In today's digital era, we are surrounded by screens, from smartphones and tablets to computers and televisions. While these devices provide convenience and entertainment, they also emit blue light, which is next to ultraviolet (UV) rays on the wavelength spectrum. Without a doubt, UV rays can harm the eye, but can blue light harm the eye as well? And if so, can we just block the blue light from entering the eye? We’ve all heard of blue light filters before, but do they actually work? The short answer is… not necessarily. In this blog post, we will explore the concept of blue light filters, how blue light can affect you, and practical solutions to everyday issues that arise.

Understanding Blue Light:

Blue light is a high-energy light within the visible light spectrum. It is emitted by the sun, but it is also produced by various artificial light sources, including digital screens. While blue light is essential for regulating our sleep-wake cycle and boosting mood and alertness during the day, can overexposure to blue light have negative effects on our eyes and overall well-being?

The Role of Blue Light Filters:

Blue light filters, also known as blue light blocking lenses or coatings, are designed to reduce the amount of blue light that reaches your eyes. These filters work by selectively blocking or absorbing blue light while allowing other beneficial wavelengths to pass through. Blue light filter glasses have lenses that are specifically designed to block or absorb a significant portion of blue light. These glasses can be worn as prescription glasses, non-prescription glasses, or as specialized computer glasses for extended screen use.
