Rating: Trident Stick-On Optical Lens for Masks Review - Scuba Gear Customer Reviews
Reviewer: Robert D.
I placed the lens on the mask 48 hours before I left for my scuba trip to the Exumas. The directions for placing the lens on the mask could have been larger and more descriptive for first time users. However, once they dried and were fixed,the lens worked perfectly. Even with defogger, after 24 dives from the Aquacat live aboard for the 5 1/2 days of diving, the lens stayed fixed and performed as advertised. Dive computer and camera information was easy to read with the 2x lens I had purchased. I am very happy with the lens and they will be part of my scuba trip equipment check off list for my next dives.

Rating: Tricky Sticky
Reviewer: Rene C.
The problem with the Trident Stick-On Optical Lens is that if you dont get it right the first time, the "sticking" power of the material decreases exponentially. Warm up the mask glass face plate under hot water (as hot as you can tolerate), then flick off the excess water (as much as you can flick off, leaving only the surface of the glass humid). Place the lens and set it in place. Don’t play around with it. Leave it to set. Leave it alone. This has worked for me. Don’t expect to get the equivalent of a prescription lens. The “stick-on” is not permanent and will eventually get loose, much sooner than later than you expect. This product should be placed in your “save a dive” Kit for your alternate mask as a substitute for your prescription lens dive mask. Don’t rely on it as the perfect substitute. But for what it does as a substitute, it does what it does.

Reviewer: Yvonne F.
I have a prescription lens for my mask but use bi-vocals normally. The stick-ons are an excellent option. They are a bit frustrating to apply but follow the directions precisely and they do attach. Once they dry, they stay on extremely well. I was worried that they would detach when water floods your mask, but was happy to find that they stay on - and have used them in both fresh water and salt water. I can now read my guages easily. Would highly recommend.

Rating: Works...Sort of
Reviewer: Campbell Canup
The over all product is what it is, plastic diopters to stick onto your mask. The process of application was a little frustrating getting the lenses in place and seated correctly. The main issue is that the bottom of the lenses are curved and the bottom of the mask is square. This leaves a small gap at the base that causes some focus issues when at depth. The lenses themselves were the correct magnification but a little larger piece that your could trim to fit your mask would be preferred. After a test dive, I opted to pay the extra cost and have a mask made.

Rating: Lenses work well and stay in place
Reviewer: Paul F.  -  View all my reviews
These lenses work well and stay in place. I wear contacts but need the lenses for close up vision (2+ diopters). No adhesive is used or is necessary. To attach the lenses I cleaned the inner surface of the mask with dilute detergent, dried the inside of the mask, then put a few drops of distilled water on the inside where I planned to position the lenses. Next, I carefully placed the lenses on the inside of the mask (being careful not to get finger prints on the side of the lenses that attach to the mask. I then positioned the lenses and then pushed out any water beneath the lenses with a microfiber cloth. I let the lenses sit for 24 hours before diving. I have gone on 20 dives so far and the lenses havent moved. I highly recommend these lenses.

I purchased a pair of Trident stick on optics at 1.50 for viewing my gauges up close. They work well. I made sure my mask surface was dry and applied them the night before my dives. Warren Dunedin FL

Reviewer: Daniel L.
The stick-on optical lens were easy to install on the face mask, sit low on the lens and you dont notice them until you need to view something up close. The price for them is very reasonable for what you get. I recommend these for an in-expensive cure to being able to read things up close. Daniel Luna

The lenses are easy to install and hold remarkably well for using no glue! They do take a dive or two to get the final adjustment right, but a good inexpensive alternative to a full fledged bioptic mask.

Questions and Answers for Trident Stick-On Optical Lens for Masks:


  • Keith:

    Are these curved? I bought some Hydrotacs but they had a slight curve and thus only partially contacted the dive mask lens. I need flat optical lenses so they adhere completely and do not distort my vision.

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Keith, this item is shaped like a half moon. It is flat on the top then curves and makes a half moon.

  • Michael:

    @Darrick, Thanks for responding so quickly but that is not my question. Why order the anti-fog coated lenses if using a commercial anti-fog solution? Again there are two options with and without anti-fog coatings. Im trying to decide which option is necessary? Thanks again!

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Michael, I would go with the anti-fog coating.

  • Kari:

    I got my Rx from optometrist. ....how do I translate all the negative (-.75, -1.0) into diopter to order? Looks like only positive numbers are offered.

    Bob  (Certified Scuba Instructor at Scuba.com):

    For the Stick On Readers the "add" number or your reading glasses number is what you want to use.

  • Paul:

    How do you specify vs normal reading glasses magnification? For instances I buy reading glasses with a magnifcation of 3, what would these be specified as?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Paul, then you would need a +3.0.

  • David:

    i dove in st. thomas earlier this year the vis. was fair but i couldnt see clearly as i wear bifocals full time. i see the lens are for seeing cloeup. i just plan on snorkeling on our next trip so reading close up is not important i need to see 5-20 feet. distant. vision i am looking for a suggestion to try inexpensively. lens etc. thank you

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello David, no those would not work for you. What I would suggest is getting this: http://www.scuba.com/scuba-gear-32/027490/TUSA-Liberator-One-Mask.html then get optical lens put in this mask to match you prescription and go that route.

  • Thomas:

    Are the Trident Lens the same size as the Dive Optics lens?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Thomas, the trident are going to be a smaller lens but you can get these in .25, and .75 optical. Where as the hard lens only come in the .0, and .5 optical.

  • James:

    Will this work with domed hydroptix masks?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello James, if the mask already has optical lens in the mask you have than no it will not work right in the mask.

  • Douglas:

    I have the Dive Optics and they never stay in place. Do these lens attach the same way or do these have an adhesive backing of some sort?

    Arthur  (Certified Scuba Instructor at Scuba.com):

    Hello, these attach similarly to oil change reminders on your car windshield.

  • Art:

    I flood my mask occasionally. Will these stay on the lens when I clear it or will they float off into the ocean?

    Arthur  (Certified Scuba Instructor at Scuba.com):

    Hello, the lenses will stay on. After you do a few floods you would want to clean and dry them out and reinstall.

  • Sandy:

    If the prescription is different for each eye, how do I order, do I use the larger maginfication?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Sandy, with the stick on lens you would need to order two different sets. Or you can get a mask that takes optical lens and have the lens in the different diopters for the different sides.

  • gustavo:

    If I use out of the water( +1.50), +1.25 I should buy?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Gustavo, you would order the same diopter you would use under water.

  • Rene:

    Good day, First, this is not a Trident product by any labelling marked on the product. Although perhaps distributed in the USA by a Trident group company (something not even ever so slightly alluded to on the packaging), it is stated to be actually manufactured under licence by a Belgian company, and distributed (as per the packaging itself) by Neoptx (Florida). Second - Try as I did, and I really did five (5) times and more, they simply do - not - stick to the mask lens. At all. I went on the manufacturer web site and religiously followed instructions, which is a visual presentation of the written instructions set out on the packaging itself. I applied them after washing hands and mask, thoroughly flushed with water, used no de-fog, applied gently and placed in correct position, massaged lightly to squeeze out air pockets, used lint-free fabric to suck out surrounding water and let dry. Once the little remaining water evaporates after patting down (as indicated in the instructions), the surface buckles and warps and simply curls off on its own. Even if I don’t pat down, once the water evaporates, it - again, curls off. I applied no heat to distort the material. It does not stick - at all - like the “oil change” reminder stickers placed on a car windshield (as mentioned in this Q&A blog). Not even close. Suggestions (aside from return & refund) ? Thank You and Kind Regards, Rene
