If the exposure to light is prolonged, these lenses help to protect your retina from damage as well as protect your eyes from any glare. The rays coming from digital screens are actually blue-violet rays and commonly they are harmful to everyone’s eyes. It is mandatory to protect the eyes because if your office work requires sitting in front of computer for too long, the retina of the eyes can be damaged. In the modern world, the concern about eyes and protection of eyes has been increasing.

It is a fact that nobody can avoid the screens now, but it is important to learn the ways in order to protect the eyes from the negative effects. Blue light typically comes from electronics links to many problems including, eyestrain, shortsightedness, blurry vision, macular degeneration, cataract, and dry eyes. Because of the short wavelength of blue light, the focus of the people’s eyes is not located in the center of the eye retina but located in the front of the eye’s retina, and because of this long exposure to blue light, the worsening of the visual problem occur called shortsightedness. Hence, a deficiency in blue light contributes to the increase in the shortsightedness in the people. The people can see the near objects clearly but distant objects appear blurry in short or nearsightedness. Blue light hurts people of every age. It does not matter whether you are young or old, it can affect at any age at any time.

  3. 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.

The daytime blue light filters or glasses are designed in order to reduce the harmful frequencies of rays and the light-sensitive cells can be protected with the help of using these glasses. 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

  2. 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. 


  3. Home Test

  4. 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. 


  5. RGB Color Circle Test

  6. 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.
