If I close one eye, I can still see the darkness from the shut eye. It's like the brain can't focus 100% on what the open eye sees, instead I see some of the darkness from the shut eye mixing with the image from the open eye.
It's hard to explain, English isn't my native language. And I haven't heard of anyone else experience this. I once asked an eye doctor but he never heard of it.
What should i do?
Thanks for your Question
I think you should be examined by an eye doctor and he should run a special test for you called visual field. This test will us if you really have black area in your vision or just you imagine it.
