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