Single Vision Lenses
Single Vision Lenses have a single focal point for distance vision and can be made for a wide range of prescriptions including high prism and high cylinder powers.
Single Vision lenses are made from optical crown glass for optimum optics and also available in premium lens material to make lenses thinner and more suitable for difficult scripts or for the diver wanting lenses as thin as possible. Very high scripts will need to be made in premium lens material to minimise the potential of edge lens contact with the temple area of the face.
Gauge Reader Lenses
Gauge reader lenses are made for divers needing near vision correction only and are typically used for reading your gauges.
For divers who require both Distance and Near vision, bifocal lenses are a popular option with a wide 35mm reading segment, as they feature a minimal image jump from distance to near and gives the diver optimal vision correction.
A Franklin Bifocal also offers you Distance vision but with a wider Near vision view than a normal 35mm Bifocal Lens.
