Why do I see spots when I look at a light?
It’s because of something called photo-bleaching and it happens to the cells in your retina which is the light sensitive bit at the back of your eye.
It’s worth noting actually that the retina is less active when light shines on it than in the dark.
It’s in fact deactivated by light rather than activated by light.
What does it mean when you see sparkles in your vision?
Migraine headaches can cause changes in vision, including seeing stars, sparkles, or flashes. They can also cause spots, heat-like waves, tunnel vision, or zigzagging lines. Retinal disturbances or decreased blood flow to the retina may cause these symptoms.
What happens if you stare at a light too long?
With enough damage to the retina, though, staring at the sun can leave you partially blind. Permanent, complete blindness can also occur from staring at the sun over the long term. The eye’s lens can be damaged from too much UV light, typically resulting in cataracts and invasive tissue growth known as pterygium.
What causes dizziness and seeing spots?
Dizzy spells are common and can be caused by dehydration or low blood sugar. However, there are instances in which dizziness occurs as a result of certain diseases. The cause of balance disorders can be related to health conditions, medications, or a problem in the inner ear or the brain.
