What Kind of Glasses Block Blue Light?

We live completely surrounded by screens, spending an average of almost nine hours a day in front of digital devices. Digital devices emit blue light, and overexposure to blue light can cause harmful effects to your eyes. Some of the potential side effects people experience are eyestrain, headaches, difficulties focusing, difficulty falling asleep and insomnia, sleep disturbance, etc.

Blue light blocking glasses are a brilliant tool for those who stay constantly on the screens. If you search for “blue light” on the internet, you will see a lot of research and information about how they can be harmful to your eyes and your overall health.

Therefore, let’s focus on which type of glasses is the best solution for you.

Which type of lens blocks blue light?

The percentage of blue light blocking glasses varies from lens to lens. Let’s take a closer look:

Clear lenses
Clear lenses block between 30-40% of the blue light spectrum. Maybe they can be useful in slightly relieving your eyes during the day. However, if you are spending hours in front of your device, they are not the best option. You need higher protection in order to keep healthy eyes.

Yellow lenses
Not all yellow lenses are the same. Some block around 50% of blue light, so if you work from home or you are spending hours in your office, this should be more than sufficient to get the right protection for your eyes.

Orange and red lenses

Orange and red lenses block typically 98-99% blue light. Orange lenses were developed by NASA, based on science1 in the 1970’s. They provide far greater protection, but for some people, the tint can be distracting. These lenses may also distort color.

Differences in color lenses

Your lifestyle, your work, hobbies, and other activities, play an important role in deciding which type of lens to buy. Each colored lens has the same purpose - to improve and enhance your eyesight. At the same time, some of them may disrupt vision, distort colors, reduce visual acuity, and so on.

However, when you try purchasing colored lenses, try to evaluate different types and compare their advantages and disadvantages. All the lenses mentioned above can be more or less suitable for someone. Some people don’t prefer too many colored tints on their lenses, while some glasses are better to wear at daylight or night.

On the market, there are various blue light blocking glasses that range in price. If you want to buy high-quality blue light blocking glasses, consider several things such as frame and lens material, percentage of blue light being blocked, and other specifications and lab tests results.
