In today's digital age, we have become increasingly reliant on digital screens for work, socializing, and entertainment. This increased use leads to more exposure to blue light. Blue light is part of the visible light spectrum, with a short wavelength that produces high energy.
Some blue light exposure is necessary for good health, and it occurs in nature as it comes from the sun. Blue light helps to regulate our circadian rhythm and mood, but overexposure to screens can be harmful. Over time, excessive blue light exposure may also contribute to more severe issues such as macular degeneration.
How Blue Light Affects Your Sleep and Overall Health
You can feel the effects of blue light in many aspects of your health, including sleep. Blue light, especially when absorbed at night, can disrupt your circadian rhythm — the body’s natural sleep-wake cycle. This happens because blue light disrupts the production of melatonin, the hormone responsible for making you feel sleepy. As a result, you may find it harder to fall asleep or experience poor-quality sleep.
The Benefits of Blue Light-Blocking Glasses
Blue light-blocking glasses are a simple yet effective solution to the challenges posed by excessive blue light exposure. These glasses have special lenses that filter out a significant portion of blue light. This reduces its impact on your eyes and helps prevent digital eye strain.
Additionally, wearing blue light-blocking glasses, especially in the evening, can help regulate sleep patterns. They minimize blue light exposure, allowing for regular melatonin production.
For those whose work relies heavily on computers, our collection of computer glasses safeguards your eyes from those screens.
The Role of Photochromic Lenses
Eye care experts also recommend photochromic lenses for blue-light protection. These lenses automatically adjust to changing light conditions, darkening in bright environments, and returning to clear indoors.
In addition to protecting your eyes from UV rays, photochromic lenses also filter out blue light. This makes them an excellent choice for those who spend a lot of time indoors and outdoors. We share more detailed insights about the benefits of photochromic coatings here.
