Polarized lenses block up to 50% of the light to pass through the lens and filter out the reflection of light. They increase your visual comfort by reducing glare from smooth surfaces such as roads, water, snow, and glass. Polarized sunglasses are available in brown, green-grey, and grey tints. You can transform any pair of frames into sunglasses with 100% UVA and UVB protection.
Your frame measurements (mm)
Frame size is determined by the three key measurements found inside the frame arm: lens width (from 31-60mm), bridge width (from 12-31mm), and arm length (from 115-155mm).
Your lens height (mm)
Lens height is essential for multifocal prescriptions, such as Progressives, which require a minimum measurement of 28-30mm. They are also recommended for Rx sunglasses.
