That sounds like an astigmatism to me, which basically just means your lens is a little misshapen. I have a pretty bad astigmatism in one eye and have double vision in that eye without glasses, especially so from lit things like screens.

Go to an eye doctor, they can diagnose. It's likely just something as simple as an astigmatism and some glasses should help you with that.
