Really?: I'm not advising 'ways' to harm vision. Your eyes are probably the most precious resource that you have, so protect & take care of them. If you are having vision problems, see an ophthalmologist for an evaluation.

A 47-year-old member asked:

Any possible vision impairments assosiciated with long exposure to black lights in the 60s?

1 doctor answer6 doctors weighed in
Dr. Richard Bensinger
Ophthalmology 52 years experience
Not likely: The overall intensity of black light bulbs was too low to cause any effects on the vision. The intensity of the light was simply enough to cause flurorescent dyes on objects and clothes to shine nicely. Most of these environments had very loud music and the delayed effect on hearing is a much more likely issue.

Brain problem: Cortical visual impairment is when visual function is affected by changes in the brain rather than changes in the eye. Cortical visual impairment can be caused by developmental brain defects, head trauma, strokes to the occipital lobe and some other things.

What are vision impairments and do they get worst?

Form of vision loss: Visual impairment is the loss of vision from some disease, trauma or degeneration that cannot be corrected by glasses, medication or surgery. In the us we use different terms to signify the degree of impairment such as "low vision", "legally blind" and "totally blind". These are defined by how good the best corrected vision is as well as how much of the peripheral vision is intact.

What are the symptoms of cortical vision impairments?

1 doctor answer1 doctor weighed in
Dr. Richard Bensinger
Ophthalmology 52 years experience
Visual field loss: Dysfunction in the cortex either disrupts the visual pathways, blocking that portion of the visual signal--or there can be dysfunction of the actual visual processing portion (occipital lobe). In both cases chunks of vision will be lost . Other cortical problems may disrupt pattern recognition, facial recognition or other higher degree visual interpretation.

No: Except for a few rare conditions which should be identified by the doctor who gave the drops, the drops will wear off and not be a problem.
