Blue light glasses work, when they filter what the peer reviewed academic literature states they should. Many blue light glasses do not work so make sure you read our article on how to choose the best pair of blue light glasses after you finish reading this article to determine if you need blue light glasses in the first place.

In this article we will give you 10 compelling reasons you may need blue light glasses. As our light needs change throughout the day and into the evening we have divided the article into two clear sections. The first section will provide advice on whether you need computer glasses, these clear lenses will filter blue light during the day as it’s important not to bock blue light at this time. The second section will address whether you need to wear Sleep+ glasses after sunset, which are red lens blue light glasses and the best blue light glasses to wear.

How do I know if I need blue light glasses for during the day?

  1. You have blurred vision at the end of the day

Blurred vision is a symptom of digital eye strain which is caused by overexposure to blue light from your computer screen or office lighting. If you work long hours at your computer or in an office with artificial lighting you are more susceptible to blurred vision and digital eyestrain each day. Don’t ask too much of your eyes and protect them with computer glasses that filter down blue light.

  1. You spend more than 8 hours looking at a screen

In today’s digital world it’s hard not to spend less than 8 hours looking at some sort of screen. Whether it be our computers, TV or smart phone our eyes are glued to something digital. When our eyes look at a screen we are exposing them to isolated blue light which means over time we will be damaging them. This is why wearing blue light glasses which filter blue light are worth the investment as they will help reduce some of the blue light from hitting your eyes. We don’t have to give up our technology we just have to protect our eyes when using it.

  1. You get headaches during the day

Whilst many things can cause a headache, blue light is one of them. Blue light from overhead office lighting and your screens causes something called digital eyestrain. When we strain our eyes working under artificial light it can create a tension headache which can be very uncomfortable. By filtering out specific frequencies of blue light from passing through our eyes we can cut down the headaches and feel our best selves again. Remember to read our other article on how to pick the best computer glasses to make sure you get the correct blue light glasses to help your headaches.

  1. You have trouble concentrating

Losing concentrating is another symptom of digital eyestrain.  Losing focus is one of the first signs of digital eyestrain so if you work in an office with screens you may wish to consider investing into some good quality computer glasses.

  1. You get watery eyes when working on a computer for a long time

Many people think that dry eyes are the only eye related symptom of digital eye strain but this is false. People can get very different symptoms and one of those is watery eyes. If you are getting watery eyes it means your eyes are sensitive to blue light and investing in a pair of blue light glasses may help manage this.

How do I know if I need blue light glasses for after sunset?

  1. You do not sleep well

Exposure to blue and green light between the scientifically backed melatonin disruption zone of 400-550nm disrupts our sleep. If you are not getting good quality sleep you have a higher risk of circadian mismatch diseases such as obesity, diabetes and heart disease. By wearing blue light blocking glasses that block 100% of light between 400-550nm you will improve your sleep. Read more about choosing the best blue light glasses.

  1. It’s hard to get out of bed in the morning

Finding it hard to wake up or get out of the sack in the morning is a sign of a disrupted sleep and circadian rhythm. Poor sleep is caused when blue light and green light after sunset tricks our brain into thinking its daytime and to not sleep optimally. Therefore, by wearing blue light glasses that have a red lens after sunset will block these frequencies of light, allow you to get a solid night’s sleep and spring out of bed in the morning. Doesn’t that sound great?!

  1. You have no energy or you slump during the day

Poor sleep doesn’t just increase all cause mortality rates, it saps us of our energy throughout the day. By improving your sleep by managing both blue light and green light after sunset will ensure you get improved sleep and energy levels the next day.

  1. You watch TV, have lights on and use your fridge after sunset

Your TV, house lights, fridge, appliances, neighbours, street lamps, car headlights, Wi-Fi router, laptops and smart phones all emit sleep destroying blue light. If you want to use these things after sunset and not disrupt your sleep it’s time to invest in a pair of blue light blocking glasses that have a red lens and focus on blocking all blue and green light between 400-550nm.

  1. You are trying, but failing, to lose weight

Weight gain is not just a story of calories in vs calories out, it’s how our body stores the types of food we eat. By exposing ourselves to blue light after dark we risk having increased insulin and blood sugar levels which means the food we eat will be stored as body fat. By wearing blue light glasses after sunset, we may be able to regulate blood sugar and insulin levels and store less of the food we eat as body fat. If you are trying to lose weight give yourself that extra edge with a good quality pair of blue light glasses.
