I've heard that if a person only has one eye, he or she will have problems with depth perception and distance judgement. For example, not being able to tell which of three items is closest, next-closest, and farthest away.
However, if I close one eye and walk through the house, or even drive my car, I have NO trouble judging depth and distance of objects. Everything looks three-dimensional, and I can still tell what's closer or farther from me.
I'd guess that if you've had binocular vision (sight in both eyes) all your life, and then suddenly lose an eye, or sight in the eye, your brain "knows" how things should be and keeps compensating for it.
If my theory is right, that would explain why people who lose sight in one eye as adults are still allowed to drive cars, but people who've been blind in one eye since birth are NOT allowed to. (I know someone like that. She's never had sight in one of her eyes, so she's never driven).
I wondered how right or wrong I am? :)

Please folks, don't just answer with "yes" or "no". It's not informative and actually I'm not even sure what you're agreeing or disagreeing with! Please explain how wrong or right I am, and the reasons behind it. Thanks! :)

Depth perception or STEREOPSIS,relies on binocular vision. The two eyes see things from slightly different angles & the brain uses this information to determine the distance from us.
Monocular cues also give us an idea of relative distance. e.g. Even with one eye, we know that an object further away appears smaller. A bird may look larger then a plane high in the sky, but we know the bird is closer. This is what we rely on whether we lose the sight from one eye or are blind in one eye from birth.
People who are blind in one eye from birth ARE able to drive if they have good visual acuity (clear vision) & a full visual field (no unnatural blind spots) in their remaining eye. Often sight defects from birth affect both eyes in some way.

O.K. I can only give you the impression that I have from your message. 1. It sounds like eye strain due to the headaches after reading. 2. The depth perception might be that one eye is stronger then the other eye. 3. Your vision has changed over the past 2 years as you feel that the problem has gotten worse. 4. When you read or use a monitor, you blink less so this can cause dry eyes, so this may cause your eyes to hurt, also it might be the eye strain. Artificial tears that are preservative free my help the dry eyes. As you vision may of changed over the past 2 years it might be an idea to get your eyes check out to see if your need glasses and also see if your eye are healthy.

True, if you cover one eye you can still tell if something is closer or further than something else, but you will have great difficulty making an estimate on the actual distances involved.
You need both eyes to accurately judge distance (or in this case, depth perception) because each eye sees the object from a slightly different perspective and the brain then combines both images into a accurate understanding of the 3D space being looked at. If you close one eye you are, essentially, only seeing half of the information available.

Your vision works in stereo and that is what gives us depth perception. If you loose sight in one eye, you will loose your depth perception. Yes, the brain will compensate for known objects and areas, but you will over time realize that there is a difference. There are depth perception tests that really show how different it is.

you are correct, depth perception is affected by vision. Both eyes must work to have depth perception.

i have lost most of my sight in my left eye from diabetic problems..I lost depth perception but after several weeks it wasnt a big deal.. at dusk and in the dark i do still have a problem.I lost the sight at age 45. i think you'r wrong abt the 1 eye person not getting a lic.

Yes you are correct. Depth perception relies on binocular vision.

"Depth perception does indeed rely on binocular vision, but it also uses many other monocular cues."
A lot of research has already been done on this and it looks like your theory is right.
