Stick-On Bifocals, +200

Yo pongo 5 estrellas pues aunque es latoso quitar y ponerlos cuando se deben limpiar las gafas es una gran alternativa de usar mis lentes de sol favoritos sin mandarlos graduar, me gustaron mucho. Además no lo haces diario ni todo el tiempo.

These are fantastic. I can finally wear cool sunnies again. Just make sure you let it take hold properly before using or getting them accidentally wet. Try to avoid water. Really good value for money especially when compared to the US Amazon site, where many items are jacked up to a ridiculous price as soon as they are put on the Australian Amazon site, these are a pretty fair equivalent. Thanks to the seller for keeping costs honest.

Really good just the job

Mit den Linsen kann man jede Sonnenbrille oder Fahrradbrille für wenig Geld in eine Lesebrille verwandeln.

I have, or have bought, about 8 sets of these over the years that I use for non-prescription sunglasses in my car and on sunglasses I use for cycling. I have been using these for at least 5 years. I have sets that have been on glasses, in the sun, for at least 3 years and they have never fallen off or otherwise become unusable. I replace them only because when I (rarely) take them off the glasses to clean the glasses (after thousands of miles cycling road grime) I notice that they yellow over time in the sun. Like ski goggles, I don't ever notice the yellow tint, but every now and again I like to start fresh. I always have at least one spare set of new inserts in case I destroy a set of glasses or buy an additional pair. I keep these in my Amazon cart and usually pick up a pair when there is a temporary price drop. I only wear reading glasses, but at the 2 to 2.5+ level, and can't read my car gauges or my cycling computer without readers or these inserts. These work very well for me for driving and cycling. Hopefully, my eyes will stay about the same for the foreseeable future, and if they do, I will continue to apply these to all my sunglasses. If they don't? Well, I'll cross that bridge when it happens.
