finally a good day for a sunrise

This morning the sky was very clear and the sun was very bright. I watched the sun rise for 15 minutes. I tried to focus both eyes on it but I could not get my right eye to cooperate.

Here is a picture of what I look like with my eyes not working together.



I am watching the sun as it rises over the land of the rising sun. Or am I? Well at least half of me is.

Just before the sun came up, there was a colored tint on the horizon. Looking at that color with one eye at a time, I notice the right eye sees it much darker than the left eye. The same thing can be said when looking at the sun.

I remembered the technical term for the eye doctors. The ones I have seen in the past are optometrists and the one I should go see is an ophthalmologist.

If I may, there is a question that's been on my mind for a long time, but which I could never ask anyone. Since you're directly address the issue of your eyes, I thought I'd ask --

If the eyes look in different directions, somehow the brain must compensate and have a way to concentrate on only one of the two images. In other words, how well can you tune out the secondary image? Are there instances where the larger field of vision it creates is advantageous?

As for both eyes seeing differently, I think it's pretty much the norm. I've heard that the iris colour also influences the colours we see and our irises are never exactly the same colour.

Hi Alexandre.
I can actually switch which eye is looking forward and that makes the other one turn outward. I can do that by focusing the eye I want to see with.

The secondary image as you call it, is like peripheral vision. You can notice something come into that area even though you're not looking directly at it. So as far as tuning out the picture, it's the same as not paying attention to what's in your peripheral vision. The only advantage is the wider field of peripheral vision on the one side, although not very useful.

I'd been wondering that for a long time. Thank you for taking the time to answer.
