Why Do I Feel a Sparkling Light in One Side of My Eye?

Feeling a flash of light in one side of the eyes may be caused by poor sleep, excessive eye use, vitreous traction on the retina,视神经系统 diseases, and other conditions. Treating the symptoms is conducive to promoting eye health.

1. Poor Sleep: Staying up late for a long time and having poor sleep quality can prevent the eyes from getting adequate rest, affecting eye blood circulation and leading to the symptom of flashing lights in one side of the eyes. Most people can alleviate this by taking appropriate breaks and ensuring sufficient sleep.

2. Excessive Eye Use: Frequent use of electronic devices, whose blue light may irritate the eyes, can potentially cause lens degeneration and result in flashing lights in one side of the eyes. Reducing the time spent on electronic devices and performing more eye exercises to promote eye blood circulation can help.

3. Vitreous Traction on the Retina: Detachment of the vitreous body at the fundus of the eye and traction on the retina can cause a sensation of lightning, which, in severe cases, may lead to retinal cracks. It is recommended to undergo ophthalmic examinations, including dilation of the pupils to examine the fundus, B-scan ultrasonography of the eyes, and fundus photography.

4. Optic Nerve Diseases: Optic nerve damage and inflammation can cause similar symptoms, requiring visual acuity tests, electrophysiological tests, and other examinations.
