+Detecting Vision ProblemsOptometrist: a professional trained to provide eye and vision care.There are 3 common vision problems which are nearsightedness, farsightedness, and astigmatism.

+Detecting Vision ProblemsNearsightedness: People can see nearby objects clearly, but not faraway objects. It is caused by an elongated eyeball.Farsightedness: People can see faraway objects clearly, but nearby objects appear blurry.Astigmatism: People who have distorted vision. Images do not focus correctly on the retina caused by an uneven curvature in the cornea lens.

+Detecting Vision ProblemsOptometrists may also check for colorblindness and night blindness.Colorblindness: the inability to detect one or more colors. Occurs when a person is born with a deficiency in one or more sets of cones. This disorder is usually inherited.

+Detecting Vision ProblemsNight blindness: is the inability to see well in dim light due to poorly functioning rods. This condition also can be inheritedIt can also be caused by a lack of vitamin A.

+Treating Eye DiseasesAs a person ages, the eyes become susceptible to several diseases.Glaucoma: Age and certain diseases, such as diabetes and high blood pressure, may slow the drainage of liquid form the eye.The result leads to a buildup of pressure in the eye.Glaucoma can damage the optic nerve and lead to sight problems.

Glaucoma often develops so slowly that a person may have severe vision damage before it is detected.Regular eye exams can detect glaucoma before symptoms are noticed.

+Treating Eye DiseasesCataractsThe clouding of the eyes lens.It is very common among older adults.Treatment involves surgical replacement of the clouded lens with an artificial lens.Wearing sunglasses with UV-ray protection and not smoking are two behaviors that may slow or prevent the development of cataracts.

+Treating Eye DiseasesMacular DegenerationIt is the leading cause of eyesight problems in older adults.It occurs when cells in the center of the retina break down.Treatment for macular degeneration is limited and often depends on the extent of the damage

+Treating Eye Infections2 Common eye infections are Sties and Conjunctivitis.Sty: is a painful swelling that occurs when an oil gland at the base of an eyelash becomes infected.

Allergic reactions or infections related to colds can lead to conjunctivitis, an inflammation of the outside layer of the eye.The eye may ooze a yellowish fluid and become red and itchy.Sties and conjunctivitis can be treated with prescription medications
