Blue cut: new technology for ophthalmology
If you are always updating your lenses to the latest technology, you should try blue cut glasses. The dependency relationship with electronic devices causes health problems due to overexposure to blue light.
Using glasses with a blue block filter you will be able to mitigate the damage caused by this light spectrum.
What is the blue cut?
The blue cut is a technological coating that is applied to the surface of the lens, whose function is to filter the blue light coming from the outside. Blue block lenses can be distinguished from common ones because they have a slightly sepia color.
This shade belonging to yellow helps neutralize the impact of blue light on the eye. Additionally, it provides the user with a natural lighting appearance. Thus, it is possible to reduce the excessive brightness of the LED lights on the screens on the retina.
Blue block glasses filter light by blocking a type of wave more intense than others called blue light. Although the sun naturally radiates very powerful rays of blue light towards the earth, they are not that harmful.
The reason is that we are not as exposed to the sun as we are to electronic devices. The symptoms of insomnia, tiredness, redness and eye fatigue come from the indiscriminate use of screens. Consequently, it is necessary to protect the eye with blue cut lenses.
How is the blue cut used in current ophthalmology?
Blue block lenses are especially indicated for people who have mandatory prolonged exposure to computers, tablets and smartphones. This is the case of those who work remotely or have an office job that requires looking at the computer for more than 8 hours.
However, the blue cut is recommended by ophthalmologists for the majority of Internet users, even for those with perfect vision. According to the Official College of Opticians and Optometrists of Catalonia, in 2019 the population spent an average of 10 hours in front of a screen. Therefore, these lenses are prescribed for everyone.
In short, if you spend many hours in front of the computer or mobile phone, you should purchase blue light glasses. Eye doctors warn that blue cut glasses are not effective by themselves. Changing habits regarding screen use is key to reducing the negative effects of this spectrum on health.
