The Methods For Correcting Refractive Errors
There are many ways to correct the refractive errors that cause poor eyesight.Spectacles
Spectacles are the most common and safest method. They are easy to maintain and manage. However, they can be inconvenient for certain activities and cosmetically unacceptable to some people. They restrict peripheral vision and can interfere with sports and outdoor activities.
Contact lenses
If fitted well and properly worn, contact lenses are safe and effective. They allow for more freedom during sports and outdoor activities, and maximise peripheral vision. However, they can be troublesome to maintain, expensive, and carry a risk of infection.
Refractive surgery
Refractive surgery changes the focusing power of the eye by altering the shape of the cornea, usually permanently. It is also commonly known as laser vision correction, of which LASIK is the most common form.
