A positive lens is also called a magnifying lens. It has convex surfaces and it has a measureable focal length where it produces an inverted image of a distant object. The power in dioptres is the reciprocal of the focal length in metres.

A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
A lens with a negative focal length diverges light rays and creates virtual images, while a lens with a positive focal length converges light rays and forms real images.
Cornea/lens.
The lens with the greatest (positive) curvature. The lens with the highest diopter.
The focal distance of a convex lens is always positive. It is the distance between the lens and the focal point when light rays are parallel and converge after passing through the lens.
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
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.
Lens flexure refers to the bending or deformation of a lens due to external forces or pressure applied to it. This can impact the performance of the lens, leading to changes in focus or image quality. Proper handling and care are essential to prevent lens flexure.
A positive meniscus lens has a curved shape that causes light to converge, making it useful for focusing and magnifying images. Its unique optical properties include reducing spherical aberration and increasing depth of field. Applications of a positive meniscus lens include camera lenses, microscopes, and telescopes.
Eyepiece Lens or Ocular Lens is the lens on top. This is use to see the things or objects to observe or to study.
