About blue light

Blue light is simply electromagnetic energy that travels all around us in waves. These waves are a part of nature and appear in different forms such as infrared, microwaves, radio waves, ultraviolet light and the electromagnetic spectrum version which are gamma rays and x rays. Now while it is true that all these are forms of light energy, as humans, we do not interact with all of them and some are not even visible to the human eye. But not blue light.

Blue light has a very short but high energy wave that can impact human's vision. When exposed to the human eye for an extended period, it can damage vision. And there are different sources of blue light which include:

· Sun

· Fluorescent bulbs

· Incandescent bulbs

· Flat screens

· Laptops

· Cell phones

· Computer screens

Of all these blue light sources, you will agree that we interact more with blue light in the gadgets that we use. Today, our display screens have an excessive amount of blue light actually.

The human eye has protective structures that keep out some light spectrum but not blue light. This is why excessive exposure to blue light can have adverse effects on the health of our vision.

Where does blue light easily hurt you?

There are many occasions where the person can expose to damaging the retina of the eyes because of long exposure to blue lights. 

1. Prolong Computer Screen Exposure

Digital screens including computer screens emit blue light which can definitely have a negative impact on the eyes of the person using the screens. Blue light not only affects the eyes but also sabotages the schedule of sleep as it messes with the rhythm called "circadian rhythm" (Sleep wake cycle). 

When the person is sitting on the computer for so long, including day and night and he does not get good sleep, blue light easily hurt him because of the prolonged exposure to the digital screen.

2. Prolong Smartphone Screen Exposure

Nowadays, people love to entertain themselves with the help of playing games on smartphones as well as indulge in different social media gossips. They used to open and be exposed to the screen of smartphones for too long and what's worse, they even forget to sleep timely. This exposure to blue light screen is harmful to the eyes and thus, the vision problem can occur at any moment.

3. LEDs Screen Exposure

These days the usage of LEDs in many houses has become common and people love to listen to the news as well as different TV shows on the screens. 

It is a fact that when people are staring at the screen that produces blue light, and they don't blink their eyes for so long, the eyes become dry and this dryness of the eyes is really problematic for all people. This means that blue light has affected the retina of the eyes and the person can get nearsightedness or any other eye condition. Hence, blue light can easily hurt those people staring at the screens for so long. 

What are blue light lenses?

In order to reduce the damage and protect the eyes from blue light or digital light, blue light lenses have already been introduced to the world. These crafted lenses are used in the blue light glasses and helps block the light coming from the television, computer, tablet screens, smartphones, etc. 

Over the past few years, the usage of these lenses has risen. The lenses are designed in such a way that the relief can easily be provided from those side effects which are uncomfortable basically associated with staring at the computer/tablets screens for so long.

How does blue light blocking glasses work?

To combat the harmful effects of blue light, experts advocate the use of blue light blocking glasses; but how do they work?

These specialty glasses have a special coat that covers the lens. This coat has filtering materials that block some of the light coming from your device. To be fair, the coat doesn't block out blue light completely otherwise you will not be able to see at all.

However, by reducing the light intensity that enters your eyes you are spared its harmful effects. The sole purpose of wearing blue light blocking glasses is to reduce exposure significantly.

The benefits of blue light glasses

Here are blue light glasses benefits you should be aware of.

1. Reduce water and dry eyes

If you suffer from watery eyes or dry eyes after staring at your phone or computer screen for a very long time, you definitely need blue light glasses. By wearing one each time you use your device, you will not have to deal with the condition due to the ample protection the eyeglasses provide.

2. Reduce light sensitivity

If you are extremely sensitive to light, you definitely need blue light glasses. The coated lens will filter out the excess light so your eyes will not react to it.

3. Eliminate blurred vision

Suffering from blurred vision? One of the positive effects of using blue light glasses is that they improve your vision by making images and text clearer. No longer should you have to squint to draw near to your screen to see clearly.

4. Eliminate Headache

Another benefit of blue light glasses is the reduction or elimination of headaches caused by excess light from digital devices. Some people develop headaches after staring at their screens for some time. If you suffer headaches as well, you should get one and wear it at all times when you use your devices.

How to buy the right blue light glasses?

To summarize, these are the most important considerations to keep in mind while selecting the proper lens colour for your blue light blocking glasses:

1. The maximum per cent blockage figures stated above are based on colour science, not industry standards. Bigger percentages may be released in the future. 

Unfortunately, there may be some marketing at work here, with businesses creating their scale (similar to SPF ratings for sunscreen) and claiming that their lenses block more light than they do.

2. If at all possible, avoid wearing orange lenses. They used to be regarded to be the most effective, but research has shown that the body has a master clock and natural circadian rhythms that ebb and flow. 

To keep these cycles in line with the natural rise and fall of the sun, the body requires varied quantities of blue light during the day and almost no light at night. As a result, having one set of blue light blocking glasses for the day and one pair of "sleep-hacking" spectacles for the night is more successful.

3. For the hours coming up to the night, red lenses are the most effective alternative. Because red is the lowest impact hue that covers the largest spectrum of junk light, even the military has switched from orange lenses and interfaces to red ones. This is especially true for those who work night shifts, which military personnel frequently do.

The blue light blocking glasses are very helpful in the way that they help us stay focus as well as alert, regulate the circadian rhythm, and at the same time keep us productive at work. 

1. Transmittance Spectrum Report

To make sure the glasses you have purchased truly block the blue light, you need to test or ask the seller about the transmittance spectrum report which helps to show off the light percent typically passing through the blue light blocking glasses lens. Remember that the glasses should filter down approximately 30% of blue light across the entire range. You can also conduct different tests at home. 

2. Home Test

Put the blue light blocking glasses and observe the color that is given reflection. If the reflection of the lenses is purple, this means that the lenses are not filtering out the blue light. If the color is blue, this is a good indication of good filtering. 

3. RGB Color Circle Test

In the RGB color circle test, you need to test the LCD (Liquid Crystal Display) used in digital devices. The screens have many pixels and the colors of the pixels are blue, green, and red. The variations of these colors can be seen. Put on the blue light blocking glasses and check out the model of RGB color. It is an interesting fact that the blue and green parts of the main image appear black or darker. 

Remember, the darker the color is, the filtering of blue light is more and more. Therefore, if you watch screen for long time everyday, the blue light blocking glasses are highly recommended. Try to place an order of a pair of blue light blocking glasses.
