For Duo Shields with clear lenses,

Description (by Rebecca)

Classic style of inexpensive goggle used after surgery. You know those hard plastic tape-on shields? This goggle is basically those shields with a white foam lining for comfort and moisture seal and some elastic connecting the two shields as well as a thin elastic strap to hold it on.

Pros - inexpensive, very lightweight and reasonably comfortable.

Cons - very thin strap (so it may not stay in place, depending how you sleep); no actual seal because both types (see below) are vented. Some people cover the holds with tape.

There are two styles of Duo Shield:

'Moisture retention'. This is NOT a completely sealed moisture chamber; each eye cup has vents near the nose bridge; but they will hold more moisture than the other one.
Vented - This is the classic post surgical goggle with several air holes in the plastic eye cup - this is NOT a moisture chamber, but rather a protective shield to make sure nothing touches your eyes. It's a more comfortable alternative to tape-on shields.

As with everything you consider wearing over your eyes at night, make sure you check with your doctor to confirm it's appropriate for your situation.
