Eye floaters are small specks, dots, circles, lines, or cobwebs that appear to float in your field of vision. They are usually harmless and do not interfere with your sight, but they can be annoying. Floaters are caused by changes over time to the vitreous, which is the jelly-like substance inside your eyes that is attached to the retina. As you age, the vitreous starts to thicken or shrink, and clumps or strands can form in it. These clumps cast tiny shadows on your retina, which you see as floaters.

Most floaters are caused by age-related changes, but they can also be caused by other factors, including:

• Eye infections
• Eye injuries
• Uveitis (inflammation in the eye)
• Bleeding in the eye
• Diabetic retinopathy
• Crystal-like deposits that form in the vitreous
• Eye tumors

If you notice a sudden increase in eye floaters, contact an eye specialist immediately, especially if you also see light flashes or lose your vision. These can be symptoms of an emergency that requires prompt attention.

In summary, floaters are caused by changes in the vitreous inside your eyes, which is a normal part of aging. While they are usually harmless, they can sometimes be a sign of a more serious eye condition, so its important to see an eye doctor if you notice new floaters that appear suddenly and dont go away.
