Lens treated with a scratch-resistant coating have a much harder surface and are far more resistant to scratches from daily use.
Scratch resistant coatings is especially beneficial for children’s vision-wear to increase durability and wear.
Keep in mind, even the best scratch-resistant coating can’t completely protect your lenses from wear and tear, but will greatly reduce most scratches from daily use and cleaning.
Anti-reflective coatings reduce the reflections on your optical lenses and reduces the amount of light going in to your eyes, helping with light sensitive eyes. In addition, anti-reflective coatings reduce glare and make your eyes more visible through the lenses. This is particularly useful when you are wearing glasses in photos.
UV-blocking treatments are like a sunscreen for your vision. The UV coating reduces the amount of harmful UV rays transmitting through the lens and aids in preventing protecting the eyes from sun damage and issues such as cataracts and pterygiums.
Polarized lenses have a special coating that blocks out glare and can make color and detail seem sharper than non-polarized sunglasses. With increase vibrancy and contrast, polarized lenses also reduce eye-strain and are especially optimal for driving in bright sunlight.
Digital devices such as computer and smartphone screens emit blue light known as High Energy Visible (HEV).
This blue light is part of the visible spectrum and has been shown to cause eye strain, headaches, and disruption to the body’s natural melatonin production — the hormone that aids with restful sleep. This HEV light can be problematic for those who work at the computer for long periods of time.
The Blue Light Blocker lens coating filters out about 40% of the blue light emitted by digital devices thus reducing eye strain, headaches and helps improve sleep patterns.
Now that we use digital devices as part our daily lives, it is important to protect our eyes from HEV light.
