Hyperopia or hypermetropia,commonly known as being farsighted or longsighted  is a defect of vision caused by an imperfection in the eye  causing difficulty focusing on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves toward the eye, the eye must increase its optical power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred.

hypermetropia- it Is an inability to see near by objects clearly because image is formed behind the retina . also known as long-sightedness


it can be corrected by putting convex lens in front of eye
