What is the difference between single-vision and progressive lenses?
Single-vision lenses offer one correction throughout the entire lens (usually for distance or reading). Progressive lenses offer multiple focal corrections in one lens, providing a seamless transition from distance correction on top to reading correction on bottom. This means you can see your whole field of vision without switching between multiple pairs of glasses.

What are polarized lenses?
All sunglasses are designed to reduce brightness, but glare from the sun can still cause eye strain, squinting or even temporary blindness. Polarized lenses provide 100% protection from glare and UV rays.
How do polarized lenses work?
Visible light waves from the sun travel in all directions. When sunlight reflects off a horizontal surface, like a road or water, it often becomes concentrated horizontally. This is known as glare. Vertical light is useful to the human eye, but glare masks useful light, making it difficult and uncomfortable to see. Polarized lenses block […]
