Why do I see tiny dots in the dark?

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 keep seeing after images?

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.

The dots are actually white blood cells moving along the fine blood vessels (capillaries) in front of the retina at the back of the eye. This experience is called the ‘blue field entoptic phenomenon‘ because it’s especially noticeable when looking into bright blue light, such as a cloudless sky.

Why do I see sparkles in the air?

Why does it happen? The space between the lens and the back layer (retina) of our eyes is filled by a jelly-like substance called the ‘vitreous’. Over time, this jelly naturally shrinks and separates, leaving small clumps of cells and particles floating in liquid (think of a shaken snow globe).

Are eye floaters normal?

Floaters can come in different sizes and shapes. Some floaters look like small dots, while others appear like threads or little hairy clumps. In most cases, floaters are normal and harmless. However, a sudden increase in their number may indicate damage to particular internal structures of the eye.
