7 Signs You May Have Glaucoma

6. Seeing Rainbows Or Halos

Due to the buildup of fluid in front of the eye, people with glaucoma might see rainbows or halos when looking at lights, especially at night. This can make driving a dangerous task. If bright lights, dim lights, or any lighting causes the appearance of halos, rainbows, spots or "ghosts," seek immediate treatment. Avoid drinking at night as this might increase the risk of accidents due to the inability to focus when headlights from other vehicles or stoplights cause vision problems.
