Also known as near sightedness, myopia causes blurry vision at distance while vision at near is clear.  This usually results from a long eyeball or too much plus power in the eye.  Myopia is corrected using minus lenses and is one of the most common prescriptions seen.

Also known as far sightedness, hyperopia causes blurry vision at near while vision at distance is usually clear.  This commonly results from a short eyeball or not enough plus power in the eye.  Hyperopia is corrected using plus lenses.

Astigmatism is when the cornea is shaped like a cylinder instead of being perfectly round.  This causes blurry vision at both distance and near.  Astigmatism is corrected using special cylindrical lenses.

Our eyes lose the ability to focus on near objects over time.  This condition is known as presbyopia.  This usually starts at the age of 40. Your optometrist can help determine the optimal lens power needed for you to be able to see near objects clearly.

Glaucoma is an eye disease where high pressure in the eye damages the optic never.  There are many subtypes of Glaucoma including some that have normal pressures.  Your optometrist will determine your risk of Glaucoma by looking at many factors including the eye pressure as well as the appearance of your optic nerve.

The Retina is a clear tissue that lines the back of the eye.  It is responsible for your ability to see.  The Retina sits flush against the back of the eye.  In certain conditions it might detach from the back.  Retinal Detachment is an Emergency.  Your optometrist checks the health of your eye and will determine if you are at risk for a retinal detachment.

The lens focuses light onto the retina.  Over time the human lens becomes cloudy.  This is called Cataract.  Your optometrist can determine if you have a Cataract and if surgery is required.
