Review (2/5): Not just cotton and silk - contains polyester
I won't say the product is necessarily bad, but I certainly do not like it and am not pleased with the disparity between the description and the actual product.
While the amazon page says these eye-covers are made of cotton and silk, the product packaging and tags both indicate the product is cotton, silk, AND polyester. I would not have bought these had I known this as my wife reacts to polyester. This just leaves me with another useless set of eye covers that my wife can't use.
Also, I personally find these uncomfortable. The silk is nothing like my nice soft silk shirts. It is still a shiny and smooth fabric, yet also an uncomfortably rough (I'm not sure how better to describe it -- it's like running your skin over tiny closely spaced wires), fabric that is very hot to wear on your face. Furthermore, I found that I got a headache both times I tried wearing these.
My wife has previously made some passable eye-covers out of cotton socks that we both can wear -- and I find significantly more comfortable. She's suggested that maybe she can try taking these apart and using the straps and cotton parts and making better cotton-sock eye-covers. I'm skeptical and am considering returning these. I'm certainly not happy.
If you like the really slick-abrasive feeling fabrics like cheap silks or cheap satins, and if you don't have any issue with the polyester in these, I can't really see a problem with them. They could probably benefit from being a bit larger, but they're 'pillowy'-enough (for lack of a better word) to block out most of the light and fill in the gaps around the edges. Mystery as to why they give me a headache, but they've enough good reviews that it can't be common.
I'm giving them 2 stars because I think the description is misleading and I don't like them, but also because I think a more moderate rating would get this lost among rating of people who are happy with the item. I always read some of the reviews and I wish I'd seen a review like this before purchasing.
