Hydrotac Stick-On Bifocal Lenses (+2.00)

I use the lenses with cycling sunglasses for both on-road and off-road biking. I have used them in wet and dry conditions and they have worked flawlessly for me. I’m now able to read my cycle computer on the go, read and reply to phone messages and most importantly sort out cash for a brew and cake and the cafe without having to take my specs with me. I have now bought two packs of these lenses and I am very happy indeed. I followed the instructions from the company website and the lenses haven’t moved since I put them in many weeks ago, and I would not hesitate recommending them.

I bought three to get better use of my vintage Ray-Bans this summer. +2.0 needed.The product is excellent. Simply follow the instructions and your away with a high quality lens. Clean the glasses, apply a smalll drop of water to the sunglasses, put the Hydrotac lens in place and gently press with a soft cloth. The water disperses and the lenses stick. They’re still stuck, yet easy to remove or reposition. Just sticking with water molecular bonding. Amazing physics.The quality of the optics is very good. I have varilux X-Series lenses in my prescription glasses and the quality of these lenses help me read very clearly and sharply with my sun glasses. Brilliant product.

If you are considering buying these you should be aware that there is a "NO RETURN" policy, so if you have the same problem I had you are stuck with a 17 quid loss.Great while they stay attached, the problem is they dont.I got these to modify a pair of glasses for use on my motorcycle. Even though they were used under a visor they keep falling off, luckily into the chin protector.I shall go back to the old trick of using contact lenses stuck to the glasses. I have tried glasses with different curvature profiles but the problem is the same.

Not optically perfect and overpriced but does the job. The alternative is getting bi focals, so I will have to see how these last.

These don't still very well especially if your glasses/lens is even slightly curved.If you placed them in your glasses and sat reading a book without touching your glasses then they kind of work.Don't expect to be able to put your glasses in your pocket or push them back on top of your head or put your glasses in your pocket. The lenses just won't stay stuck.Also don't expect to be able to wipe your glasses unless you wipe 'very' carefully.I decided to buy a bifocal sun glasses instead - actually cheaper than these 'stick-on/fall-off' lenses.Bear in mind there's a "No return" policy on these lenses.

These are not cheap but easy to apply. I have fixed them to my sunglasses and they don't show from the front. Ideal for reading menus in the sun!

These are perfect for use with my cycling sunglasses. Allows me to actually see clearly my Garmin whilst riding and also enables me to answer my phone without having to put on my reading glasses! Great product, little expensive but well worth it.

Lens is big and can induce a feeling of sea-sickness. This is NOT a replacement for proper glasses, bifocals, varifocals or even two pairs. Despite installing EXACTLY as per instructions, one lens fell off and was lost. Having only one lens at a critical point could be hazardous.

Ero non scettico ma di più!! Le ho acquistare per utilizzarle sulla mia maschera da sub, è mi dicevo “ci provo, ma tanto alla prima immersione le perdo” ed invece dopo circa 40 immersioni sono ancora lì, attaccate al vetro con solo una goccia d’acqua, sembra incredibile, ma è così. Ho amici che hanno speso centinaia di Euro per maschere graduate ed io ho risolto con poco più di 30€. COMPRATELE!!!

J'ai lu les avis avant d'acheter cet article et j'avais peur que comme indiqué par certains au "premier vidage de masque elles disparaissent" et pas du tout.J'ai nettoyé l'intérieur de mon masque avec une brosse a dent et du produit vaisselle + eau tiède, pour bien le dégraisser.Je les ai appliquées comme indiqué dans la notice et laissé séché (installées le jeudi et première plongée le lundi). Elles n'ont pas bougé de la semaine (9 plongées dont 3 au delà de 50 mètres).Ma vision s'est trouvé nettement amélioré sans déformations pour la lecture de l'ordinateur.J'ai démonté celle de droite car je me suis aperçu que je ne m'en servait pas et je l'ai rangé pour en avoir une d'avance.Très satisfait de cet achat et pour un prix plus que raisonable.

The first time I bought these, they wouldn't adhere to the lenses and was obvious they were used and damaged from shipping. Also, No returns are available. I took a risky chance on buying a second set because I REALLY wanted these to work for my sunglasses. The next set worked like a charm. I put them on one set of riding glasses and then removed them a week later, under water, and put them on another set and the set up well. I'm pleased and will buy another set. They are easy to cut with an exacto knife and custom fit. Watch the youtube videos out there for help before trying to install them.

Buen producto

Los he puesto en unas gafas de sol que utilizo para salir con la bici y van muy bien. Me han venido muy bien porque apenas veía el GPS.Hay que calcular bien dónde deben ir e intentar que queden por debajo del el centro del ojo para que no molesten a la vista de lejos .
