Review title is These are a NO. [SEP] If you need an eye patch for medical reasons, skip these. They have no structure, are flat and press into your eye. The strap... ugh. All the choices of colors was why I bought these but the way the strap is sewn to the patch makes them almost unbearable to wear. Plus, If you need these for your left eye, you're gonna have an o-ring in the middle of your forehead. Plus, they came all wrinkled. Fast shipping... for a big bag of NOPE.
