IST is a watersports industry pioneer in prescription lens masks, and we’ve brought that expertise to bear in the IST G40 Modular Prescription Goggle System with Replaceable Parts. This system offers a convenient, affordable way to get a completely custom set of prescription swim goggles you can update if your prescription changes.
It all starts with the hypoallergenic, injection molded silicone comfort split strap, which comes packaged with three impact-resistant plastic nose bridges for use in assembling your goggles.
Hypoallergenic, injection molded silicone is used in construction of the eyecups to ensure a snug fit without creating excessive pressure around the eyes. Lenses are made of scratch and UV-resistant, anti-fog, shatterproof polycarbonate material for safety and durability. Strap clips are built into the sides of the lenses, and allow for easy adjustment to fit adults or kids.
Lenses are available in diopter correction from -1.0 to -10.0 decrement and +1.0 to +8.0 increment. If your prescription is different for each eye, order a complete set in the diopter correction needed for the first eye and an additional lens for the diopter correction required by the second eye. Left and right lenses are interchangeable.
If your prescription changes there’s no need to buy a whole new set of goggles: just order the replacement lens(es) you need and substitute them for the old lens(es).
The complete G40 system comes pre-assembled in a sturdy storage case.

IST G40 prescription swim goggles
This is the second pair of these swim goggles I have purchased. They work great. Had to replace my first pair from last year due to scratches and sun exposure deterioration.
They fit very well and are comfortable. Not many company's offer "+" correction goggles and these do the job for me. I have used them now for about 5 hours of swimming laps and have not have had problem with fogging.

This goggles are excellent comfortable and helps me see
Best "old school" goggle left on market
It is actually hard to find goggles similar to the original Speedo goggles for training and everyday use. Most do not allow adjustment of the nose piece and are rather small overall. The IST G40 goggles can be ordered "plano", i.e., without any prescription. I have multiple sets of plano and prescription goggles for various situations. Also IST is almost the only vendor selling generic prescription inserts for goggles with the high diopters like -9 and -10. . Recommended.
