Blepharitis is a group of ophthalmologic diseases characterized by the development of inflammatory processes in the tissues of the extreme zone of the eyelids.

Photophobia, or photophobia - a deviation characterized by the occurrence of severe discomfort in the eyes caused by artificial lighting of the room.

Amblyopia is not amenable to correction with the help of glasses and contact lenses, does not pass on its own, and most often is a secondary visual impairment. What it is? When amblyopia eyes of a person see different pictures, they are differently involved in the visual process: one eye does not fully see, the brain can not reduce the visual picture in both eyes into one common, as a result, the work of one eye is completely or partially suppressed volume perception of objects, the sequence of their location in space, the sizes of objects are also evaluated inadequately.
Intraocular pressure is called, under which the eye fluid is in the cavity of the eyeball. Ideally, IOP does not change, which forms a stable physiological conditions for all structures of the eye. Normal pressure inside the eyes ensures a normal level of microcirculation and metabolism in the tissues of the eyes.

Glaucoma is a common group of eye diseases that is characterized by a periodic or constant increase in intraocular pressure with the further development of typical visual defects, as well as a gradual decrease in vision and possible atrophy of the optic nerve. The symptoms of glaucoma are manifested by a narrowing of the visual fields, pain, pain and a feeling of heaviness in the eyes, blurred vision, deterioration of twilight vision, in severe cases of blindness.
