DGX Rio Mask with Vision Correcting Lenses
The DGX Rio may be fitted with -1.00 to -8.00 diopter vision correcting lenses, for divers who are nearsighted. Your mask and lens will be assembled and will Ship Today. The DGX Rio offers a slightly larger faceplate and lens area, with the tradeoff that the mask is not quite as low volume. The DGX Rio mask with vision correcting lenses fits most narrow-to-standard faces, but is not recommended if you have facial hair or prominent laugh lines.
To order, consult your eyeglass or contact prescription for the proper amount of spherical power correction, and then select the mask lenses. When reading your prescription, "OS" means your left eye, and "OD" means your right eye. Strength for the lenses ranges from -1.0 to -8.0 diopter in half diopters. If you have a quarter diopter prescription, then increase to the next higher diopter. For example, if the Rx is -1.75, then increase to -2.0 diopter. If one eye needs no correction, then order a "Plano" lens for that side. If your Rx also has a cylinder power value with an axis value, you have an astigmatism and these lenses do not correct for astigmatism.

on 22 October, 2018I haven't had a chance to dive with these yet and need to shave before I can really comment on the fit but so far so good! Mask looks to be high quality, as do the lenses, and as a bonus I hadn't anticipated the non corrected lenses were included as well which means if I ever go back to contacts I could still use this mask!
Order shipped amazingly quickly too, happy all around.

Ordering Vision Correcting Lenses for Dive Masks
To order, consult your eyeglass or contact prescription for the proper amount of spherical power correction, and then select the mask lenses. When reading your prescription, "OS" means your left eye, and "OD" means your right eye. The power of the correction amount is referred to as the "sphere" value expressed in diopters, and we offer vision correction lenses pre-manufactured in a range of diopter values. If your Rx also has "cylinder" and "axis" values, you have an astigmatism and our lenses do not correct for astigmatism.
The sphere strength for the lenses that correct nearsightedness, i.e. for divers that require distance vision correction, are negative values ranging from -1.0 to -8.0 diopter in half diopters. If you have a quarter diopter prescription, then increase to the next higher diopter. For example, if the Rx is -1.75, then increase to -2.0 diopter. If one eye needs no correction, then order a "Plano" lens for that side. Note, if your Rx sphere value is "+" then you are farsighted, also known as presbyopia, and unfortunately we only offer farsighted correction in the form of bifocal lenses.
If you need vision correction in order to read a book or view a phone screen, then you will benefit from using one of our bifocal "gauge reader" masks. A inset at the bottom of each lens adds magnification to see close-up objects, such as gauges, with clarity and yet still provide a means for clear sight at distances. A magnification of +2 diopters works for most people but some masks can be configured with bifocal lenses of +1, +2 or +3 diopters. Conventional wisdom suggests you can estimate + diopter reading value by age: 40 years old -start with a +1, then 50 years old use +2, and 60 years old select +3. However, making your selection based on your personal vision prescription is best.
Finally, all the standard vision correcting masks offered by Dive Gear Express have the correction ground into the lenses themselves. The correction is not aftermarket 'stick on', each of the lenses are ground just like you would expect on a pair of eyeglasses. Please note that the bifocal gauge reader versions are a two layer lens bonded at the factory prior to grinding.
