Single Vision Lens
Corrects one field of vision (near or distance) and is common amongst users under the age of 40.
High Powered Single Vision
Corrects one field of vision (near or distance) but for users with a high power (between -12.00 to +8.75) under the age of 40.
Bifocal Lens
Two powers, each that helps you see distance and near. Lower part of the lens has a clear demarcation to indicate power change.
The lens segment can be of two shapes –
D Bifocal
Kryptoc Bifocal
Progressive Lens
Offers multiple corrections in one lens – distance, computer and reading so you don’t have to switch between multiple pairs. This is common for users aged 40 and above.
Lens Index
Refractive Index decides the thickness of the lens. Especially for high powers, higher refractive indices are used to make the lens thinner.
CR-39 (1.49)
Standard thickness with highest optical clarity that works best for low-powered prescriptions (Power Range – Below 3.00 D)
1.56
Standard thickness, scratch resistant lens material that works best for low powered prescriptions (Power Range – Below 3.00 D)
Polycarbonate (1.6)
20% thinner than Standard Lens, Shatter Resistant, 100% UV Protection, Ideal for rimless frames (Power Range – Below 3.00 D to -5.00 D)
High Index (1.67)
33% thinner than Standard Lens, 100% UV Protection, Good for Rimless Frames, Suitable for high powers (Power Range above -5.00 D)
Very High Index (1.74)
45% thinner than standard lens. It is the thinnest lens material that comes with full UV Protection. Suitable for specialized high powers.

Special Add-Ons
Short Corridor
Used when the frame size is smaller than the minimum required size of a progressive design.
Transitions
Lens change tint colour based on the intensity of outdoor light.
Time to darken – Up to 10-seconds
Photochromatic
Lens changes tint colour based on the intensity of outdoor light.
Time to darken – Up to 60-seconds
Fog Free
Prevents certain opaqueness of lens due to fig formation while working in the kitchen, AC Environment, etc. or due to sudden change in moisture level.
Mirror Coating
Mirror coated lens reflects up to 40% of incoming light and therefore reduces glare. Provides a brighter field of vision.
