The function of the eye is to see clearly the objects around us. The inability of the eye to accurately focus the rays of light coming from distance on the retina is called refractive error. This condition may be either because the eye is too short or long in length, or because the cornea or lens does not have the required refractive power
What are the ways of treating refractive errors?
The refractive errors may be treated by either of the following ways:
Glasses: this is the simplest and most popular way of correcting refractive errors
Contact lens: this option is cosmetically much better though the maintenance and cleaning of contact lenses may be cumbersome. There is also a slight risk of infection to the cornea, if the contact lenses are not cleaned properly before use.
Refractive surgeries: these are increasingly becoming popular with the advent of more predictable laser treatments.
