It can be warped in a number of ways to correct for distortions of the optical system. The focal size of the human eye is 23 mm. The refractive index of the retinal picture tool is 1.33, making its effective focal length regarding 17 mm. The retinal photo medium is denser than the air medium, subduing the diffraction impact and leading to a smaller Airy disc. Its diameter is 2.44 lF/n. However, it is not completely clear exactly how the retinal photo medium works. The cornea is one of the most integral part of the eye and also adds to two-thirds of the optical power of the eye. It is practically round, with an outer span of curvature of 8 mm. The cornea’s refractive power is 43 dioptres. The centerpiece of the eye is repaired, however the curvature of the lens varies. This curvature permits the eye to change its focus in a way that makes aesthetic objects more clear. The ball number on the prescription card stands for the lens power needed to remedy the eye’s vision.

Flexible optics retinal imaging (AO-OCT) can be utilized to produce an unique technique for screening for AMD and also to monitor the healing effects of different prevention techniques. Adaptive optics can also be used to establish analysis tools for examining xanthophyll pigments sitting and also can help to recognize the results of lutein supplementation.
