There are many reasons why you may be experiencing yellow spots in your vision. Here are some of the potential causes, but for a proper diagnosis, you should visit an eye doctor.
Nonmedical reasons you see yellow spots
Looking at bright lights
Looking at a bright light and then looking away can cause temporary blindness or the temporary appearance of spots or patterns in your vision. Bright light causes special cells in your retina to become saturated with pigment. Your vision should return to normal after a few seconds or minutes when these cells become unsaturated again.

You may notice this phenomenon when you move from a brightly lit area to a dark one or if you’re exposed to a sudden bright light like a camera flash.
Looking directly into the sun or at extremely bright lights like explosions can cause permanent sight loss.
Rubbing your eyes or putting pressure on your eyes
You may experience spots and random bursts of color in your vision after rubbing your eyes or putting direct pressure on your eyeball. These spots and bursts of color are called phosphenes. Phosphenes should go away after several moments and can appear as spots, bars, or random patterns of colorless or colored light.
They’re thought to appear because direct pressure on your eyeball tricks your retinal cells into thinking they’re being exposed to light.
Researchers can also create phosphenes by stimulating the part of your brain that controls vision with an electrical current called transcranial magnetic stimulation.
Drugs, head injuries, and radiation
Exposure to radiation
People exposed to radiation of their head, neck, or eyes commonly report changes in their vision, including seeing lights that aren’t there and colored spots. Radiation therapy used in cancer treatment is one common way people are exposed to radiation.

About 70 percent of people receiving radiotherapy for melanoma of the eye experience seeing light or colors that aren’t there during the procedure. The appearance of these lights or colors can vary but usually goes away once radiation stops.
Other vision side effects that may occur after radiation therapy include:
- blurry vision
- cataracts
- dry eyes
- loss of eyelashes
- glaucoma
- problems with tear ducts
- retinal detachment
Side effects of some medications and chemicals
Some medications can potentially cause spots or random patterns of light to appear in your vision. Seeing spots or random light patterns are one of the most common side effects of the medication ivabradine, used to treat some adults with heart failure.
Seeing spots and light patterns can also be stimulated by alcohol, hallucinogenic drugs, and other drugs.
Another heart failure medication called digoxin is known to cause vision with a yellow-green tint as a potential side effect.
Head injuries
A sudden force to your head can potentially cause random electrical impulses in the part of your brain that controls vision, called your occipital lobe. Your brain may interpret these impulses as spots or patterns.
Head injuries can also lead to structural damage of your cranial nerves, optic nerve tract, or other parts of your vision system.
Other common vision disturbances experienced after a head injury include:
- double vision
- blurry vision
- decreased peripheral vision
- blindness or partial blindness
- glare and light sensitivity
Vigorously sneezing, coughing, or laughing can also cause you to see phosphenes, possibly due to stimulating the cells in your retina with pressure.
Medical conditions
Migraine with aura

Migraine is a condition that causes reoccurring moderate to severe headaches. An aura is when migraine is paired with sensory changes. About 90 percent of people who experience migraine with aura also see spots, stars, or patterns of light. Other visual symptoms can include:
- blind spots
- lines in your field of vision
- seeing flashes of light
- vision loss
- changes to your vision
Retinal detachment and other retinal conditions
Retinal detachment is when your retina becomes partially or fully detached from the back of your eye. It’s a medical emergency that requires immediate attention. When your retina tears or detaches, your retinal cells may fire and lead you to see random spots or patterns of light and color that can potentially include yellow spots.
Other symptoms of a retinal detachment include:
- floaters (debris in your vision) that appear suddenly
- flashes of light
- blurry vision
- vision loss often described as a shadow moving across your vision
Other conditions that cause damage or inflammation of your retina can also potentially cause you to see yellow spots. Some conditions include:
- a rare form of cancer called retinoblastoma
- diabetic retinopathy
- retina infections
- solar retinopathy (damage from looking at the sun)
Transient ischemic attack (TIA)
A TIA is a mini-stroke caused by the blockage of a blood vessel. If it occurs in a blood vessel leading to your eye, it can cause loss of vision often described as a curtain falling over one eye.
it can cause you to see yellow spots or other patterns of light that aren’t there.
Symptoms can include:
- temporary blindness
- seeing spots or patterns of light that aren’t there
- double vision
- visual hallucinations
- afterimage
Eye melanoma
Eye melanoma is a type of cancer of the eyeball. Typical symptoms include:
- seeing floaters
- dark spots on your iris
- blurry vision
- a change in the shape of your pupil
A 2020 case study describes a person who developed seeing random spots and patterns in his left eye due to melanoma in and around his iris. In theory, it’s possible that some people may see yellow spots.
