A large number of students and office workers wear thick glasses, mostly due to prolonged exposure to electronic screens. For this reason, a suitable pair of radiation-protective lenses is indispensable. But what is the working principle behind these glasses?
Radiation-protective glasses are designed to shield the eyes from damage caused by excessive ultraviolet rays and other forms of radiation. The lenses are made of special glass that can reflect or absorb radiation while allowing a certain amount of visible light to pass through. They are coated with a shiny metallic film of chromium, nickel, mercury, silver, or other metals to reflect radiation. Blue lenses absorb infrared rays; yellow-green lenses absorb both ultraviolet and infrared rays; and lead-containing clear lenses absorb X-rays and gamma rays. Take welding glasses for example, they have relatively low light transmittance requirements, so their lenses are mostly dark-colored. Laser-protective glasses, as the name implies, are engineered to block laser radiation, which places high demands on the lenses. Factors such as light source compatibility, attenuation rate, light response time, optical density, and light transmission effect all matter. Different nanometer (nm) lasers require lenses with corresponding wavelength bands.
Features of Radiation-Protective Glasses
Flat lenses, no side effects on vision Crafted using advanced vacuum ion plating technology, these lenses can block 100% of electromagnetic radiation.
Radiation-resistant material composition
The lenses contain radiation-blocking substances that absorb low-frequency microwave radiation, eliminating potential eye discomfort caused by electromagnetic waves, such as eye fatigue, headache, soreness, and dryness.
Selective light transmission and absorption
The lenses exhibit differential penetration and absorption capabilities for various light rays, offering anti-reflective and glare-reducing properties. Users will notice significantly clearer and more natural vision when wearing them.
Ideal for specific user groups
Especially suitable for computer professionals, TV viewers, and video game players, these glasses effectively block harmful light from damaging the eyes, ensuring long-term visual health.
How to Identify Authentic Radiation-Protective Glasses
Check the coating layer Radiation-protective lenses are coated with a colored anti-radiation film, which can be blue, green, golden, or other hues. Blue-green coatings are standard anti-radiation layers, with a radiation-blocking rate of approximately 50% as verified by national testing standards. High-performance golden coatings incorporate special silver oxide components, achieving a radiation-blocking rate of up to 90% according to national certification.
Test by wearing them while using a computer
Put on the glasses and experience the difference when looking at a computer screen. Without radiation-protective glasses, the display may appear harsh on the eyes and slightly flickering. In contrast, wearing authentic radiation-protective glasses will deliver noticeably clearer and more natural visual comfort.
Prolonged use of mobile phones, computers, and similar electronic devices often leads to eye strain and dryness, making radiation-protective glasses a necessity for many people. However, we would like to offer a friendly reminder: always purchase these glasses from authorized physical stores or Eye Clinics after getting a professional eye exam and prescription.
