About Refractive Errors
In eyes with normal vision, light focuses on the light-sensitive retina at the back of the eye. Once the retina senses light, it converts the light into the image that you see.
In refractive errors, the eyes are unable to focus light on the retina. This results in blurred vision. The solution is glasses or contact lenses. These bend the beam of light so it focuses properly on the retina. This should restore clear vision. Glasses (or spectacles) is the most common ways of correcting refractive errors.
Types of Refractive Errors:
There are three common types of refractive errors in children.
