Most of the time, your eyes are stuck to the laptop screen for the whole day at the office. In between writing reports, you browse your phone. When you get home, you turn on the TV in time for the 6 o’clock news. And before dozing off, you watch videos on your tablet.
No doubt about it, everyone’s day revolves around electronic devices. While these devices make life and work more comfortable, they emit blue light that is harmful to health. Good thing, there are Blue Light Blocking glasses that can protect from this dangerous light.
What is Blue Light?
There are different colors with varying wavelengths in the visible light spectrum. Since blue light is located towards the end, it has the shortest wavelengths. Physics dictates that the shorter the wavelength, the higher the energy it emits. Blue light is also called high-energy visible or HEV light.
Sunlight is a natural source of blue light. Exposure to natural sunlight signals the body to wake up in the morning. It boosts alertness and cognitive functions.
But with the digital lifestyle that people are living nowadays, there is just too much exposure to artificial blue light, which is harmful to health. LED lights, computer monitors, phones, and tablets are sources of artificial blue light. Prolonged exposure to these devices can cause a variety of illnesses and problems.
What are Blue Light Blocking Glasses?
Blue Light Blocking glasses have a slightly-tinted yellow lens that blocks 50 % of artificial light. Since all HEV light can penetrate the retina, these glasses are needed to protect our eyes from damage.
Benefits of Wearing Blue Light Blocking Glasses
- It Increases Melatonin Production
Melatonin is a hormone responsible for controlling the daily rhythm of the body. When it is already dark, the body releases melatonin. Whereas when the body hits natural blue light, this hormone decreases. The artificial blue light that comes from electronic devices interferes with the production cycle of this hormone. It throws the sleep-wake period of the body off guard.
Blue Light Blocking glasses helps the body maintain the needed melatonin levels. It facilitates a good night’s sleep, which the body needs for optimal function. Quality sleep prevents a slew of health issues such as headaches, hypertension, and heart problems.
- It Prevents Macular Degeneration
When part of the retina is damaged, macular degeneration occurs. A person with this disease will lose their central vision. It means whether they are close or far away, they cannot see details.
Wearing blue light blocking glasses during activities that involve electronic devices will prevent blue light from reaching your retina. It mitigates vision problems.
- Prevents Digital Eye Strain
High-energy blue light scatters more easily than any other visible light. It makes it difficult for the eyes to focus. Looking at screens that emit blue light for extended periods forces the eyes to exert more effort to maintain focus. It results in digital eye-strain.
During the times you are exposed to electronic screens, the blocking glasses increase comfort. They allow the eyes to get a much-needed reprieve from visual stimuli.
The use of electronic devices is inevitable in this digital age. Yes, it may cause harm to the body, but with solutions like blue light blocking glasses, you can continue to enjoy the convenience that these devices bring.
