What Are Refractive Errors?
Wondering why your eyes cannot focus on images? It’s due to the irregularity of their shape that leads to blurry vision.
Myopia (nearsightedness)
If you have this, you see better up close while distant objects appear blurry. Recognizing your friends’ faces from far away can be challenging until they’re right in front of you.
Hyperopia (farsightedness)
Seeing objects at a distance is easier than perceiving them when they’re closer. If you have this, reading words at the other end of the room during meetings is effortless compared to reading them near you.
Presbyopia (loss of near vision with age)
As you get older, you can develop this specific type of farsightedness. It typically develops once you reach older than 40. That’s why the need for reading glasses as you age makes so much sense.
Astigmatism
Whether up close or at a distance, objects appear blurry. It is due to the football-like shape of your eyes instead of them being round. Thus, light entering your eyes bends or distorts more than it should.
