Understanding eye flashes, particularly the phenomenon of seeing white light in your vision, can be quite concerning, especially if you're experiencing it frequently or in a way that disrupts your daily life. Based on your description, it sounds like you are experiencing a type of visual disturbance that can be associated with several underlying conditions, particularly in the context of your existing eye issues such as myopia and floaters.

Eye flashes, or photopsia, are often described as brief bursts of light that can appear in various forms, such as spots, streaks, or even flashes resembling lightning. These flashes can occur in one or both eyes and may be triggered by various factors, including movement of the vitreous gel within the eye, which can tug on the retina. This is particularly common in individuals with myopia or those who have experienced changes in their vitreous humor, such as liquefaction or detachment.

In your case, the flashes of white light you see as you are falling asleep could be related to a few different phenomena. One possibility is that these flashes are indeed related to the vitreous gel pulling on the retina, which can happen more frequently when you are in a relaxed state or transitioning between wakefulness and sleep. This is often benign, especially if you have had a thorough eye examination that ruled out any retinal tears or detachments.

Another consideration is that the flashes could be a result of a phenomenon known as "phosphene," which is the perception of light without light actually entering the eye. Phosphenes can be triggered by pressure on the eyes, sudden changes in light, or even the natural activity of the retina as you transition into sleep.
It's also worth noting that the frequency and intensity of these flashes can vary widely among individuals. If the flashes are infrequent and do not coincide with other symptoms such as significant vision loss, it may not be a cause for alarm. However, if you notice an increase in frequency, changes in the nature of the flashes, or if they are accompanied by other symptoms such as floaters, shadows, or a curtain-like effect in your vision, it is crucial to seek immediate medical attention. These could be signs of more serious conditions, such as retinal detachment, which requires prompt treatment.

In summary, while the flashes of white light you are experiencing as you fall asleep may be benign and related to normal physiological processes, it is essential to remain vigilant. Regular eye examinations, especially given your history of myopia and floaters, are important to monitor any changes in your eye health. If you have any concerns or if your symptoms change, do not hesitate to consult with your eye care professional for further evaluation and reassurance.
