Have you noticed that more and more people wear glasses? Sometimes even people who are not nearsighted or have vision problems use them. Blue light filter glasses have a lot to do with this. Let's see what they are and how they benefit our visual health.
Features of blue light filter glasses:
- They block the passage of blue light rays to the eye.
- They can be any eyeglasses, with any frame and design.
- They are compatible with other treatments, such as anti-reflective.
- They are compatible with lenses with monofocal prescription for distance, near, progressive and with any numbering.
Functions of blue light glasses:
The main function and advantage of these lenses is that they protect the eye from the entry of blue light.
What is blue light?
Blue light is a part of visible light, that which can be perceived by the eye, which is emitted at different lengths. Artificial light sources are those that emit the blue light wavelengths that are most damaging to the retina.
The percentage of blue light emitted by electronic devices such as mobile phones, tablets, computers or televisions is much higher than the percentage of blue light emitted by natural sources. Although to a lesser extent, another artificial source of blue light that impairs our vision is fluorescent tubes, used in many workplaces.
For this reason, the use of glasses with blue light treatment blocks the entry of these harmful rays and protects our retina from so many hours of device use.
Main problems caused by blue light:
- Fatigue and visual stress . 1 in 7 people suffer from it. It manifests itself with red, dry, tired eyes, headaches, a feeling of roughness when closing the eyes... This happens when we spend more than two hours in a row in front of screens, so the use of these lenses and intermittent breaks are recommended.
- Alteration of circadian rhythms , or what is the same, sleep disturbance. It happens because blue light reduces the synthesis of melatonin, the hormone responsible for sleep. By using screens before bed, our brain interprets that it is daytime and delays the onset of sleep.
- Age-Related Macular Degeneration (AMD) . It would be the most serious and serious problem. It is a disorder in the retina that prevents seeing in detail even reading.
Taking care of our vision before electronic devices is necessary to prevent major visual problems. You don't have to be myopic to protect your eyes with blue light glasses .
