This is finished by straightforwardly shining light so it enters the eye with the legitimate power for clear vision. A round contact focal point twists light equally toward each path (evenly, in an upward direction, and so forth.). They are normally used to address nearsightedness and hypermetropia.

One way is with toric delicate cheap colored contact lenses that work basically the same way as eyeglasses with tube-shaped revision; a toric focal point has an alternate centering power evenly than upward, and subsequently, can address astigmatism. Another way is by utilizing an unbending gas penetrable focal point; since most astigmatism is brought about by the state of the cornea, inflexible lenses can further develop a vision on the grounds that the
