How to solve farsightedness using physics
“How can we correct farsightedness using scientific knowledge?”
Although not as pervasive as near-sightedness, far sightedness is becoming an increasingly common problem, with 5-10 percent of Americans experiencing such a diagnosis. Nearsightedness, also known as hyperopia, is caused when the focal length of an individual’s eyeball is too large, causing the incoming light rays to focus on a point behind the eye (Make a link to how images form in the eye), which in turn will cause a fuzzy image. To correct this, we can insert a positive lens in front of the eye of an individual, which will cause the light to refocus at the back of the eye, enabling normal sight.
