What are these gray marks in the whites of my eyes?

[KarateF]

So, all my life, I've had these "birthmarks" in my eyes, which are these gray colored blotches floating around all in the whites of my eyes. They haven't grown, or moved, and there's just as much in my right eye as there is in my left. I've noticed no one else that I've met even has anything close to what I do. I know my mom has one single dark dot in one of her eyes,and that's it. Just curious, since I can't for the life of me figure out what they are called, and I can't find out anything online. They don't hurt or anything. My vision is perfectly okay, I suppose. My right eye is 20/30, left is 20/20, so nothing really. Here are some pictures however that I took.

These are some of my right eye:

And one of my left eye:

Let me know if you know, or if you know some sort of website that does. Thanks.

I have these gray marks in my eyes my mother once had them as well. Hers have disappeared , but mine are still visible. The marks never hurt or gets irritated ,ive had them for years. I would just like to know what are they but they look nothing like the images i see on the internet.

YEs I can see it.  Well the sclera is thinning than normal that can make it more sensitive to sun, wind, dust, drying, pollen, etc. Since it goes away overnight it should not be a problem.

Thank you, for clearing that up actually. Though I did forget to mention (And good timing too, I suppose) is sometimes my left eye gets kind of irritated around one of the darker spots. Right now, its bloodshot and kind of sore feeling, but only on that certain spot... Here's a picture of it this time around.

You can see it on the right in that picture compared to the other one.

It usually goes away over night. But its happened several times before that I can remember, and only in my left eye on that same spot. Is it anything to be really concerned about?

Thos look like thin areas in the white of your eye (sclera) that allow the blue of the underlying layer (choroid) to show through. Since you've had them all your life its not something to worry about. More common in fair skin, blonde eyed people.
