Certain vision problems, such as nearsightedness, farsightedness, astigmatism
and presbyopia are considered "refraclive" because they relate to
your eye's ability to properly bend, OR refract, light rays entering the eye.
The proper refraction of light onto the retina creates "normal" eyesight.
Refractive visual problems are measured in units called diopters- they represent
the level of correction needed in lenses to normalize vision. The more nearsighted
or farsighted you are, the higher your prescription in diopters.

Myopia
More than 70 million people in North America (about one in four) are
nearsighted. Myopia is the medical term for "nearsightedness.“
It occurs when your eye is too long in relation to the curvature of your
cornea. Myopia causes light rays entering the eye to focus in front of
the retina, producing a blurred image
The term "nearsighted" means that you can see objects, that
are "near" to you more clearly than distant object. The more
myopic you are, the more blurred distant objects appear, the higher your
prescription in diopters and the thicker your glasses.

Hyperopia
More than 70 million people in North America (about one in four) are
nearsighted. Myopia is the medical term for "nearsightedness.“
It occurs when your eye is too long in relation to the curvature of your
cornea. Myopia causes light rays entering the eye to focus in front of
the retina, producing a blurred image
The term "nearsighted" means that you can see objects, that
are "near" to you more clearly than distant object. The more
myopic you are, the more blurred distant objects appear, the higher your
prescription in diopters and the thicker your glasses. |

Astigmatism
Many patients with myopia and hyperopia have some degree of astigmatism,
or an oval shape, to their cornea. It occurs when your cornea is shaped
more like a football than a basketball. As a result, you experience distortion
or tilting of images due to the unequal bending of light rays entering
your eyes. People with high degrees of astigmatism have blurred vision
for both near and distant objects. |
Presbyopia
Presbyopia is part of the normal process of aging. It develops as the lens
of the eye loses some of the flexibility that characterizes younger eye. Everyone
experiences the effects of presbyopia, typically between the ages of 4O and
50. Nearsighted people who become presbyopic may require bifocals in their forties,
and those who never needed glasses before may require reading glasses.
Mild myopia counteracts presbyopia. That is why, if you're slightly myopic
with presbyopia, when you remove your glasses you may still be able to read.
Laser vision correrction may treat your myopia< but you may need reading
glasses for fine print to correct your presbyopia
