i think it's called fish-eye lens
A convex lens curve outwards and has a shape similar to a portion of a sphere. This type of lens converges light rays to a focal point, making it suitable for magnifying objects in microscopes.
a shape of a lens is curved outwards and concave one are curved in wards
convex
A plano-concave lens is a type of lens that has one flat surface (plano) and one concave surface that curves inward. It causes light rays to diverge after passing through it, making it useful for applications that require spreading out light, such as reducing the intensity of a beam.
To clean microscope lenses, use a specialized lens cleaning solution or a mixture of distilled water and isopropyl alcohol on a lens cleaning tissue. Gently wipe the lenses in a circular motion, starting from the center and moving outwards. Avoid using regular cleaning cloths or tissues, as they may scratch the lens surface.
A convex lens curves outwards from the middle. This type of lens converges light rays towards a focal point, commonly used in magnifying glasses and cameras.
A convex lens bulges outwards and causes light rays to meet or converge at a focal point. This type of lens causes parallel rays to be focused down to a point.
A concave lens is thinner in the center. This type of lens curves inward, causing the center to be thinner than the edges.

A convex lens bulges outwards in the middle and converges light rays to a focal point, making it a converging lens. On the other hand, a concave lens curves inwards in the middle, causing light rays passing through it to diverge, making it a diverging lens. They have opposite effects on how light rays are refracted.

A concave lens curves inward and is thinner at the center than at the edges. It diverges light rays and can correct nearsightedness.

convex
A concave lens is thinner in the center than at the edge. This type of lens curves inward, causing it to be thicker at the edges and thinner in the center. It is used to correct myopia or nearsightedness.
A magnifying lens is typically a convex lens. This type of lens is thicker in the center than at the edges, causing light rays to converge in a way that magnifies objects when viewed through the lens.
