Our eyes allow us see by taking in light and processing it into signals to our brains. The light is refracted (bent) by the eyes in this process. If the refraction is not perfect, then our vision is impaired.
There are three types of eye refraction errors:
- myopia (nearsighted)
- hyperopia (farsighted)
- astigmatism (uneven refraction)
Myopia is where the eyes bend incoming light rays too much, causing nearby objects to be clear, but distant objects appear blurred. By wearing glasses, we move the eye’s focus point farther away, allowing us to see far away items more clearly.
