Product Description

We answered the need early-on for prescription mask lenses. A pioneer innovator in supplying prescription diving mask lenses, Seavenger.com offers a range of interchangeable lenses in clear, tinted and optical prescription choices including bi-focal diopters. These high-end lenses from manufacturers such as IST and Tilos can be fitted to a variety of different mask styles and facial profiles, including children. Clear lenses are made from super-transparent glass, and offer stunning panoramic underwater viewing, as well as gauge reader bifocal diopters available on select masks. Prescription lenses range from -1.0 to -8.0 for divers who are near-sighted, and +1.0 and 4.0 for those who are far-sighted. A selection of tinted lenses offer sharp clear vision and drastically reduced glare both on the surface, and underwater. You can order prescription optical lenses for most l twin-lens masks and select goggles.


Seavenger presents for the first time: Gauge Reader Bifocals! Because of tremendous demand, we now offer bifocals in an extremely high quality mask, the Hawk Eyes from Tilos. The larger, two-window styling of this mask is designed to increase downward vision. It’s combined field of vision was among the best as tested by Scuba Diving Magazine. Their testers found the Hawk Eyes to be comfortable with a soft, pliable silicone skirt. The Hawk Eyes is easy to clear and equalize, and Scuba Diving testers really liked the E-Band strap – a patented device that sets the adjustment features of the strap squarely in the back of your head, where it rests on a comfortable, hard-plastic band. Hawk Eyes – for those of you who have been looking for a great all-purpose, all-face mask that’s available in bifocals – the search is over. Available in multi-hued sporty Red, Black, Clear Blue, Pink, Blue and Yellow.


  •     Large two-window design offers excellent wider down view
  •     Rubber coating on corners of outer frame absorb impact
  •     Indented nose pocket permits easier equalization process
  •     Quick release buckles located on skirt for compact storage
  •     Crystal silicone skirt and strap
  •     Packaged in heavy duty plastic box
  •     Corrective lenses available in bifocal + diopters (Only bottom of lenses)




Question What mask do you suggest? I wear progressive lenses (bifocal). Prescription is below

OD SPH:2.75, CYL:-0.25, Axis:80 ADD 2.0
OS SPH:3.00, CYL:-0.25, Axis:90 ADD:2.25


Answer The TI--M480 is the only bifocal mask we sell. This products got very good reputation. If you want the mask with far sights RX lens, we recommend you to buy M55. http://seavenger.com/hawk-eyes-scuba-diving-mask-with-bifocal-compatible-gauge-reader-clear-blue-p-1431.html
M55 also provide more options for the lens. Please kindly let us know if you have further questions.

Question My doctor gave me this prescription what do I need?
o.d.-6.00 -1.00 x 090 +2.50
o.s.-9.75 -1.00 x 123 +2.50

I do not have the PD or near PD

Answer Right Eye: -6.50

Your reading is over what we can offer. The number showing here is the best we can offer you.
The link FYI:

Question I need a small adult snorkel mask with the following bifocal prescription:
o.d. spherical + 6 cylindrical -4 axis 170
o.s + 5.5 -3.75 002
o.d +2.75
o.s. +2.75

What brand do you suggest and what would be the cost?
And, what is a "bifocal compatible gauge reader"?

Answer Unfortunately, we cannot fulfill your needs for a bifocal dive mask with readers beneath, and far-sighted prescription lenses above in one mask. We do have this mask for smaller facial profiles, which can accommodate your prescription with +4 for OD and OS. The cost of this mask is $74.95
And for the "bifocal compatible gauge reader" which is a mask with the lower part as a reader and the upper part clear, non-prescription, it is $65 including +2.75 lenses.

Question my perscription is
right +.25 -100 x 80 add + 2.5

left +2.75 -.5 x 100 2Bin 2Bup add +2.75
I normall wear tri focals for normal vision
and bifocal intmedicte and readers for bench work

what is available and what would you suggest

Answer We have two options for prescription lenses. The bifocals are the Hawk Eyes you have referenced (in several models), and these are available in +1.75, +2.25 and +2.75. We then have a wide variety of prescription masks, but these are only available in the prescriptions with the full lens, no trifocals, multifocals or progressives.

Question this is very confusing.
my prescription reads:
Right +075 -.50 93 +200
Left +100 -.25 95 +200
Please advise what I should designate in my order

also my wifes prescription reads:
Right -5.75 -.75 178 +2.00
Left -6.75 0.50 170 +2.00

Appreciate your help!

Question Hi,
I just received my dive mask and it seems to be perfect. Just one question, On my non-prescription dive masks I rubbed them with toothpaste to get the coating off. Is there a coating on these and do I have to lightly rub them like my other dive masks to remove any coating?
Ed O'Mara

Answer Yes, there is a coating that needs to be lightly rubbed like other dive masks.

Question My doctor gave me this prescription what do I need?
o.d.+275--050 104 +200
o.s.+225--050 140 +200

O.D. --- +2.75---050 104 +150
O.S. --- +2.25---050 104 +150
I told him this was for a dive mask and he was a commercial diver so I believe he knew what he was talking about but I don't. What do you suggest?

Answer We recommend +3.0 and +2.5

Question Does bifocal + diopter at +2.75 mean that the lense has a 2.75x magnification area on the bottom of area of the lense while the top is normal non magnified safety glass? Thanks, Mike
Answer Yes, that is how the lens is set up.

Question So i have my eyeglass prescription- how do i know what information to provide?
Answer Use either of these equations to determine the best mask diopter for your eyes.

(a) Sphere + 1/2 Cylinder = Mask Diopter

(b) Myopia + 1/2 Astigmatism = Mask Diopter
