Ocular phosphenes are a visual phenomenon or sensation that consists of perceiving a kind of twinkling or points of light. In most cases they occur when rubbing the eyes or closing them tightly and are due to the pressure we exert on the retina, which causes the activation of the photoreceptors.

Why do I see little lights?

RESPONSE. Seeing lights or lightning can be a warning sign of a possible retinal detachment, but it does not necessarily have to be the case. The lights are produced by a mechanical effect in which the vitreous pulls on the retina. It usually occurs in cases of posterior vitreous detachment (PVD).

What causes myopia and astigmatism?

When light rays are not focused at the correct point, we can have blurred vision when looking at objects far away (nearsightedness), near objects (farsightedness), or both (astigmatism). Refractive errors are the main cause of blurred vision, affecting up to 50% of the population in some places.
