What lenses would you use for short sightedness and long sightedness?
For short-sightedness (myopia), concave lenses are used to diverge light before it reaches the eye, helping to focus the image correctly on the retina. For long-sightedness (hyperopia), convex lenses are used to converge light before it reaches the eye, assisting in bringing the image into focus on the retina.
Can the same lens be used to correct both short sightedness and long sightedness?
Yes, a lens can be designed to correct both short-sightedness (myopia) and long-sightedness (hyperopia) depending on the specific prescription needed. These types of lenses are called multifocal or progressive lenses, which have different sections to correct vision at different distances.
What type of lens is used to correct long sightedness?
Convex lens is used to correct long sightedness (hyperopia). This lens helps to converge the light rays entering the eye, allowing the image to focus correctly on the retina.
How does concave lenses reduce long sightedness?
Concave lenses help reduce long-sightedness by diverging light rays before they reach the eye, allowing the eye to focus the image properly on the retina. This helps correct the refractive error that causes distant objects to appear blurry to individuals with long-sightedness. By providing the additional focusing power needed, concave lenses help bring distant objects into clear focus.
How does the eye respond to light rays to manifest long sightedness?
In long-sightedness, or hyperopia, the eye focuses light behind the retina due to a shorter than normal eyeball or a less curved cornea. This results in difficulty seeing close objects clearly. The eye can compensate by altering the shape of the lens to focus the image correctly on the retina, or by over-focusing, which can cause eyestrain and headaches.

gadha is also called short sightedness
What are the differences between long-sightedness and short-sightedness, and how do they affect one's vision?
Long-sightedness, also known as hyperopia, occurs when the eye is unable to focus on nearby objects. Short-sightedness, or myopia, happens when the eye struggles to see distant objects clearly. Long-sightedness can cause blurry vision up close, while short-sightedness results in blurry vision far away. Both conditions can be corrected with glasses or contact lenses.
