Headache was not observed every time when I was suddenly unable to read text.Went to eye doctor,he used light and drops to test eye and confirmed no issues.Went General Doctor,gave some tension headache tab and B12 tablets.After using those,above symptoms gone.But high number of black threads observed. Those only can see in bright light.Went to eye doctor again in another hospital, they used light test (white & blue light) and drops they confirmed that no issues(no retinal tear or hole).

Noproblem at indoor,digitalscreen.Observing especially at roads,sky,white color buildings. Not trees and greens. Please help.

No one can tell you exactly what is causing this, especially  over the internet.  In a young healthy person, by far the most common thing that causes is is "migraine syndrome". Especially if female or on hormones/birth control pills, estrogens or family history of migraine.  It is possible to have migraine syndrome without headache, especially if you are over or near 40 years of age.   Migraine syndrome is an excluding diagnosis which means first you have to rule out disease of the eye, cardiovascular system and central nervous symptom.   Migraine Syndrome and transient ischemic attacks, and certain brain problems can mimic migraine syndrome. Since you have had a normal eye exam,  you will need to work with an internal medicine doctor or neurologist to exclude these other causes.
