IST dive equipment has been a trusted name in scuba and watersports gear for over 35 years, and a pioneering innovator in supplying diving masks with prescription lenses. The IST Corona Twin Lens Scuba Diving Snorkeling Mask with RX Lens Option just may be the most popular mask in our vast lineup – and not only because it’s an attractively priced, prescription lens-available mask.

The Corona’s high-end lenses are made from super-transparent, tempered glass to offer stunning panoramic underwater viewing, scratch-resistance and maximum safety.

Durable polycarbonate frame holds twin windows for quick clearing of trapped water and maximum field of vision. Swivel buckles allow the diver to adjust the mask to the most desirable position for a perfect, comfortable fit.

Available black silicone skirt option blocks light from reflecting off the lens in bright water conditions, while the clear skirt option allows maximum light entry in dim water conditions.

A sturdy mask that’s ideal for use as rental equipment.
