Very good - they stick well and I can see great!
These are great. I use them inside my lamp working didymium glasses. It was painful to wear my sight glasses under the lamp working glasses, prescription didymiums are horribly expensive and so are the fit-over glasses, so I gave these a try. I have had no problems with them falling off, as other buyers have. For my personal use, they would have been nice slightly bigger, but they do the job very well. Very pleased with them for the price.

Excellent product,, a bit difficult to fit.
They work perfectly. The only issue I had with them was that, when fixing them to my glasses, it was difficult to banish a bubble under one of them. I managed it after several tries.

Incredible product
Turns your glass into bifocals, no hassle. They stick on with a drop of water and form an impressive seal. I can actually see my phone screen now.

Garbage, not worth the money
These might be fine if the existing host lens is perfectly flat, but even with a slight curve these will fail to stick tight.! Followed all the instructions to the letter, sought out additional tips online, and still these lenses continued to come loose. Absolute waste of money.

Dive Mask works.
I stuck mine on outside of Dive Mask with UV epoxy resin (gorrilla brand) and it works perfectly, tried n tested after ten days diving. Show no sign of budging. I'm normally+150 for reading but got +250 to account for the future. I'm really impressed.

Safety critical with cycling goggles that they don't obscure road vision.
I like to be able to glance at my Garmin while riding and as an ageing cyclist need reading glasses. My lenses needed trimming slightly to avoid interfering with road vision; provided you cut them cleanly they still adhere perfectly. Rest of cycling group interested.

Easy to fit and worked well underwater
Worked well in my diving mask, albeit they could have been a little larger. Very easy to fit and a very good price compared to buying a prescription mask.

Reduced size
The size of the lenses has been drastically reduced. Why. I liked them when they were the original size, slightly bigger. They are too small now

Souple et efficace
Exactement ce que je cherchais pour mettre dans mon masque de plongée. Solution simple et peu onéreuse et efficace. Collée avec de la glue spéciale verre, ça fait le taf !

Como unas bifocales pero a bajo precio
Yo desde luego estoy encantada. Al principio las coloqué demasiado abajo por lo que no era cómodo, ahora las he despegado y las he vuelto a colocar y me resulta muy cómodo además de económico. Las he puesto en gafas de sol y en caras sin graduación y fenomenal ambas. Yo lo recomiendo.

Für Taucherbrille geeignet
Es funktioniert tatsächlich auch in der Taucherbrille. Zuhause fixiert haben die Linsen mehrere Tauchgänge gehalten, mit Antibeschlagmittel und Ausblasen.... Dann habe ich die Linsen nochmal abgelöst und etwas höher gesetzt. Eine Linse war über Nacht mit einer Luftblase, diese habe ich vorm nächsten Tauchen herausgenommen. Die zweite Linse habe ich bei dem Tauchgang verloren. Für die verbliebene Linse nahm ich mir jetzt mehr Zeit mit Reinigung der Brille, dem Fixieren mit Süßwasser und Trocknen. Die zweite hat dann weitere 14 Tage Schnorcheln und Tauchen problemlos gehalten. Ergo es funktioniert bei entsprechendem Händling.
