A snake about to shed its skin? One you can be less afraid of?

　　Here is a picture of a garter snake with blue eyes. The eyes are only blue in the photo because the loose skin over its eyes (and rest of body) is about to be shed. So most snakes at some point in their lives will have blue eyes. The eyes revert to yellow, brown or other usual colour once the skin is shed.

　　Snakes about to shed their skins are normally slower moving and less responsive to their external environment, too much energy devoted to growing the new skin, I suppose. They also can't see as well as usual -- but their sense of smell is fine. And smell is how they locate their prey, usual.

　　Garter snakes are very common in North America, and virtually harmless.

　　Some very white or nearly albino snakes also end up with blue eyes. See example here. Some varieties of corn snake (another harmless North American variety) are being bred to be pure white. Some of these specimens have red eyes (true albinos), others have blue eyes.
