What is Refractive Error in eyes?
Refraction is defined as a change in the direction of light when it passes from one medium to another. This bending of light occurs when light rays pass through the cornea of the eye ( which is the transparent circular portion in the front of the eye ). The light is then focused on the retina and retina converts the light rays into messages that are sent through optic nerve to the brain.
A refractive error usually occurs when the shape of the eyeball prevents light from focusing directly on the retina of the eye. Usually, this happens, due to the length of the eyeball, either shorter or longer, changes in the shape of the cornea or aging of the lens can cause a
What are the most common symptoms of Refractive Errors?

What are the different types of Refractive errors that can occur?
The most common types of Refractive errors are Myopia, Hyperopia, Astigmatism and Presbyopia.
- Myopia: Myopia or nearsightedness is a condition where objects up close appear clearly whereas objects far away appear to be hazy. In myopia, the light refracts in front of the retina instead of falling on the retina.
- Hyperopia: Hyperopia or farsightedness is a condition where the objects up close appear blurred whereas objects far away appear to be clear. In Hyperopia the light refracts to converge behind the retina instead of falling on the retina
. Astigmatism : In this condition, the eye doesn’t focus on light evenly onto the retina. This causes images to appear blurry or stretched out.- Presbyopia: This is an age-related condition in which the ability to focus up close becomes difficult and is a common occurrence in the wider population after the age of 40 years.
