We have a very small difference in the visual field of each eye. The blind spots are not recognized when both eyes are open because visual fields of the two eyes overlap. Blind spot can still be challenging to encounter even with one eye closed, subjectively because of the ability brain to ignore the missing portion of the image (Gamm 1). Sclera may be described as the white, outer part of the eye that benefits to maintaining the shape of the eye and to protect the eye from injury. Conjunctiva, which is a clear mucus membrane that helps lubricate the eye, covers the sclera. Three divisions create the sclera; episclera, lamina fusca, and the sclera. The episclera is a loose connective tissue that is located beneath the conjunctive. The lamina
