What is blue light and how does it affect our eyes?
Blue light is a type of high-energy visible (HEV) light with a shorter wavelength, typically in the range of 400-450 nanometers. It is emitted by digital devices such as smartphones, computers, televisions, and other electronic screens. Prolonged exposure to blue light has been linked to digital eye strain, which can cause symptoms such as dry eyes, headaches, and blurred vision. Furthermore, some studies suggest that blue light exposure may also contribute to the development of macular degeneration and other eye problems over time.
The effects of blue light on our eyes can be explained by the way it interacts with the eye’s anatomy. When blue light enters the eye, it is not fully absorbed by the cornea and lens, but rather passes through to the retina, where it can cause damage to the sensitive photoreceptor cells. This can lead to a range of problems, from mild discomfort to serious vision loss. To mitigate these effects, it is essential to take steps to block or filter out blue light, especially in the evening or when watching TV for extended periods. This can be achieved through the use of blue light filtering glasses, screen protectors, or software that adjusts the color temperature of the screen.
How can I block blue light from my TV?
There are several ways to block blue light from your TV, depending on the type of TV you have and your personal preferences.
