That much weaker refraction is what enables us to see where it's pointing. This is how light works - you can learn more about this here. So the screen of an e-ink reader catches the brunt of the light,and we only see the very weak refraction produced by the screen not absorbing all of the light - thus, eye fatigue is greatly reduced because we're seeing a "secondary" light ray and we're seeing it at a "lesser" angle. |
I think the word you want is reflected - light hitting something and bouncing off as opposed to refracted - light passing through something and being bent (usually in another direction unless the same density as air)...
