No I wouldn't consider these as viable everyday wear, but given how badly nearsighted I am, they still give me much better focus than my natural vision.
I got 2 pairs of these delivered today for only $7.16 total ๐
They help improve blurry vision to an extent, without needing a prescription. They're definitely not any substitute for prescription glasses for everyday wear, but for $7.16 for 2 pairs of them, they're a fine emergency backup.
Though they are a little odd to look through, but not too bad really. Still, with all that said, I definitely would not recommend driving a vehicle with them on.
