lensesesOver fx 140 million people in the contact United States wear lenseses. People whose lenses eyes have refractive fx and contact errors do not see clearly without glasses, because the light emitted from the objects lenses and fx they are observing does not come into focus on their retinas. For people who are farsighted, images come into contact focus behind the lenses and fx retina; for people who are nearsighted, images come into focus in front of contact the retina. lenses and fx Lenses work by changing the direction of light so that images come into focus on the contact and lenses and fx retina. The greater the index of refraction of the contact and lenses lens material fx and the greater the difference in the curvature between the two surfaces of the lens, the greater the change in direction contact of light that passes through it, and the lenses and fx and contact greater the correction.Lenses can be unifocal, with one correction for all distances, or they can be correct for more than one distance (multifocal). One type of multifocal, the lenses bifocal, has an area of the lens (usually at the bottom) fx that corrects for nearby objects (about 14 in from the eyes); the remainder of the lens contact corrects for distant objects (about 20 ft from the eyes).

They can be worn up to a week. Daily lenses wear lenses are made of plastic that is permeable to oxygen and absorbs water; therefore, they are soft and flexible. These lenses must be removed and cleaned each night, and they do not correct all vision problems. lenses are easier to get used to than rigid lenses, but are more prone to tears and do not last as long. Extended-wear lenses are highly permeable to oxygen, are flexible by virtue of their ability to absorb water, and can usually be worn for up to one week. They fx do not correct all vision problems. There is more of a risk of infection with extended-wear lenses contact than with daily-wear lenses. Extended-wear disposable lenses are lenses worn continually for up to six days and then discarded, lenses with no need for cleaning.
