Myopia (Nearsightedness)
Myopia is a refractive condition where a person can see better up close than they can at a distance. It is primarily caused by a longer eyeball that results in the light entering the eye to focus in front of the retina. Myopia can be corrected by glasses, contacts or refractive surgery.
Hyperopia (Farsightedness)
Hyperopia is a refractive condition where a person can see better at a distance than they can up close. It is primarily caused by a shorter eyeball that results in the light entering the eye to focus behind the retina. Hyperopia can also be corrected by glasses, contacts or refractive surgery.
Astigmatism
Astigmatism is a refractive conditions that can affect a persons vision both up close and far away. It is primarily caused by what is commonly referred to as a “football” shaped eye that results in the light entering the eye to focus in multiple locations around the retina. Astigmatism can also be corrected by glasses, contacts or refractive surgery.
Presbyopia
Presbyopia is a condition that affects a persons ability to focus up close as they age. It is due to a combination of weakening focusing muscles and a hardening lens that occurs as one gets older. Presbyopia may continue to get worse as you get older, but it can be corrected by glasses or contacts. If you are nearsighted to a certain degree, you may be able to just read by taking your glasses off!
