When i'm wearing white clothes i saw small black spot in my visionbefore it was 3 in my left eye now both have it and have a plenty small black spot?

Vitreous detachment: The gel lining within your eye is separating from retina. Normal part of aging yet should be checked as small black spots may represent blood cells or pigment indicating a tear if not thru the retina then at least abrasion. Tears left untreated can result in detachment and permanent visual loss. Good luck.

Floaters: It sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery.
