Query: WARNING...LATEX PRODUCT!

The Coverlet Eye Occlusor patches we purchased are made of natural rubber latex and many people have latex sensitivities or an allergy (we found this to be true with our daughter). Our daughter has been patching an eye for vision therapy for 3 years and never complained about it until the itchiness occurred when she used the Coverlet patch. We've always used 3M Nexcare pediatric patches which work very well and I would highly recommend to any other little patchers out there!
