This bibliographic review work is pointed to the effects of altitude hypoxia on sight. It intends to contribute for the identification of signs and symptoms of hypoxia during high altitude exposition. The understanding of the terrestrial atmosphere and the laws of physics related to gas behavior under atmospheric pressure variation are very important for the correct diagnosis of the dysbarisms, hypoxia, decompression disease and others, by the aerospace health professionals. The atmospheric environment that pilots are exposed is able to interfere in a significant way on visual function and can lead to reversible or irreversible lesions such as: retinal bleeding, decrease of the night vision and vision acuity, restriction of the visual field, emergence of latent strabismus, decrease of the intra-ocular pressure and refractive alterations in individuals that went through refractive surgery.
