FAQs About Blue Light Glasses

What is blue light?

All of the light the human eye can see falls somewhere on the visible light spectrum. Each color of light has a different wavelength, with blue light being on the low end of the spectrum, between 380 and 500 nanometers.

Light with shorter wavelengths, like blue light, has higher energy. This is why we refer to blue light as High-Energy Visible light (HEV).

While the largest producer of natural blue light is the sun, devices like laptops, smartphones, tablets, and even LED lighting all emit blue light. Many people spend countless hours a day staring at digital screens for both work and entertainment. For this reason, eye doctors are concerned that overexposure to blue light may be causing symptoms of eye strain and even sleep disruptions.

Is blue light bad?

Yes and no. Blue light is a naturally occurring light that our body needs to function. The blue light we get from the sun is what helps our bodies know when we should go to sleep, and when we should wake up in the morning. It is one of the primary elements that help regulate the circadian rhythm (the body’s sleep cycle).

While some blue light is necessary for our body to function properly, too much blue light may cause problems like eye strain, eye fatigue, headaches, disrupted sleep, and even insomnia.

In more extreme cases, some studies have found that too much blue light can affect your mental health.

What are blue light glasses for?

Blue light glasses are glasses that contain specially crafted lenses that block or filter out the blue light emitted from digital screens.

How do blue light glasses work?

Blue light glasses have lenses that block or absorb blue light, thus preventing blue light (and even sometimes UV rays) from reaching the eyes.

How can I tell the difference between all of the blue light glasses available on the market?

With so many options available today, it can be difficult to decide where to purchase your blue light glasses from.

To ensure you are purchasing quality lenses, look for blue light glasses that filter up to 80% of High Energy Visible (HEV). Ideally, your lenses should offer glare protection and UV protection as well.

Avoid lenses that are orange-tinted or claim to block 100% blue light. Your body needs to be exposed to some blue light for your circadian rhythm to function properly.

Can blue light glasses help you get more sleep?

Blue light glasses shield your eyes from the blue light emitted from our digital devices and other artificial light sources. By doing this, it becomes easier for your body to produce melatonin, the natural hormone that makes you feel tired.

Do blue light glasses help with eye strain?

Yes, blue-light-blocking glasses are designed to reduce eye strain and visual fatigue.

While more extensive research is needed to know exactly how much blue light glasses help with digital eye strain, some individuals have found them to be helpful. Customers who wear blue light glasses all day long have reported that their eyes feel less tired at the end of the day.

Can you wear blue light glasses all day?

Yes, bluwinx blue light glasses are made to wear during the day and at night.

In addition to filtering out the blue light emitted from digital devices, blue light glasses can also help reduce glare from oncoming headlights and street lights when driving at night. 

How can I tell if my lenses have blue light protection?

If you did not specifically request blue light blocking lenses when you purchased your current pair of glasses, they likely do not offer blue light protection.

Most of the time, blue light lenses are an upgrade when buying from your local store. When you order from a company that specializes in blue light glasses, like bluwinx, your glasses automatically come with blue light blocking lenses. With over 100 styles available, you don’t have to compromise your look to get a pair of glasses that look great but also keep you protected.

Who should wear blue light glasses?

Anyone that spends long hours on the computer or other digital devices might want to consider wearing blue light glasses. Additionally, individuals who experience digital eye strain or difficulty sleeping may also benefit from wearing blue light glasses.

Can blue light glasses be fit with my prescription?

Yes, all blue light glasses on the bluwinx website can be fit with your prescription. Once you have selected your frames, simply choose “I’ll enter my prescription now” from the drop-down menu.

If you already have prescription glasses, you may ask your eye doctor or local eyeglasses store if your lenses can be replaced with blue light filtering lenses.

What are other ways I can protect my eyes from blue light?

Other ways you can limit blue light exposure include:

  • Reducing the amount of time you spend using digital devices
  • Setting your laptop or phone to “Night Mode”
  • Not looking at digital screens at least one hour before bed
  • Practicing the 20-20-20 rule where every 20 minutes you spend looking at a screen you look at something 20 feet away for at least 20 seconds
