The hydrooptix Mega 4.5 DD mask. The only mask to incorporate a dome shape lens which increases your overall width of vision 5x compared to a flat mask.
So how does it work? The dome shape of the mask, when in water creates a prescription the equivelent to -4.5 dioptre (a short sighted prescriptoin of -4.50 ) - You can wear this mask even if you are not short sighted by wearing contact lenses with it that has the opposite power to neutralise the effect of the mask. The biggest benefit of this mask is the width of vision that you get compared to a flat mask. If you think this mask is for you but are unsure whether it would work please email or call us with your prescription
