You also have a thick jelly substance in your eyes called the vitreous
. In most people, the thick jelly will liquify over time. In high myopes, the liquifaction happens much sooner. This can lead to more floaters and a PVD earlier than normal. A PVD (posterior vitreous detachment) is where the liquified jelly pulls away from the wall of the eyes. Sometimes, it can stimulate the retina and cause the flashes of lights
you see. When you move your eyes quickly, the vitreous swirls around and can precipitate these flashes.
The amount of flashes you see seems to be stable, so no need to worry at this time. You are at increase risk of retinal problems such as tears and detachment.
If you notice a sudden increase in floaters, flashes of light (like a lightening storm), or a shadow/veil in the periphery of your vision, this can be worrisome for a retinal detachment
. You would need to contact your ophthalmologist
promptly in that case.
