the Red Circle Phenomenon When Closing Your Eyes - Ophthalmology

More Info

---

The phenomenon you are experiencing, where you see a red circle or a similar visual effect when your eyes are closed, can be attributed to several factors related to the visual system and the way our eyes and brain process light and images. This experience is not uncommon and can occur for a variety of reasons.

Firstly, when your eyes are closed, they are not completely devoid of light. Some light can still penetrate through the eyelids, especially if you are in a well-lit environment. This light can stimulate the photoreceptors in your retina, leading to visual sensations even when your eyes are shut. The brain interprets these signals, which can sometimes manifest as shapes, colors, or patterns, such as the red circle you described.

Another possible explanation for seeing a red circle could be related to the phenomenon known as "phosphene." Phosphenes are the visual sensations that occur when pressure is applied to the eyes or when the retina is stimulated in ways other than light. For instance, if you rub your eyes or if there is some form of internal pressure, you might see flashes of light or colored shapes. This could explain the movement of the red circle you perceive as it shifts or fades away.

Additionally, the visual system is quite complex, and the brain often fills in gaps in visual information. When you close your eyes, the brain may create visual experiences based on memory or previous visual stimuli. This can lead to the perception of shapes or colors that are not actually present.

If you are experiencing this phenomenon frequently and it is accompanied by other symptoms such as pain, discomfort, or changes in vision, it is advisable to consult an eye care professional. They can perform a thorough examination to rule out any underlying conditions that may require attention.

In terms of your overall eye health, it is essential to maintain proper eye hygiene and care, especially if you wear contact lenses. Ensure that you are following the recommended guidelines for lens wear and care to prevent issues such as dryness, irritation, or infections, which can also contribute to visual disturbances.

In conclusion, the red circle phenomenon you are experiencing when your eyes are closed is likely a benign visual effect caused by light perception and the brain's interpretation of visual stimuli. However, if you have concerns or if the phenomenon changes in nature or frequency, seeking professional advice from an eye care specialist is always a prudent step. Regular eye check-ups are essential for maintaining eye health, especially if you have any pre-existing conditions or if you wear contact lenses.
