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.
