A how to save a photo film?

An our eyes,like a photo apparatus ,where role for objective are doing cornea and lens, and a light sensitive film is retina, on which sowing all, what we are to see.And from a quality this film and vision depends, thus a diagnosis as detachment retina is very serious ,than sometimes thinking , whom putting his , let s talk about this detailed.

An eyeball covering are three membranes as external is white sclera and transparent cornea, middle is vessel layer.

As inside retina is  is nerve tissue, as covering eyes from inside and in her are difference get ten layers as pigment and attaching to him as calling a layer of sticks and ones are different forms of cells photoreceptors  as which  perceive color and transfer visible signs in a vision brain center .As in healthy eyes membranes are tighter lie between itself, and in story's between a  layer a photoreceptors and pigment layer is filling liquid and in exult of which happening as retina detachment , destroy metabolism  between tissues and vision loosing, but why this is happening? As acute case is eye injury, and detachment display right away or in a few time or in a few years  since injury and injury kinds are detachment retina as complication after a eye surgery , as very bad are eyes injury in optic eye as in a high myopia eyeball changes form , membranes are stretching and tie between theirs is bad. As retina here is thin, as very easy detachment of her breaking  as fast jumps, head incline down, or loading in heavy bag raising and this is regmatogenic as rheumatologist  break retina. 

TRaction detachment is so straining her by adhesions of gel forming substance as filling an eyeball from inside as in diabetic retinopathy, as non inflamed  damage retina eye membrane as retinopathy of pre matures .

Exudative retina detachment as liqiuid of entering under her a vessels and displaying in biological aging of organism, metabolism bad in hypertension,  vessel diseases and other chronic processes.
