Sclera or the whites of our eyes. . . .?
This may be a silly question but is the fact that the sclera is white affect sight in any way? I asked my mom this question and she responded that although she didn't know she did remind me that the color white reflects light, so I wondered if that had anything to do with our sight? The specific questions I want answered are these:
Does the white help our sight, and if so how?
If it does affect our sight, then what would happen if our sclera was black instead? Would we see things differently?
Thank you for taking the time to read and answer my questions.

Having white scleras is probably just natures way of making people the most attractive to each other as possible. The eye colors wouldn't show up if the scleras were black or any other color.
Many people have expressive eyes that are very attractive to potential mates that probably wouldn't show if the sclera was dark either.
It has nothing to do with our sight, so I'll bet on Mother Nature being a very smart Cupid.

The inside of your eye is not white. It ranges from light orange to dark orange. Some animals have a tapetum on the inside of their eyes which reflects light. It helps with night vision but the reflections may decrease fine vision. I am not aware of any advantage to the outside of the eye being white.
