Computer Glasses- All You Need To Know

What is blue light?

High-energy visible (HEV) is commonly called blue light and makes up approximately one third of all visible light and is actually what makes the sky blue. The main source of blue light is sunlight. However, the screens of our computers, tablets, smartphones and other digital devices emit a prominent amount of blue light. The amount per say, isn’t enough to cause any damage, but the amount of time spent in front of screens as well as the proximity to our eyes is what may have a negative effect on our eye sight. Blue light blocking lenses help the eyes filter out this harmful light and ease the strain on the eyes.

What are blue light blocking glasses?

If you, like most of us, spend the majority of your day in front of a screen, you might need blue light filter glasses to relax your eyes from digital eye strain, also known as computer vision syndrome. Blue light glasses protect your eyes from the blue light emitted from the screens without affecting your vision.

Do I need blue light glasses?

Blue light glasses featuring blue blocking lenses, are as the name suggests, available for the sole purpose of blocking blue light from digital screens such as computers. These are thereful suitable for those who don’t require any vision correction or wear contact lenses. However, blue blocking lenses are also suitable for those who need prescription eyewear for presbyopia and wear reading glasses, progressive lenses or bifocals since blue light glasses lenses are great for people who have visual impairments at intermediate distances and want to achieve a sharper focus and enhanced visual clarity.
