Understanding eye flashes and visual disturbances can be quite concerning, especially for individuals with a history of eye conditions like floaters or those who have experienced trauma to the eyes. Let's break down your questions and concerns regarding the phenomena you are experiencing.

1. Understanding the White Light Spots: The white light spots you see, especially when looking at bright backgrounds like the sky or a white wall, can indeed be related to a phenomenon known as "photopsia." This term describes the perception of flashes of light or spots in your vision. While some sources may refer to this as "Schneiderian phenomenon," it is essential to note that this can occur for various reasons, including retinal issues, vitreous detachment, or even migraine aura, even if you do not have a history of migraines. Given your history of eye trauma and floaters, it is crucial to monitor these symptoms closely. If the frequency or intensity of these flashes increases, or if you experience any new visual disturbances, it is advisable to seek a comprehensive eye examination.

2. White Light Spot in the Corner of Your Eye: The sensation of a white light spot in the corner of your eye, particularly if it is not near the nose, could be indicative of several conditions. It may be related to the vitreous gel pulling away from the retina, which can sometimes cause flashes or spots of light. However, it is also essential to rule out any potential retinal issues, especially since you have a history of eye trauma. Since you mentioned that you had a thorough examination of your retina in late August, and everything was deemed normal, it is reassuring. Nevertheless, if this sensation persists or worsens, a follow-up with your eye care provider is warranted to ensure there are no underlying issues.

3. Flashes While Reading: The experience of seeing one or two white light spots while reading, which then disappear, can also be attributed to several factors. This could be related to eye strain, especially if you are reading for extended periods without breaks. Eye strain can lead to temporary visual disturbances, including flashes or spots of light. However, it is also essential to consider that this could be a sign of changes in the vitreous or even early signs of retinal issues, particularly in someone with a history of floaters and eye trauma. If these flashes occur frequently or are accompanied by other symptoms, such as a sudden increase in floaters, blurred vision, or a shadow in your peripheral vision, it is crucial to seek immediate medical attention.

In summary, while some of the phenomena you are experiencing may be benign and related to eye strain or the normal aging process of the vitreous, your history of eye trauma and floaters necessitates a cautious approach. Regular eye examinations and open communication with your eye care provider are essential in managing your symptoms and ensuring your visual health. If you notice any changes in your symptoms or if they become more frequent or intense, do not hesitate to seek further evaluation. Your vision is vital, and staying proactive about your eye health is the best course of action.
