![]() Depending on your requirements and time of day, you should go for blue light glasses which at least block 90% of blue rays. Most brands specify the percentage of blue light their glasses block. On the other hand, too light of a pair will not be strong enough and will break on impact.

Here are the factors which determine the comfort of your blue light glasses. ComfortĬomfort is perhaps the most significant feature to look out for when you are buying any type of eyewear. A possible solution to this problem is to wear contacts along with a normal pair of blue light glasses. Second, blue light glasses offer a range of magnifications to suit your prescription requirements however, similar to reading glasses, blue light glasses offer the same magnification in both lenses which might not be suitable for a lot of people. So, if you do want to try out blue light glasses, you will have to buy a new pair. First, the blue light filters cannot be added or incorporated into lenses after they are made. There are two main things you need to consider if you already wear a pair of prescription glasses. Factors to Look For in the Best Blue Light Glasses Prescription requirements There is also adequate evidence that showcases that blue light glasses also ensure a deeper sleep. This supports normal melatonin production and leads to a normal sleep-wake cycle. Blue light glasses prevent our eyes from sending signals to the hypothalamus that it is daytime by potentially creating a darker illusion of the environment around us. Improved sleepĮven though reduced eye strain is a possible benefit of blue light glasses, an improved sleep cycle is a more apparent benefit for most people. Although there is insufficient evidence to support the fact that these symptoms are caused by exposure to blue light, people do have a more comfortable screen viewing experience with their blue blockers on. Working overtime in front of a screen can lead to eye fatigue, blurred vision, and drier eyes. What Are the Advantages of Blue Light Glasses? Reduced eye strain To achieve this, some blue blockers are layered with a substance known as melanin which gives the lens a brownish-yellow hue. A decent pair of blue light glasses must block at least 90% of blue light. Blue light glasses are coated with certain substances to block this potentially harmful blue light. Even though the wavelength of blue light ranges from 400-465nm, the most damaging of the spectrum can be the wavelengths in the range 415-455nm. How Do Blue Light Glasses Work?īlue light glasses function by blocking or filtering blue light which passes unchecked through your cornea and lens, reaching your retina. Therefore, being overexposed to blue light and at the wrong times can lead to disrupted sleep cycles and possible eye damage. However, working on your computer throughout the day or doom scrolling on your phone at night leads to the suppression of melatonin production by the brain which can severely disturb the quality of your sleep. ![]() This can help you greatly during the day when you need it. When you are exposed to the high-energy, bright blue light, your mind awakens and cognitive functions sharpen for greater productivity. Our bodies have internal clocks which dictate the circadian rhythm. The time of exposure refers to two factors: the amount of time being exposed to blue light and the time at which you are being exposed to blue light. This helps minimize the damage that blue light can do to your eyes. To further elaborate on the type of exposure, it is easy to see that sunlight consists of the entire visible spectrum, unlike our crisp, mostly blue light-emitting screens. However, how that exposure differs from the blue light emitting from your screen can be explained in two ways: the type and duration of exposure. A plausible question that might pop up in your mind at this point is this: as blue light is a part of the visible light spectrum, are we not exposed to it during the daytime when the sun is out? The answer is yes.
