Why am I seeing red lines?
Sometimes you can see squiggly lines, like veins, on the surface of your eye, making one or both eyes appear bloodshot. The redness comes from blood vessels that are dilated as a result of some type of irritation or infection. The numerous causes of red eye include: Allergies.
What is red afterimage?
If you stare at a red object and immediately look at a white area afterward, you will see an afterimage that is the same size and shape, but it is blue-green, or cyan, in color.
What causes color afterimages?
What causes afterimages? Negative afterimages occur when the rods and cones, which are part of the retina, are overstimulated and become desensitized. This desensitization is strongest for cells viewing the brightest part of the image, but is weakest for those viewing the darkest.
Why do I see streaks when I look at lights?

You may have experienced this sensation if you have ever been hit in the eye and see “stars.” These flashes of light can appear off and on for several weeks or months.
What does it mean to see lines in your vision?
Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on your retina. The shadows you see are called floaters.
Why do I see sparkles?
Anatomy of the eye The part of your eyeball directly in front of the retina contains vitreous, a gel-like substance that helps your eye keep its shape. There are also tiny, very thin fibers in the vitreous. When these fibers pull on your retina or the gel rubs against your retina, you may see stars.
Are eye floaters bad?
Even though they can be annoying and bothersome, eye floaters are usually harmless. They usually drift out of your line of sight and you stop noticing them over time. This can be frustrating for people who notice the eye floaters dancing across their view often, but it’s the safest option in most cases.
