Nearsightedness and farsightedness are caused by light falling somewhere other than directly on the retina. Normally, light enters the eye through the lens and shines directly on the back of the eye called the retina. This is important because the retina is where all the receptors are, and they convert the light into nerve signals that are sent to the brain.
In nearsightedness, light comes through the eye and lands in front of the retina, causing images far away to appear blurred. This can be caused by a curvature in the cornea or lens that is misdirecting the light, or by the shape of the eye itself. If the eye is longer than normal, light may fall in front of the retina.
In farsightedness, light falls behind the retina, so that images close up appear blurred.This can also be caused either by the curvature of the lens or cornea, or by the shape of the eye. In the case of farsightedness, the eye may be shorter than normal.
Nearsightedness is called Myopia and farsightedness is called Hyeropia.
Myopia, also known as nearsightedness, is a condition where a person can see nearby objects clearly but distant objects appear blurry. Hyperopia, also known as farsightedness, is the opposite, where distant objects are seen clearly but close-up objects may appear blurry. Both conditions are caused by the way light is focused in the eye, with myopia being due to the focal point falling in front of the retina and hyperopia being due to the focal point falling behind the retina.
Nearsightedness, also known as myopia, is more common than farsightedness, also known as hyperopia.
Yes, a positive meniscus lens can correct myopia (nearsightedness) by converging light rays to focus properly on the retina, improving vision for distant objects. This type of lens helps to move the focal point back to the retina, reducing the blurriness associated with myopia.
Common genetic eye problems that individuals may inherit from their parents include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, color blindness, and certain types of glaucoma and macular degeneration.
Myopia (nearsightedness) is the opposite of hyperopia.
Hyperopia
It is nearsightedness and hyperopia is farsightedness.

The eye is important don't defect it!
it is possible for a person to have both myopia and hypermetropia(hyperopia).The defect can be corrected by using bifocal lens.
Two common eye defects are myopia (nearsightedness) and hyperopia (farsightedness). Myopia is usually corrected with eyeglasses or contact lenses that help focus light correctly onto the retina. Hyperopia can also be corrected with eyeglasses or contact lenses, or in some cases with surgery such as LASIK to reshape the cornea.

Nearsightedness is called Myopia and farsightedness is called Hyeropia.
Hyperopia is the medical term for farsightedness.
Hyperopia, myopia, and diplopia are some medical terms meaning a type of vision.
