| I have no background in eyes but I have on rats. I can't affirm that the differences would make that study invalid. I can however tell you a few facts about rat eyes. - Their eyes are sensitive to ultraviolet. - They have a dichromatic vision, two sets of cones instead of three. (some short wavelengths of ultraviolet/blue and a lot of greens) - They cannot reshape their lenses. - They have a lot more photo-receptors on their retina than us. - They are something between farsighted and nearsighted. - Poor binocular vision but big field of view. Albino rats have more differences but I doubt they would have used any of those in a study on eyes. Rats do get the same kind of eyes disease humans do (cataracts, etc.) however their sensitivity to light is really different. I don't think that it is ideal to use such different eyes to test LEDs sensitivity. |
