'Blue‐light filtering', or 'blue‐light blocking', spectacle lenses filter ultraviolet radiation and varying portions of short‐wavelength visible light from reaching the eye. Various blue‐light filtering lenses are commercially available. Some claims exist that they can improve visual performance with...
The tunable UV/blue radiation is obtained from sum frequency generation (SFG) between the OPA output and the residual fundamental beam at 810-nm and cascaded second harmonic generation (SHG) of OPA. With a pumping energy of 75 mJ at 405 nm, the optical conversion efficiency from the pump ...
The Laser Doppler Imaging System (Moor, UK) was used to illustrate and evaluate flap perfusion. A low intensity (2mW) laser light beam (wavelength of 632.8nm) was scanned across the surface of the skin in a raster fashion by a moving mirror, thus giving a two-dimensional image of flap ...
Blue light therapy is perhaps best known for its ability to treat mild to moderate acne. By targeting acne-causing bacteria, blue light helps reduce both the frequency and severity of breakouts, while also calming inflamed skin. Studies have highlighted blue light therapy’s effectiveness, showing...
PPV, a conjugated polymer emits light in the green region of a wavelength of 540 nm and indicates a light-emitting efficiency of 0.01% when aluminum and indium tin oxide (ITO) are used as the cathode and anode, respectively. With continued studies of PPV and derivatives thereof (see WO92160...
Upregulation of retinal dopaminergic activity may be a target treatment for myopia progression. This study aimed to explore the viability of inducing changes in retinal electrical activity with short-wavelength light targeting melanopsin-expressing retin
This light, with a wavelength between 400 nm and 500 nm, is in the blue range of the visible spectrum. Blue light has been suggested to affect circadian entrainment, cause lengthened perceived duration and improve alertness [2,3,4], which is associated with the stimulating of photosensitive ...
we propose blue quantum dots with a large core and an intermediate shell featuring nonmonotonically-graded energy levels. This strategy significantly reduces surface-bulk coupling and tunes emission wavelength without compromising charge injection. Using these quantum dots, we fabricate bottom-emitting devic...

All visible light falls on a color spectrum based on the frequency of a wavelength and energy levels produced by each color. High-energy waves have short lengths and low-energy waves have long lengths. High-energy, short-length waves like ultraviolet rays are invisible to the eye but fall on...
