Nearsightedness:
Nearsightedness or myopia occurs when the cornea is too steep relative to the length of the eyeball. As light enters the eye, the visual image comes to a focus in front of the retina, resulting in a defective, blurred or distorted view of distant objects.

Farsightedness:
Farsightedness or hyperopia occurs when the cornea is too flat relative to the length of eyeball. As light enters the eye, the visual image focuses behind the retina resulting in a defective, blurred or distorted view of both close and distant objects.

Astigmatism:
Astigmatism is a condition that occurs when an eye is shaped like a football instead of the rounder, basketball shape of a normal eye. The irregular shape of the cornea results in two focal points, or blurred vision. The uneven bending of light rays entering the eyes causes this distortion.

Presbyopia:
Presbyopia occurs as a result of the inability of the eye lens to focus incoming light. The focusing lens becomes unable to change shape and focus on close objects. This results in blurred vision at a reading distance, as well as eyestrain. Presbyopia most often develops in people in their forties.

Amblyopia:
Amblyopia, is a condition when vision in one eye is significantly worse than the other. The diminished sight in the one eye is not an eye disease but is uncorrected vision in an eye with a large spectacle prescription or a lazy or strabismic eye. |

Strabismus:
Strabismus, called lazy eye, occurs when one or both eyes turn and are not working together. This can be a cause of amblyopia. |
| |
Binocularity:
Binocularity, or eye teaming, is the process in which both eyes work together to form one image in the brain in order to avoid double vision or other reading difficulties. Eye teaming may occur because of focusing problems, strabismus or amblyopia. |

Cataracts:
A cataract is the clouding of the eye's lens. The cloudy lens blocks the passage of light through the eye. As a result, the image that reaches the retina and is sent to the brain is cloudy and vision is poor. It is a result of the natural aging process. Certain medications and ultraviolet light can also cause cataracts to develop. Cataracts are the leading cause of poor vision in adults.

Glaucoma:
Glaucoma is a disease that damages the optic nerve and is one of the leading causes of blindness. It occurs as a result of an overproduction of aqueous fluid or when the drainage system becomes blocked, causing fluid pressure to increase. The high pressure causes damage to the optic nerve, resulting in permanent vision loss. Congenital glaucoma presents noticeable symptoms in an infant such as enlarged eyes, cloudy cornea, light sensitivity and excessive tearing. Clarkson Eyecare has the technology for early detection of Glaucoma.
Those at greatest risk include:
• People over the age of 40
• African-Americans (particularly those over 35 years old)
• Anyone with elevated intraocular pressure
• People with a family history of glaucoma, including family members of known glaucoma patients
• Diabetics
• Long-term steroid users

Macular Degeneration:
Macular degeneration causes distortion and loss of central vision and is the leading cause of blindness. The breakdown of the macula, the central focusing portion of the retinal tissue, is the underlying cause. It is commonly a natural result of the aging process and has been linked to ultraviolet light exposure.
