If you are seeing flashes of light in your peripheral vision, it is highly recommended to see your optometrist right away. Do not panic, as in most cases, this is not indicative of a serious eye condition. Flashes do not last for any set period of time, and they may continue on and off for weeks or months.
What are the possible causes?
- When there is a sudden change in light, from dark to very bright
- Severe headaches or migraines
- Your glasses or contact lens prescription needs to modified
- If you are seeing halos of light, that could be a sign of cataracts
- Sudden and frequent flashes may be a sign of retinal detachment, a serious condition which should be diagnosed and treated right away
How are flashing lights or flashes treated?
- In cases of entering into very bright light, the right pair of uv-protection sunglasses will solve the problem
- A new prescription for your eyeglasses
- In rare cases, ocular surgery will be required to address the problem
