SportiSporti Antifog S2 Optical Goggle - Clear Lens/Black Frame - Negative 2.5

I'm nearsighted and need optical goggles in order to read the clock. I usually use Speedo goggles but I wanted to give these a try because Sporti makes good stuff. These goggles lived up to expectations, I can see the clock clearly at swim practice. This style of goggle with a fixed nose bridge is fairly difficult to adjust but once they're adjusted they really stay put. These goggles do stay put once you've got them adjusted to fit your face. I love that the listing for these goggles lets you pick exactly the diopter (optical strength) you need. When in doubt, I always round down (my glasses are sometimes -2.25, so I get the -2 optical goggles) so I can be assured that they'll be comfortable, though the clock may not be quite as in-focus as it could be.

We're going on a winter trip to the Caribbean soon and have plans to do some swimming and snorkeling, but I wear glasses, which kind of ruins the experience if everything beautiful thing under water is blurry. My lenses are -2.4, so when I saw these came in -2.5, I got excited. This review is before actually swimming with them, but when I put them on they absolutely improved my vision. Since they're not my exact prescription, it's not the most crisp, but they're a far cry better than no glasses at all! The straps don't seem the most sturdy, but I'll update this review if they break.
