What to look for when buying blue light computer glasses?
Computer glasses are blue light filtering glasses that have a clear lens. They are to be worn when working at a computer or under artificial light sources during the day. Blue light computer glasses will not improve your sleep, they target filtration of artificial blue light which causes digital eyestrain, headaches and macular degeneration.
Below is a list of what to look for when buying blue light computer glasses:
- What colour does the lens reflect?
- What percentage of blue light does the lens filter?
- Where were the blue light computer glasses made?
- How stylish are the frames?
- What frequencies of blue light do the computer glasses filter?
Let us take a look at each of these individually.
What colour does the lens reflect?
When it comes to buying blue light computer glasses knowing what colour of light is being filtered is very important. Blue light is emitted during the day from LED back lit digital devices such as your smart phone, computer, TV and office lights and damages your eyes to produce digital eyestrain or macular degeneration. These issues are caused by blue light but many companies who sell blue light computer glasses target violet light. Violet light is not found in significant quantities in these devices meaning if your blue light computer glasses target violet light they are not going to provide optimal protection for you. When you look at pictures of your chosen blue light glasses, if you have not purchased yet, or look at your current blue light glasses, what colour of light is reflected when you hold them up to an artificial light source? If the colour reflected is green light or violet light you know you do not have a good pair of blue light computer glasses.
If your blue light filtering glasses reflect blue light you are off to a good start which means you can be confident you are targeting the actual light found in digital back lit LED devices. You can also test your blue light glasses by reading this article here or by watching this video.
BLUblox BluLite computer glasses filter blue light and are considered a great option for blue light computer glasses for daytime use.
What percentage of blue light does the lens filter?
Knowing how much blue light is filtered is key to getting the best blue light computer glasses and important information to know when looking to buy blue light computer glasses.
This next piece of information is very important. Blue light is essential during the day, we need blue light to be optimal and active during the day. Therefore, more is not better when it comes to blue light management during the day. There is a sweet spot and that is around 30% of blue light filtration between 400nm and 495nm. Our customer service department gets a lot of questions each day around why are blue light filtering computer glasses “only” filter 30% of blue light when other companies claim their clear blue light glasses block more blue light. In all comes back to the important information above, more is not better in terms of blue light filtering during the day. Our circadian rhythms need blue light during the day to optimise hormone production. If we filter too much blue light during the day we will damage our hormones and disrupt our body clocks. 30% is the sweet spot for most. BluLite computer glasses filter 30% of blue light.
30% if the sweet spot for most in terms of blue light to filter when buying blue light computer glasses. However, there is an exception. Those who have light sensitivity issues would benefit from 50% filtration and colour therapy. This is where SummerGlo lenses come in to play. The yellow lenses on these blue light blocking glasses are great for people who suffer migraines, have anxiety or suffer from depression, during the day. By targeting a little more blue light, whilst still leaving some blue light present to optimise hormones, SummerGlo lenses combine colour therapy with blue light blocking to created boost booster blue light blocking glasses.
Where were the blue light computer glasses manufactured?
This is another important consideration when buying blue light glasses. Where the glasses were manufactured will often be a good indicator of quality. For example, most brands who sell cheap blue light blocking glasses have them mass produced in Chinese factories with next to know QC process. This means you will get exactly what you pay for, cheap materials, sub-standard lenses and often faulty frames. BLUblox blue light computer glasses are manufactured under optical laboratory conditions with a three tired QC process. The frames are made from the finest materials and the lenses used are premium optical grade, meaning sharpening of vision. The other issue with mass produced blue light glasses in factories is the conformity of each lens. Many of the lenses will differ from the next meaning you may not be getting the same product as advertised. Make sure you consider where the blue light glasses are being made before purchasing as it will often determine the quality. When you invest in blue light glasses, opting for the cheapest is not always the best buying strategy.
How stylish are the frames?
This does not relate to the blue light filtering technology but the style of frames is super important when you are thinking of buying blue light computer glasses. You are going to be wearing these blue light blocking glasses in your office all day, in front of your peers, you are going to want to look the business. At BLUblox our latest collection has been modelled on our work with Vogue, QG and Elle and are up with the latest trends. Check them out here.
What frequencies of blue light are being targeted?
Back to the lenses and science. All LED light sources during the daytime are spiking in blue light between 440-460nm therefore is makes sense that when you look to buy a pair of blue light computer glasses they target this area. Many cheap pairs filter violet or green light so when you contact the customer service teams or look on websites to buy blue light glasses you see what frequencies of blue light are being targeted. BLUblox BluLite computer glasses filter down blue light is this range, giving you the confidence that they are not only super stylish but also completely backed by evidence and science.
