Since two years ago I have a red film in my field of vision when the sunlight (or a white spot) is at the border (or even lightly behind) of the vision field, the red color is especially obvious at the shadows or dark places (it seems logical that the film color is more visible where there is less light). My eye doctor recently diagnosed a little bit opalescence of my eyes, that is, a beginning cataract.
So my question is simple : does cataract condition cause a red film when sun is shining at the vision field border ?
I have an explanation for this : at the eye border the white sun light goes trough the skin and is colored red by the blood, then because of opalescence the red light propagates into the whole vision field, thus creating a red film. So if this explanation is correct then any people with a cataract condition should see a red film in such situation, that is what I want to check. Should be quite simple.
(Without strong spots there is still a mild gray film, making black appearing grayish and making shades differences less obvious to see than before this condition. Vision tests on green or red background doesn't make any differences)
