Introduction

TR90 glasses are a popular choice for eyewear, known for their lightweight, flexible, and resilient nature. This article evaluates the effectiveness of TR90 glasses in blocking harmful blue light, which is crucial for reducing digital eye strain and maintaining eye health in the digital age.

Understanding TR90 Material

TR90 is a thermoplastic developed in Switzerland, praised for its exceptional durability and comfort. Glasses made from TR90 weigh approximately 20% less than those made from acetate or plastic, making them ideal for prolonged wear.

Blue Light and Its Effects

Blue light is part of the visible light spectrum, with wavelengths between 380 nm and 500 nm. Prolonged exposure to blue light, particularly from screens, can lead to digital eye strain, disrupted sleep patterns, and potential eye damage.

Studies indicate that blue light exposure can disrupt melatonin production, leading to sleep disturbances. Moreover, higher energy wavelengths of blue light (around 450 nm) are thought to pose risk to retinal health over time.

Effectiveness of TR90 Glasses for Blue Light

TR90 itself does not inherently block blue light; however, lenses fitted into TR90 frames can be specially treated or coated to filter out a significant portion of blue light. Studies show that lenses with blue light filtering capabilities can block about 20% to 60% of blue light, depending on the quality and type of lens coating used.

EASON OPTICS Company Solutions

EASON OPTICS offers a range of TR90 eyewear solutions, incorporating advanced blue light filtering technology. Their lenses are engineered to block up to 50% of harmful blue light, offering both prescription and non-prescription options.

Conclusion

TR90 glasses, when equipped with appropriate blue light filtering lenses, provide an effective means of reducing exposure to harmful blue light, thus mitigating digital eye strain and promoting better sleep hygiene. They are an excellent choice for individuals seeking both comfort and eye protection in their eyewear.
