Do you spend hours in front of the screen? Daily exposure to large amounts of blue light radiation from artificial sources, such as your computer, phone, tablet, TV, or similar devices that you use regularly, can negatively affect your eyes, as well your overall health. If you want to reduce the negative impact of the harmful blue light, then blue light blocking glasses are what you need. Computer blue light glasses have lenses of patented technology for protection against blue light radiation that digital devices emit. In this text, we will try to address questions such as what is blue light, where does it come from, and how does it affect the body and our eyes?
What is blue light?
Sunlight is a natural source of blue light. Blue light is the high-energy visible part of the spectrum. However, today we are much more exposed to blue light than before, which comes from artificial sources such as digital device screens from mobile phones, tablets, and TVs. This is the harmful blue light that has negative effects on our eyes and health. One such harmful effect is that blue light affects the secretion of melatonin, a hormone that controls the day-night rhythm, and sleep.
According to the basic wavelength, blue light can be divided into:
- Blue-violet light (415-455 nm), which can lead to retinal damage and consequent macular degeneration
- Blue-turquoise light (465-495 nm), which has positive effects on your eyesight and health, and is used in the treatment of sleep disorders
The impact of blue light radiation on your eyes
When blue light reaches your eye, it passes through the cornea and reaches the retina. Although our eyes are designed to withstand blue light well, we still have too much contact with artificial blue light. This can lead to the following conditions and disorders:
- Sleep disruption
Blue light affects the production of hormones in the brain, positively or negatively. An example of a negative impact is reduced melatonin production1. Exposure to blue light emitted by the device reduces the secretion of melatonin, which equally affects the quality and duration of sleep.
- Dry eye
Tears on the surface of the eye form a thin tear film that maintains eye moisture. Research shows2 that blue light can impair tear film stability and make your eyes irritated and tired. Blue light can cause dry eye indirectly by keeping you awake for a longer period, which over time can cause dry eye syndrome3.
- Macular degeneration
There is evidence4 in medicine that exposure to blue light can cause eye-related conditions. Blue light contributes to damage to the cells in the retina, which can cause macular degeneration. Our skin, hair, and eyes contain melanin, a substance that absorbs harmful blue light. As we age, the melanin levels decreases, which makes us more susceptible to eye diseases.
How do blue lens glasses protect against blue light?
The human eye is unable to filter this type of light and almost all visible blue light reaches the cornea, which can have various consequences. Computer glasses have a special coating that prevents blue light radiation from reaching your eyes and thus significantly reduces the unpleasant symptoms it causes.
Thanks to that, when using these computer glasses, despite the significant time spent in front of the screen, your body will function more in accordance and balance with its natural cycles.
