Different Color Blobs & Shapes in Vision

Seeing black spots or colors in your vision can be frightening, but there may be a number of causes, some of which are harmless.

Black Spots

Black blobs and shapes in your vision, particularly in one eye only, may be a sign of a retinal detachment, a condition that can cause permanent vision loss if left untreated. Detachments may occur suddenly if you are hit in the eye, but they can happen for no apparent outward cause as well.

If you see colors and colorful spots in your vision that seem to stay around the edges, you may be experiencing a visual migraine. These may accompany or precede a headache or migraine, but they may happen alone as well. Typically, these visual migraines will last 5 to 10 minutes, then disappear with no lasting effects.

Diagnosing the Problem

You should contact your eye doctor if you experience any loss of vision or changes to your vision. He, or his staff, will check your vision and the pressure in your eyes, then dilate your pupils with special drops. This will allow him to look inside your eye and determine the cause of the change in your vision.

Treatment will depend on the cause for the colorful blobs in your vision. If you experienced a visual migraine, there are no treatments, but there are also no residual effects. If you have a retinal detachment, you will be referred to a retinal specialist for surgical repair.


The only way to know what the colorful blobs and shapes in your vision mean is to have an eye doctor examine your eyes when they are dilated. Contact your eye care provider immediately if you have concerns about changes in your vision.
