Get computer protective glasses with yellow lenses if you wish to enjoy viewing digital devices for long periods. However, various factors can lead to eye strain, so it is always advisable to seek medical/optical advice whenever possible.

Reduces Your Eye Disease Risk
Too much exposure to blue light can increase your chance of developing eye diseases such as cataracts. The blue light can penetrate through the cornea and then reach the retina.Indeed, it is true that your cornea and eye lens can block harmful UV light from reaching your retina, but they cannot block blue light. So, wearing blue light glasses can reduce the detrimental effects of constant exposure to blue light, which will reduce your risk of getting eye diseases.

Provides Better Sleep
Blue light can negatively affect your normal waking and sleeping cycles and the quality of your sleep. Moreover, blue light in the evening can hinder your body's ability to produce melatonin.Besides affecting your body's production of melatonin, blue light also disturbs your natural body clock. You may find it difficult to sleep at night and get up in the morning if your brain associates blue light with daytime. Likewise, you can minimize this effect by avoiding screen time 30 minutes before sleeping. As an alternative, putting blue light glasses on before sleeping while using your smartphone can also help mitigate the effects of blue light exposure.

Protects the Eyes From Dryness
Even though dry eyes sound like a minor issue, they can be very distracting when trying to concentrate or driving after a few hours of online gaming or working.

Types of Blue Light Glasses Lenses

Clear Lenses
Clear lenses block up to 40% of blue light and are ideal for relieving digital eye strain and improving focus during the day time. Additionally, these lenses may also be helpful to people who need to see true colors on screen or who wear a uniform at work.

And, that's because blue light also helps in keeping you active.

How to Test Blue Light Blocking Glasses?

Test Blue Light Glasses With An Image

The next test you can try is by looking at an image with a blue square and a black square. When looking at the two squares on a standard screen, the left one should be black, and the other should be blue.If you are wearing high-quality, functioning blue light blocking glasses, then they should look nearly identical. This is because the blue light showing from the screen is being filtered out, leaving only the black behind.

Use Blue Light Filtering Software

You can also try using some kind of blue light blocking software to test your glasses. Most devices have some way of doing this, whether it be night shift on Apple devices or the blue light filter on Android. You can also use a third party option like f.lux. Turn the software on and look at the screen without your glasses. Then, turn the software off and put your glasses back on. Depending on the setting of your software, the two images should look similar if not exactly the same.

Look At A Spectrum Report

Most companies that sell blue light glasses will have a spectrum report on hand that shows how much blue light the glasses actually filter. This is the only way to know for sure whether or not your glasses are actually blue light blocking glasses.In general, you want to make sure 30 percent or more of harmful blue light is filtered out.

The Benefits of Blue Light Lenses

Hormone Regulation

Exposure to blue light, particularly during the evening, has been shown to disrupt melatonin production, the hormone responsible for regulating our sleep-wake cycle. This disruption can lead to difficulties falling asleep and achieving restful sleep. Blue light lenses can help mitigate the impact of blue light by limiting how much reaches your eyes, supporting the natural release of melatonin and promoting a more restful and rejuvenating sleep.

Alertness

Blue light lenses can help signal to our bodies that it's time to wind down and prepare for a restful sleep. This, in turn, can contribute to increased alertness and productivity during the day, as we give our bodies the essential rest and rejuvenation they require for optimal performance. So, incorporating blue light lenses into our routine can be a valuable step towards achieving a well-balanced and energized lifestyle.

Depression & Anxiety Management

Research has consistently indicated a connection between disrupted sleep and susceptibility to depression and anxiety. Blue light lenses can effectively regulate our sleep-wake cycle and indirectly support mental health. These lenses promote healthier sleep patterns and overall well-being.Blue light lenses may contribute to improved hormone regulation and alertness and provide benefits for managing depression and anxiety.

The best way to clean Blue Light Blocking Glasses

The Lukewarm Water And Dish Soap Method
The reason why we recommend lukewarm water (aside from the fact that it dissolves dirt easily) is because water that has been heated becomes ‘soft water.' If the water that comes from your faucets is already soft water, then no need to worry. Soft water is water that has calcium chloride removed. Hard water contains minerals such as limestone, chalk or gypsum. which leave white stains when they evaporate. (Think of the white stains on your bathtub and on your taps.) You don't want that white powder clogging the crevices in your frames.

The Microfiber Cloth And Spray Method
For a less-intensive method of cleaning blue light, you can spray your glasses with an eyeglass cleaner and then wipe them off with a microfiber cloth. Eyeglass cleaners are cheap and you can find them anywhere- at the pharmacy, a grocery store or eyewear shops. If you're cleaning blue-light glasses which have an anti-glare coating, make sure that the cleaner you're using is safe to use on polycarbonate lenses and anti-glare coating. All of BlockBlueLight's daytime glasses and nighttime glasses have an anti-glare coating on them. Using the wrong cleaner could damage the delicate coating on your precious glasses!

The Steam Method
You can quickly clean your blue light glasses by allowing them to steam up from hot water and running a microfiber cloth over them. To do this;Run the tap with hot water until you start to see steam rise up.
Place your glasses near the steam and rotate them so that both sides of the lens fogs up. Don't place them under the hot water! Turn off the tap and gently rub your glasses in circular motions with the cloth, till they're squeaky clean!
