Mild short-sightednessMyopia up to -3.00 dioptres
Low long-sightednessHyperopia from +0.75 to +2.50 dioptres

Furthermore, what does it mean if you are long-sighted? Long-sightedness is when the eye does not focus light on the retina (the light-sensitive layer at the back of the eye) properly. This may be because: the eyeball is too short. the cornea (transparent layer at the front of the eye) is too flat. the lens inside the eye is unable to focus properly.

Considering this, what is short sighted vision?

Short-sightedness usually occurs when the eyes grow slightly too long. This means that light doesn't focus on the light-sensitive tissue (retina) at the back of the eye properly. Instead, the light rays focus just in front of the retina, resulting in distant objects appearing blurred.

Can you be short sighted and long-sighted?

Does short sightedness get worse with age?

Depending on the amount of myopia, you may only need to wear glasses for certain activities, like watching a movie or driving a car. Or, if you are very nearsighted, you may need to wear them all the time. Generally, a single-vision lens is prescribed to provide clear vision at all distances.
