Do Blue Light Glasses Work

If you’ve ever worried about the effect of digital screens on your eyes, then you may have heard about ‘blue light’, and perhaps even searched for ways to protect your eyes against it. Blue light glasses (or blue light blocking glasses) are becoming more popular than ever due to claims that they can protect your eyes against potential damage -- but how effective are they at keeping your eyes healthy?

Daily Blue Light Exposure

If you have a digital-based job, you probably stare at a computer screen or laptop all day, which means your eyes are doing overtime. Even outside of working hours, harmful blue light is emitted from the screens on our smartphones, tablets, and TVs, so it’s hard to switch off.

The average person consumes around 10 hours of screen time per day, so blue light glasses are well worth thinking about to ease the pressure on your eyes. They make long hours in front of a computer, gaming on a console or PC, or simply watching TV less strenuous for your eyes.

Blue Light Blocking Glasses

Blue light blocking glasses can help reduce eye strain. Blue light can make it difficult to focus on the screen, making your eyes strain to concentrate. Blue light glasses also help increase contrast on your screen, making it easier to focus and subsequently reduce eye strain. 

What is the Best Material for Eyeglasses

It’s time to choose a new pair of eyeglasses, and the current selection of frames is overwhelming. Armed with only your vision prescription, you now need to navigate between different materials, colors, prices and unique features of all the eyeglass frames. Here is a basic guide that explains about the most common types of frames and what they have to offer.

Titanium

You’ve probably heard of titanium described as a sort of super material, and when it comes to glasses, it fits the bill. Titanium is an extremely strong, lightweight metal that’s well-suited for eyeglass frames. Its silver coloring is attractive and titanium doesn’t corrode.

Titanium can also be made into a memory metal, meaning it can flex and return to its original shape. That “give” is a perfect attribute for eyeglasses. If you have a history of leaving broken frames in your wake, titanium could be the perfect material for you.

Acetate

A plant-based plastic that is hypoallergenic. This material was first used for eyewear in the late 1940’s because of brittleness and other problems with previously used plastics. Nowadays, acetates are known for being strong, lightweight, and flexible. Acetate also has the widest range for transparency, rich colors, and finishes. More complex colorations are able to be produced by layering several colors or transparencies in layers and sandwiching them together.

Metal

A more affordable alternative to titanium, metal is strong and won’t easily rust or corrode. For these reasons, many eyeglass manufacturers use metal in their frames. Metal lacks the “memory” property of titanium but is much more resilient than plastic.
