What is a Refractive Error?
It occurs when the eye cannot clearly focus the images from the outside world. It causes blurred vision, which is sometimes so severe that it causes visual impairment.
What Is Refractive Surgery?
Refractive surgery includes procedures that help to reduce or eliminate your dependence on glasses/contact lenses.
Types Of Refractive Error :
- Myopia (Short-sightedness)
In this condition the eye is longer than normal, causing light rays to focus in front of the retina. Distant objects appear blur, while nearby objects can be clear. - Hyperopia (Far-sightedness)
In this condition the eye is shorter than normal, causing light rays to focus behind the retina. Near objects appear blur. - Astigmatism (Cylindrical power)
In this condition the cornea is not perfectly round but oval in shape. Hence eye is unable to focus clearly. It is usually seen along with myopia and hypermetropia.
