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 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.
For those ready to scrap conventional, eyeglasses, local eye care professionals will prescribe a brand of contact lenses to vision care patients and direct them to the appropriate retailer.
Acuvue Contact Lenses is the most popular brand around. Acuvue Contact Lenses provides general vision lenses, color contact lenses (with 10 different shades), and astigmatism and multifocal lenses. Acuvue Contact Lenses has also followed a recent trend of
extended wear lenses. Generally, lenses are removed from the eye and set in a cleansing solution overnight, but other kinds of lenses are safe to wear for longer than 12 hours. Extended wear lenses are literally discarded after a certain length of time and replaced by another set.
