Hydrotac Lenses for Presbyopia/Additional Removable Lenses/Lenses For Sunglasses Cycling Fishing Diving Mask, Clear, +2.50

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.

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.

These worked well on two pairs of sun glasses whilst on a European cycling holiday. First on my regular Ray Bans and then easily removed and put onto my cycling glasses. They took a little getting used to whilst cycling but over all were very useful.

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.

Idea good, The product worked well, but unfortunately one came off and fell into a lake.

Great product.... due to cancer my eyesight deteriorated drastically, meaning needed specs at all time.... as such my Ray Bans and such looked like no longer of any major uses.... Nope... popped inside my Ray'bs now got great sunglasses when driving, as bifocals... will get more to fit inside my others too

A great buy. Solved the problem of being unable to see GPS while riding my bike. Cut top and bottom off lenses to keep them out of main field of vision and fixed easiy to to fairly large lense on Oakley photochromatic glasses. Works a treat and can now also see clearly to take pics on phone without having to carry reading glasses. Much cheaper than prescription glasses option.

Applied to a scuba mask, following all directions. One lens came off on the first dive, the other on the second dive. Absolutely useless pieces of overpriced plastic!

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 !

Wie beschrieben mit einem Tropfen, meint ganz wenig Wasser aufgebracht und fest angedrückt (!) halten die Linsen in der Taucherbrille super. Dies gilt auch wenn die Brille permanent naß ist und auch nach mehreren Tauchgängen. Jetzt kommt der Wermutstropfen. Da die Linsen aus Kunststoff und damit hydrophob (wasserabweisend) sind, neigen sie in der Taucherbrille zum Beschlagen. Trotz den guten optischen Qualität habe ich sie deswegen wieder entfernt. :-((

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.

Trovata geniale che risolve molti problemi e abbinati ad un occhiale da sole sono utilissime

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
