UV radiation is arisk for the eyes. Since early 2018, all clear ZEISS plastic eyeglass lenses have come standard withZEISS UVProtect technology. Just like a good pair of sunglasses, it delivers protection against UV radiation up to 400 nm. That’s because UV rays are all around us, they’...
Check UV Index!Everyday. sun rays (UVA/UVB) generate free radicals in the skin. One of the main factors behind the formation of dark spots, which make...
Summary of UV in cancer treatment. UV light can be generated by X-rays and near-infrared light through the excitation of scintillating nanoparticles (SCNPs) and upconversion nanoparticles (UCNPs), respectively, thereby circumventing their poor penetration drawbacks. In addition to its inherent ability...
At the same time, we are working on further enhancing the disinfection performance. We are developing a safe and efficient disinfection technology that minimizes the waste of ultraviolet rays emitted from UV-LED, aiming to establish elemental technologies that can be applied to a wider range of pr...
rays in sunlight than UVB rays. The UVA rays penetrate more deeply into the skin and play a greater role in premature skin aging, and partly in skin cancer formation. The UVB rays are responsible for producing sunburn. In addition, UVB rays play the greatest role in causing skin cancers, ...
Physical UV Defense SPF 30 is a sunscreen for sensitive skin that provides all day hydration and broad spectrum protection against UVA and UVB rays.
haze can be really difficult to deal with. When photographing distant landscapes, haze is a very common occurrence. It can happen due to humidity, pollution, dust and smoke presence in the air, which all reflect sun rays back into the camera, resulting in reduced contrast. It can happen any...

Apply the sensor to a nail using an adhesive, and you can reapply it using additional adhesives that come packaged in the box. Placing it on your thumbnail exposes the UV Sense to optimal sunlight, and the sensor is activated by UVA and UVB rays. Along with your UV report, you’ll also...
UV rays have enough energy to initiate scission reactions in polymer chains [1]. Lignin and carbohydrates components of wood are UV sensitive [2]. The resulting effect in wood leads to its discoloration and a change in its chemical and mechanical properties. The change in wood color is the ...
