LOTSORB B014 High contrast powder blocks the dark red color, making it appear even redder

Dark red is the low-purity stray light reflected from red objects. High-contrast color powder absorbs/blocks the dark red light, removing the "dark interference" that dilutes the purity of red. The reflected light is now only high-purity bright red light. The human eye perceives a more saturated and brighter red, which is "more red in color".

Application of 490nm sleep-aid color powder in sleep-aid glasses

The visible light received by the human eye, which ranges from 460 to 500nm, serves as a regulator of human circadian rhythm response. Exposure to LED screens at night, particularly their blue light (460nm-500nm), significantly reduces the level of melatonin during the night and suppresses sleepiness. For instance, exposure to "Circadian Light" circadian rhythm blue light (490nm) at night can positively impact human health. Reports indicate that up to 4 hours of blue light exposure before sleep can affect the level of melatonin during the night and subjective sleep quality.

Deeply cultivating the field of functional additives and jointly building a new ecology for the eyewear industry

Anti blue light functional additive: Targeting the visual health needs of the digital age, this additive can accurately filter high-energy short wave blue light at 380-455nm, while maintaining a visible light transmittance of over 90%, in line with the technical requirements of the new national standard GB/T 381202023. Its efficient blue light blocking performance and uniform light transmission have received high attention from many lens manufacturers, and multiple companies have requested sample testing on site.

Application and principle of high contrast color powder in high contrast lenses

High contrast lenses are professional functional lenses designed to enhance visual clarity in harsh lighting environments. It is mainly used in low light, foggy, rainy, foggy, dusk, and low contrast scenes. The core optical principle lies in the intelligent management of the incident light spectrum through the built-in high contrast color powder (functional optical dye/pigment). Due to their high energy properties,

Application of blue light absorbers in anti blue light lenses

Blue light absorbers are the core of anti blue light technology, which achieve protection by selectively absorbing blue light; Anti blue light glasses are their most popular application products, and when purchasing, attention should be paid to the barrier rate, transmittance, and color cast, and scientifically choose according to their own usage scenarios. However, it should be noted that anti blue light glasses are only auxiliary tools. Reasonable use of eyes and control of electronic device usage time are the fundamental ways to protect vision.

What is the thermal Fuse?

thermal fuse or thermal cutoff is a safety device which open circuits against overheat. It detects the heat caused by the over-current due to short circuit or component breakdown. Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would. A thermal fuse must be replaced when it fails or is triggered.Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature.
