What is Refraction?
Refraction is the bending of light rays as it reaches the surface of a different material. In the case of our eyes, light passes through cornea or the curved, clear front surface of the eyes.
What are Refractive Errors?
Refractive errors prompt people to seek help from eye doctors. People experiencing refractive error suffer from blurred vision. This is because the eye is unable to focus light properly.
What causes Refractive Errors?
Eye has features that allow it to refract or focus light. First is its overall length. Second is the curvature of the cornea and third is the curvature of the lens found inside the eyes. Refractive error can be triggered by eye problems. For example, the eye can be too short or long. Or, the cornea’s shape is distorted. It can also be because of the too steep curve in the lens of the eyes.
How is Refractive Error Treated?
Eye doctors run tests to find out which type of refractive error you have. There are instances when a person suffers from more than one type of refractive error and through examinations, the doctors are able to give necessary prescriptions. Glasses and contact lenses can be worn to correct refractive errors. Surgeries may also be performed.
