Eyeglasses refract light to correct for problems with the eyes. As the light needs to be bent more, the glass needs to be thicker to make the light bend farther.
A convex lens is thicker in the middle than at the edges. This shape causes light rays passing through it to converge, making it a converging lens that can focus light to a point.
A concave lens is a lens that is thinner at the center and thicker at the edges. It is used to correct myopia (nearsightedness) by diverging light rays before they enter the eye, thus helping to focus the image on the retina. Concave lenses are often used in glasses or contact lenses for people with nearsightedness.
They are convex lenses.
I think it's because of the lens, which is covered by the cornea starts to lose it's ability and shape. and slowly the eyesight becomes annoying.
Concave. The opposite- thick in middle, thin at edges- is convex.
A concave lens is thicker at the edges compared to the center.
In a convex lens, the middle is thicker than the outer rim. In a concave lens, the outside rim is thicker.
A convex lens is thicker in the center. This type of lens bulges outward in the center and is thicker at the middle than at the edges. Concave lenses, on the other hand, are thinner in the center.
A biconvex lens.
A lens that is thicker in the middle than at the edges is called a convex lens. It is a converging lens that causes light rays to converge at a focal point.
it is a convex lens .

Yes, this is a concave lens. It is also called a diverging lens because it causes light rays to spread out.
The convex lens are the converging lens. The periphery of the convex lens is thinner & the center part is thicker. In other words, the convex lens are bulging at the center & thinner at the periphery.
A convex lens is a curved lens in which the center is thicker than the edges. Convex lenses are thicker in the middle and thinner at the edges, causing light rays passing through it to converge at a focal point.
thicker at the edges that in the middle
