VISION BIOPHYSICS: GLAUCOMA, ASTIGMATISM AND MYOPIA

Abstract

About 2.2 million people worldwide are blind due to vision problems related to myopia (25%), astigmatism (70%) and glaucoma (2%). Vision, like hearing, is part of the sensory system, which places those who have it in relation to the world around them, being active by the synapses of the brain and projected by the eyeball. According to articles published by American Health Companies, vision problems occur more frequently in adults over 40 years of age and with a predisposition in blacks due to excess pigmentation. The objective of the present work is to verify, through a structured questionnaire, what type of relationship exists between the aforementioned diseases (glaucoma, astigmatism and myopia) with the skin color and age of each individual. With this work, we aim to contribute to studies about this relationship, since there are few researches related to the biophysics of vision.
