I love them! Much better than the toxic plastic crap from the pharmacy that was always itching me! The washing part is a little bit annoying but you will get used to it.

Ex Output:
positive

Ex Input:
Lens are super reflective making everything blurry. They do not reduce eye strain, on the contrary, they make it worse. I wouldn't waste your money on these.

Ex Output:
negative

Ex Input:
May update IF I ever receive this item! After 2 weeks...Received a notice saying the usps claimed it was undeliverable to this address... not like I haven't received a thousand items here from Amazon and mail in general. Usps said they can't even look into it since NO tracking number was provided. Not pleased.

Ex Output:
negative
