Blue light blocking glasses are the ideal protection against LED lighting; this omnipresent lighting in our environment emits peaks of blue wavelength rays.
Good to know: "traditional" tungsten artificial light mainly emitted red radiation.
Currently, LED lighting is everywhere at home, in the office, in public places, as well as in digital devices: mobile phones, tablets, televisions, computers...
Is blue light harmful?
Many studies link LED lighting to the alteration of circadian rhythms, which can negatively influence and weaken the immune system. It is also known that this light can inhibit melatonin secretion, making it difficult to sleep. LED lights are also said to affect serious diseases such as cardiovascular problems and certain types of cancer.
For your eyes, LED light can lead to computer vision syndrome (CVS) or eyestrain. Eyestrain can be caused by prolonged accommodative effort (the lens does not rest) and can occur in the following cases:
- We work in front of a computer screen or other digital device (mobile, tablet...).
- We read for hours without a break.
- We perform actions that require great concentration, such as driving.
- We are exposed to bright light: neon, LED, sunlight.
- We work in a place with insufficient lighting.
- We need prescription glasses but we don't use them!
This eyestrain can cause other symptoms:
- Blurred and sometimes double vision.
- Headaches, usually located at the temples.
- Dry eyes
- Itchy and burning eyes.
- Eye discomfort when exposed to light.
- Concentration problems.
- Red eyes.
- Glare.
Therefore, eyestrain generates symptoms that we associate with visual overexertion and lack of rest, but these discomforts can also lead to other problems. Therefore, if they persist, it is best to consult an ophthalmologist.
What about blue light glasses?
To protect our eyes from the potential harmful effects of blue light, blue light blocking glasses with specific protective filters for this type of lighting have been developed, their purpose? To reduce the intensity of blue and UV radiation. It's a simple and effective way to improve visual comfort.
Varionet opticians offer non-prescription blue light blocking glasses for children or those under 40 without visual defects, as well as computer glasses for presbyopes over 40.
