For a detailed review of the construction, usefulness and comfort of this type of patch, please read my description of the Pro-Moisture Chamber.
The Pro-Eye Patch is essentially identical to the Pro-Moisture Chamber except for the material at the front. Instead of a clear plastic that you can see through, this one is opaque, with a choice of white or black.
This is a good product if you need both occlusion and a moisture chamber, for example, if you're struggling with extreme light sensitivity. It fits readily under glasses.
Does it contain latex?
There is latex in the elastic band, but not in the foam.
