Final answer:
Farsightedness, or hyperopia, is a common visual acuity problem where someone can see far objects better than closer objects. In hyperopia, the eye does not converge sufficient rays from a close object to make the rays meet on the retina. This results in blurry vision for close objects but clear vision for distant objects.
Step-by-step explanation:
Farsightedness, also known as hyperopia, is a common visual acuity problem where someone can see far objects better than closer objects. In hyperopia, the eye does not converge sufficient rays from a close object to make the rays meet on the retina. This results in blurry vision for close objects but clear vision for distant objects. The distance to the closest object that can be seen clearly is called the near point of the eye. This condition is caused when the eye does not converge light rays from close objects sufficiently, causing images to be focused behind the retina. To correct this, a convex lens is used to adjust the focus so that images fall properly on the retina. People with hyperopia have a near point that is further than the normal 25 cm, meaning they cannot see close objects as clearly as they should.
