THE DIFFERENCE BETWEEN SHORT AND LONG -SIGHTEDNESS?
Both short-sightedness and long-sightedness are common conditions which diminish a person's eyesight.
Short-sighted people (myopic) have difficulty seeing objects at a distance.
They favour objects that are closer to them.
Their vision is clear when looking at things up close, but further away objects become out of focus or blurred.
Short-sightedness (myopia) occurs when the distance from the front to the back of the cornea’s curve is too steep.
This forces the light to focus in front of the retina, making objects in the distance appear blurred.
Long-sightedness (hyperopia) is the opposite of this and allows people to see objects clearly at a distance but find it hard to focus on things close to them.
This makes day-to-day activities such as working, reading or watching TV difficult and can result in eye strain. This then produces fatigue and headaches.
Long-sightedness occurs when the distance from the front to the back of the cornea’s curve is too steep.
