How do people with contacts see?

Glasses or contact lenses correct vision because they allow the eye to focus light in the right spot on the retina — the spot that produces the clearest image. Because everyone’s eyes are different, a pair of glasses that makes one person see wonderfully may look terribly blurry to someone else.

What disorder would cause someone to wear glasses or contact lenses to see up close only?

Nearsightedness, or myopia, as it is medically termed, is a vision condition in which people can see close objects clearly, but objects farther away appear blurred. Myopia occurs if the eyeball is too long or the cornea (the clear front cover of the eye) is too curved.

What does a person with contact prescription See?

On a contact lens prescription, you’ll find the same listing of power under OD and OS, and some of the same information you’d see on an eyeglasses prescription. In addition, however, a contact lens prescription will include the prescribed brand, as well as numbers following the abbreviations BC and Dia.

Are contact lenses visible?

Contact lenses, other than the cosmetic variety, become almost invisible once inserted in the eye. Most corrective contact lenses come with a light “handling tint” that renders the lens slightly more visible on the eye. Soft contact lenses extend beyond the cornea, their rim sometimes visible against the sclera.

What is the power in contact lenses?

PWR, power, is the amount of correction the lens must provide to bring vision to an acceptable level; the farther the power is from zero, the more nearsighted or farsighted one is. ADD, added power, is similar to regular power except it will have the opposite sign and is used only in bifocal contact lenses.

Who specializes in diagnosis and treatment of eye diseases and disorders?

What is an ophthalmologist? An ophthalmologist is a medical or osteopathic physician who specializes in the medical and surgical care of the eyes and the prevention of eye disease. An ophthalmologist diagnoses and treats refractive, medical, and surgical problems related to eye diseases and disorders.
