    The Morgan lens can be used in many situations requiring ocular irrigation or the application of medicine to the eye, including cases of chemical eye burns, thermal burns, irritants (e.g., gasoline, detergent), nonembedded foreign bodies, foreign body sensation with no visible foreign body, routine cleansing before eye surgery or eyelid surgery, or for infections.

  3. Optical coating - Wikipedia

  7. Gradient-index optics - Wikipedia

    en.wikipedia.org/wiki/Gradient-index_optics

    The lens of the eye is the most obvious example of gradient-index optics in nature. In the human eye, the refractive index of the lens varies from approximately 1.406 in the central layers down to 1.386 in less dense layers of the lens. [1] This allows the eye to image with good resolution and low aberration at both short and long distances. [2]
