The answer to the question “do all blue light glasses have a yellow tint?” is no. However, it depends on how you wish to use your blue blockers and what you are trying to treat. Blue light is not something you just block, there is a bit more science to it than that. Whilst some blue blockers do have a yellow tint, many blue light glasses do not. Does this then render the blue blockers useless if they do not have a yellow tint? Definitely not, but each blue light filter has a purpose and they are not always yellow tinted. Let’s find out more.
There are three types of tint you can have on your blue blockers, let’s take a look at each tint and discuss when and where these different blue blockers should be worn.
Many blue light glasses now offer a clear lens which looks as though you are wearing regular glasses. The only difference is they may have a purple, blue or green reflection when someone looks at your blue light glasses. These blue blockers are often called computer glasses or anti fatigue glasses.
The purpose of computer glasses is to filter down blue light by between 5-30%. You cannot have a clear lens that filters any more than 30% of blue light. It just is not possible. So if you see a company advertising their computer glasses to be blocking 100% of blue light you know this is not possible and it is possibly a scam.
It is important to know that as humans we need some blue light exposure during the day. This blue light keeps us feeling alert, awake, happy and productive. The more blue light you remove during the day the less productive, happy and awake you feel. This is why it is good to remember that more blue light blocking during the day is not always better, in fact if you start blocking more than 30% of blue light during the day you may be doing more harm than good.
Computer glasses with clear lenses are worn during the daytime, when indoors an exposed to any source of artificial light. This could be from office lights, laptop, smart phone or your TV. They work by filtering blue light that causes digital eyestrain. Digital eyestrain is characterised by dry or watery eyes and headaches after using a computer during the day.
Not all computer glasses are created equal though. Ones that reflect purple or green light are not targeting the damaging blue light spike found in LED light sources. You can test your blue light glasses or find out more about this by reading our top-rated article on how to test blue light glasses.
Make sure you choose computer glasses that reflect blue light and you will be safely managing blue light during the day. The best computer glasses in Australia and probably the world is BluLite from BLUblox. These computer glasses are the best as they filter blue light unlike cheaper brands which filter purple or green light.
Yellow Tinted Glasses
Blue blockers with a yellow tint filter more blue light than regular clear lens computer glasses. Yellow tinted blue blockers will filter around 50% of blue light. When blocking more blue light during the day is not necessarily optimal for most of us, it will provide benefits to people who have an acute light sensitivity.
These people may suffer from migraines, Seasonal Effective Disorder (SAD), Anxiety, Depression or high levels of stress. Blue light during the day may cause a hormone called cortisol to increase in production which can intensify the symptoms of these disorders.
With this is mind it is therefore essential to block more blue light during the day than someone who does not differ from these disorders. This is where yellow tinted blue blockers come in. The best yellow tinted blue blockers are made by BLUblox and are called SummerGlo. These yellow tinted blue blockers block 50% of blue light and also have colour therapy infused into the lenses. The type of yellow tint used has been shown to improve mood and reduce stress in people with SAD.
Orange or Red Tinted Glasses
There is a third tint that is present in blue blockers. This is an orange, amber or red tint. These blue blockers can be classified as blue light blocking glasses. They are called blue light blocking glasses as they block 100% of blue light. The sad thing is most of these glasses do not block 100% of blue light as you can see from the spectrum test results article we wrote here.
The purpose of blue blockers with an orange or red tint is to help improve sleep. These glasses are not to be worn during the daytime as some blue light is essential for optimal health and hormones during the day. However, blue light has been shown by Harvard Health to disrupt our sleep and keep us awake. If you want to sleep better its essential to block all blue light and some green light. The magic zone of light to block is between 400nm to 550nm. This has been shown in this study from 2001 to be the exact range of light that disrupts our sleep when we are exposed to it after sunset. This zone of light is found in huge quantities in TVs, house lights, fridge lights, smart phones and our laptop computers.
By wearing the best blue light blocking glasses that filter 100% in this range you will get the most optimal sleep possible. Blue light glasses with a yellow tint or a clear lens will not help you sleep, you need a red or orange lens for this. The best blue light blocking glasses are made in Australia by BLUblox. Sleep+ are the best blue light glasses for sleep as they block 100% of the light that has been scientifically proven to disrupt sleep.
Do all blue light glasses come with a yellow tinted lens?
The answer is no. Whilst a yellow lens provides great benefits to blue light management they may not be the best option for you. If you work on a computer all day and have no sensitivity to blue light then the best blue light glasses for you would be clear lens computer glasses. If you work at a computer all day and have an acute sensitivity to blue light then yellow tinted blue light glasses would be a better option for you. If you want to sleep better and protect your circadian rhythm then you would be best placed choosing a pair of orange or red lens blue light blocking glasses and wearing these after sunset.
Blue light management cannot be found in just one lens as our light needs are so unique to each of us. Make sure you buy the best blue light glasses for your personal needs and always reach out to the company you wish to buy from first in order to have them help select the best pair of blue light glasses for you personally.
