Various LED light-emitting display devices, such as TVs, computers, and mobile phones, have enhanced image quality, making visuals brighter and more vibrant. However, this advancement has also increased the intensity of blue light emitted by LED backlights. With the growing prevalence of these devices in everyday life, exposure to blue light has risen significantly. For most people, limiting prolonged exposure to blue light is the most effective way to minimize its harmful effects, and wearing anti-blue light glasses offers a practical solution.
Anti-blue light lenses are designed to reduce eye irritation caused by blue light. These specialized lenses effectively block ultraviolet rays and radiation while filtering out blue light, making them ideal for individuals who frequently use TVs, computers, or mobile devices.
Damage to Eyes: Harmful blue light carries high energy that can penetrate the eye’s lens and reach the retina. This can lead to the atrophy and even death of retinal pigment epithelial cells, resulting in diminished or complete loss of vision, which is irreversible. Additionally, prolonged exposure to blue light can contribute to maculopathy.
Visual Fatigue: Due to its shorter wavelength, blue light focuses slightly in front of the retina rather than directly on it. This forces the eye to remain under constant tension to maintain clear vision, leading to eye strain. Prolonged visual fatigue can cause issues such as worsening myopia, double vision, difficulty in focusing while reading, and reduced productivity, negatively impacting learning and work efficiency.
Poor Sleep Quality: Blue light suppresses melatonin production, a hormone critical for sleep and regulating circadian rhythms. This explains why using phones or tablets before bedtime can disrupt sleep, causing difficulty falling asleep and poor overall sleep quality.
Anti-blue light glasses can effectively reduce the sustained damage of blue light to the eyes. Through the comparative detection of portable spectrum analyzer, the intensity of blue light emitted by the mobile phone screen is effectively inhibited after the use of anti-blue light glasses, reducing the harmful blue light to the eyes. They mainly reflect the harmful blue light by coating the surface of the lens, or absorb the harmful blue light by adding anti-blue light factor into the substrate of the lens, so as to achieve the barrier of harmful blue light and protect the eyes.
