If you’re dissatisfied with a limited underwater view when diving, then you might be interested to learn about Hydrooptix’ Mega-4.5d mask. After years of engineering, Jon Kranhouse – with the help of Hollywood computer gurus, who helped correct the once-fuzzy Hubble Space Telescope – has developed a mask that reportedly provides “a view almost five times wider than the view available through conventional flat masks, and the vision is completely distortion free.” Sounds great! But there is one small drawback…

Makes sense -- a flat view is inherently limited, and with the crazy optical properties of water, flat side vision doesn't work -- and standard curved technology would be entirely too distorted.

Because the “concave shape of water” creates an optical phenomenon, you must be nearsighted to use the mask. Many naturally nearsighted divers can use the Mega-4.5d with just their naked eyes. Apparently the view is so astonishing, however, that many divers with 20/20 vision have purchased contact lenses just to use the mask. Voluntarily becoming temporarily nearsighted, the divers claim that wearing contacts is worth the hassle, because of the vast improvement in vision. I wouldn’t’ve believed it if I hadn’t looked at the testimonials. The Mega-4.5d ships for $200; contact lenses not included.

Woo! I use a prescription mask now, that my mom gave me after her Lasik surgery. They work ok, but I worry about the difference in prescription. In this case... I finally have a vision advantage.

(Until I go through surgery, of course. It would be funny to start being a contact user AFTER losing the need for glasses).
