MYI Occlusion Eye Patches were designed for the treatment of amblyopia (lazy eye), strabismus, and other eye related issues. The MYI eye patch is designed to be PEEK-FREE, there are no tiny holes in the non-woven material to fixate through – if a child can see through the holes of the patch, they are not patched. The thin black occlusion layer provides for total occlusion, but is thin so it is comfortable to the eyelashes. To allow kid to be kids, MYI eye patches are made using an "aggressive" adhesive so it will stick when other patches don't – they do not come off in water, from sweat, humidity or tears. This medical/surgical grade adhesive is HYPO-ALLERGENIC and LATEX FREE. MYI Eye Regular Size patches may be used for children of about 3 years to adult. MYI Occlusion Eye Patches are proudly made in the USA.
