How do blue light glasses work?


Blue light glasses have become increasingly popular in recent years, as more people spend long hours staring at digital screens. These glasses are designed to block or filter out blue light, which is believed to be harmful to our eyes and sleep patterns. But how do blue light glasses actually work? Let's take a closer look.

First, it's important to understand what blue light is and where it comes from. Blue light is a type of light that has a short wavelength and high energy. It's present in sunlight, as well as in the screens of electronic devices such as smartphones, computers, and televisions. In fact, these devices emit more blue light than any other source.

Blue light has been linked to a variety of health problems, including eye strain, headaches, and disrupted sleep patterns. Some studies have even suggested that prolonged exposure to blue light may increase the risk of certain types of cancer. This is why many people are turning to blue light glasses as a way to protect their eyes and improve their health.

So how do blue light glasses work?

There are two main types of blue light glasses: those that block blue light and those that filter it out.

Blue light filtering glasses

Filtering blue light glasses, also known as blue light filters, work differently from blocking glasses. These glasses have lenses that allow blue light to pass through, but filter out certain wavelengths of blue light that are believed to be the most harmful.

Filtering blue light glasses are often clear or have a very slight yellow tint, which makes them more subtle than blocking glasses.

Baxter Blue uses their exclusive Blue+ ™ technology in their lenses. Unlike their competitors, their blue light filter is not a surface layer or coating. Baxter Blue's lenses have a blue light pigment technology embedded right into the lens, filtering out as much as 80% of the highest energy wavelengths known to cause digital-eye-strain.

Blue light blocking glasses

Blocking blue light glasses, also known as blue light blockers, are designed to completely block blue light from entering your eyes. These glasses have lenses that are made from special materials that absorb blue light before it reaches your eyes. Some lenses may also block other types of light, such as UV rays.

Blocking blue light glasses are typically amber or orange in color, which can take some getting used to. However, many people find that the benefits of reduced eye strain and better sleep patterns are worth it.

In conclusion - Blue light glasses can be a great way to protect your eyes and improve your overall health, especially if you spend a lot of time in front of digital screens. Whether you choose blocking glasses or filtering glasses, be sure to choose a reputable brand and check that they have been tested and approved by a reputable organization. And remember, while blue light glasses can be helpful, it's also important to take regular breaks from screens and practice good eye health habits.
