Understanding eye disturbances can be crucial for maintaining eye health and recognizing potential issues early on. Let's address your questions one by one, considering the implications of each symptom you described.

1. Flashes of Light After Eating Spicy Foods: Experiencing flashes of light after consuming spicy foods or raw onions may not be directly harmful, but it could indicate a sensitivity that your body has developed. These flashes, resembling camera flashes, could be related to a phenomenon known as "photopsia," which can occur due to various reasons, including retinal irritation or stimulation of the optic nerve. If these flashes are frequent or accompanied by other symptoms like vision changes or headaches, it would be wise to consult an eye care professional.

2. Wavy Distortions in Vision: The appearance of wavy or distorted lines in your peripheral vision, especially when focusing intently on an object, could be a form of visual aura. This is often benign but can also be associated with migraines or other neurological conditions. If these distortions are transient and resolve quickly, they may not be harmful. However, if they persist or worsen, it is essential to seek a comprehensive eye examination to rule out any underlying retinal issues.

3. Light Perception in the Corner of Your Eye: The sensation of light appearing in the corner of your eye while sleeping could be due to several factors, including pressure on the eye or the presence of floaters. This phenomenon is generally harmless, especially if it resolves quickly. However, if you notice this frequently or if it is accompanied by other visual disturbances, it would be advisable to have your eyes checked.

4. Starburst Patterns While Sleeping: Seeing star-like points of light in your vision, particularly when you are about to sleep, can be a benign occurrence, often related to the way light interacts with your retina or the vitreous humor. These are typically not harmful, especially if they are fleeting. However, if you experience them regularly or if they are accompanied by other symptoms, it is important to consult with an eye specialist.

5. Foreign Body Sensation: The feeling of something stuck in your eye, especially if it is accompanied by itching or irritation, could indicate dry eyes, allergies, or even an infection. This sensation should not be ignored, particularly if it persists, as it could lead to more serious conditions if left untreated.

Regarding your question about whether visual disturbances caused by vitreous traction (such as flashes) can be felt immediately or after some time: Typically, if vitreous traction is causing flashes or other visual anomalies, you may notice these symptoms relatively quickly. However, the severity and type of visual disturbance can vary. If the vitreous pulls on the retina significantly, it can lead to more serious conditions like retinal tears or detachments, which may present with sudden changes in vision. Therefore, if you experience any sudden changes in your vision, it is crucial to seek immediate medical attention.

In summary, while many of the symptoms you described can be benign, they can also indicate underlying issues that require professional evaluation. Regular eye exams are essential for maintaining eye health and catching potential problems early. If you are experiencing any of these symptoms frequently or if they worsen, please consult an eye care professional for a thorough examination and appropriate management.
