Why do I see red and blue lines?

This is a case of simple refraction of the light spectrum. When light passes through a transparent material light of different wavelengths bend at different rates. The lens bends red and blue light differently, causing this chromatic aberration. The different colors travel at different speeds through the lens material.

Red color has longer wavelength and is focused beyond the retina whereas the blue color has short wavelength and is focused in front of the retina. This leads to a slight disparity and enhances depth perception.
