What else can I help you with?
When a person is far sided do the need a concave lens or convex lens?
A person who is farsighted needs a converging lens, which is a convex lens, to help focus light properly onto the retina. This type of lens helps to converge incoming light rays so that distant objects can be seen more clearly.
What type of lens is needed to correct hypermetropia?
Hypermetropia is corrected with a converging lens, specifically a convex lens. This type of lens is thicker in the middle and helps to focus light rays onto the retina, correcting the vision problem associated with hypermetropia.
What happens when concave and convex go together?
When concave and convex surfaces come together, they form a lens. The interaction of these two surfaces causes light to either converge (convex lens) or diverge (concave lens), which can be used in various optical devices like cameras, telescopes, and eyeglasses to focus or correct vision.
Does a convex lens help you if you are farsighted?
Yes, a convex lens can help correct farsightedness by converging light rays to focus on the retina, improving close-up vision. The lens bends light towards the center, allowing the eye to focus properly and see objects up close more clearly.
How does a convex affect light rays?
A convex lens causes light rays to converge, meaning they are brought together and focus at a point known as the focal point. This type of lens is commonly used to magnify objects and correct certain vision problems.
Is a fish-eye lens convex?
Yes. Because convex lens produce real image.. so Fish eye has convex lens

What is a convex and a concave lens?
CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.

What lens is used in longsightedness?
Convex lenses are used to correct longsightedness (hyperopia) by helping to focus light onto the retina, which improves near vision.
Is your eye lens concave or convex?
The eye lens is convex in shape, which allows it to focus light onto the retina at the back of the eye, enabling clear vision.
How convex lenses correct farsightedness?
Convex lenses used to correct farsightedness adjust the way light rays enter the eye, helping them to focus properly on the retina. The lens converges light before it reaches the eye's lens, allowing the image to be focused correctly on the retina, improving vision for individuals with farsightedness.
If you want to correct farsightedness you should choose a lens that is what?
To correct farsightedness (hyperopia), you should choose a lens that is convex, meaning it is thicker in the center and thinner at the edges. This type of lens helps to converge light rays before they enter the eye, allowing for clearer vision at close distances. Convex lenses are designated with a plus (+) power value, indicating their magnifying effect.
Is the lens in a human eye concave or convex?
The lens in a human eye is biconvex, meaning it is convex on both sides. This shape allows the lens to converge incoming light rays and focus them onto the retina, which is essential for clear vision.
