contact lenses are concave because their sides curve inward
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 can be either. They will converge if thicker in the middle than edges, and diverge if thinner in the middle than edges.

Angle of contact is the angle between a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute . For convex surface , it is obtuse.

Convex lenses are thicker in the middle then the edges and concave are thicker at the edges then the middle. When light travels through lenses, refraction occurs. The light bends either outward or inward, it depends on the lens.The lens of your eye is a double convex lens. Its job is to focus the image on the retina of the eye. If one is farsighted, the lens in the eye causes the focus to be behind the retina. These people see far but have some difficultly seeing close-up.To correct this farsightedness, the person would wear glasses or contacts with convex lenses, for It is often used for close examination of small objects.
yes, they are. Contact lens back surface isn't important for the dioptric power; the frontal sourface replaces the frontal sourface of the cornea. So the light angle of incidence is modified and the light focalize correctly on the retina.
Contact the manufacturer and give them the serial number. They may be able to give you the combination or a master combination.
This is a deeply concave surface, often referred to as the base of the lung. It rests on the convex dome of the diaphragm. The concavity is deeper in the right lung because of the higher position of the dome. Laterally and posteriorly, the diaphragmatic surface is bound by a thin sharp margin that projects into the costodiaphragmatic recess.
Miophia is a misspelling of myopia, which is nearsightedness. Myopia is corrected with eyeglasses, contact lenses, or refractive surgery like LASIK. It is important to have regular eye exams to monitor and manage myopia effectively.
