I purchased this eye patch to see if it would help me with one eye becoming too dry at night from my CPAP mask leaking. The patch feels comfortable and is rigid enough to keep away from my eye lashes. It also provided a good yet soft seal around my eye. The main drawback was the strap and metal slides. I extended the strap as far as it would go and the metal slides ended up just above and to the left of my left eye. Initially there wasn't any discomfort but by the morning, I was in alot of pain where the metal slide was pressing on my skin. The strap also felt tight even though I extended it to the limit. I wear a size 7 1/4 hat so my head is average.
For temporary use, this patch will probably work but for any extended wear, it needs some more development on the strap.
