ANTI-GLARE LENSES VS BLUE LIGHT FILTER LENSES

Now you’ve heard about the Blue Light radiation, you have heard the science behind it, but let’s do a quick recap.

Visible light is electromagnetic radiation, just like any other forms of radiation, the closer you get to the source, the stronger the radiation. The colors of the visible light spectrum closest to the blue-violet side called Blue Light are of the highest energy. This Blue Light radiation is bad for your eyes and overall health. That’s why you need to keep a generous working distance to decrease your chances of blue light exposure. But unfortunately we are exposed to more and more forms of blue light radiation day by day.

So how could we protect our eyes from Blue Light exposure? The easiest solution is to wear a pair of glasses with special lenses which blocks Blue Light from reaching your eyes. Most of the lenses available in the market are anti-glare or anti – reflective. This alone does not protect our eyes from harmful blue light.

Anti-Glare / Anti – Reflective Lenses

Anti-Glare / Anti – Reflective Lenses are lenses with special anti-reflective coating (also called "AR coating" ) applied to the surface of lenses and other optical elements to reduce reflection. An AR Coated lens improves vision, reduces eye strain and makes your eyeglasses look more attractive with fewer distractions. It’s great for night driving also.

But does it really block the harmful blue light? The answer is NO. Normal AR coated lenses DOES NOT block the harmful blue light. AR coating virtually eliminate reflections from the front and back surfaces of your eyeglass lenses. With reflections gone, more light passes through your lenses to your eyes. More light means more blue light also. So, what’s the solution?

Blue Light Filter Coated Lenses

The good news is that, scientists have created an affordable coating for eyeglasses that helps block blue light. Ophthalmic  lenses with a special coating designed to reflect and cut high energy blue light penetration are now available in the market. This type of lens coating is referred to as a blue light filter coating. These lenses use a special coating to reflect a portion of the blue light emitted by digital devices and artificial light. This coating also incorporates scratch resistant and anti-glare benefits, giving you clearer vision while using digital devices.

All thanks to these latest blue light filter coatings, the harmful portion of blue light is cut while allowing the good portion of blue light to pass through. Due to the reduced amount of blue light entering the eyes, contrasts are improved by reducing screen brightness, flickering and eye fatigue to provide a strain-free visual experience while providing the most complete protection. Latest blue-light blocking lenses are clear lenses. Unlike the yellow-tinted blue blockers commonly used as computer glasses, these clear blue blockers do not distort colors.

It is important for you to maintain your eye health. Do consider blue blocking lenses for your next pair of eye glasses. By wearing blue blocking filter coated lenses, you experience less eye strain, headaches, and eye fatigue. It will also protect your circadian rhythms and ultimately your health.
