Contact lenses are small, optical, often soft, and remarkably thin lenses placed in the cornea of one’s eye. They improve the vision, and sometimes the physical appearance, of eyes. Contact lenses are usually an alternative to traditional eyeglasses, correcting a person’s vision without requiring them to wear ugly, awkward bifocals. However some people with naturally good eyesight still wear contacts, solely for cosmetic reasons - to enhance or change the color of their eye. Unlike eyeglasses, contact lenses are not easily affected by weather, are not especially fragile, and actually (in most cases) do a better job at improving a person’s eyesight. Not to mention, a glasses’ framing immediately hinders a person’s field of vision! This is not so with contact lenses that fit directly onto the eyeball and are practically invisible.
