myopia,but most of them are temporary or may hold a risk.This shows that as modern science advance more treatments are available but
more safer and quicker methods must be discovered.
