Hello
I don't know if this is it, so a trip to your eye doctor will test to find the cause, but this is what I found in doing research on your answer:
The earliest symptom of macular degeneration usually is persistently blurred vision. As more cells of the macula are destroyed, objects become distorted (for instance, straight lines become crooked). Eventually, a small blind spot in the central visual field can develop and grow in size. This can progress to the point of “doughnut” vision, where people’s faces are unrecognizable when looking directly at them, yet peripheral vision remains unaffected.
