'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...
Multiple-wavelength coverage in a single protective eyewear filter is a common requirement. Having one filter to cover all the laser wavelengths used in an environment is better than having multiple pieces of protective eyewear equipment because this helps to avoid the possibility of the wrong eyewear...
visual sensation- the perceptual experience of seeing; "the runners emerged from the trees into his clear vision"; "he had a visual sensation of intense light" vision aesthesis,esthesis,sensation,sense datum,sense experience,sense impression- an unelaborated elementary awareness of stimulation; "a ...
Effect of visual stimulation with 10-ms 620-nm light pulses at 0.6 Hz on EEG power spectrum. The profile of spectral power over 24 h was compared between the baseline day and the next day during which the visual stimulation was performed. The profile of spectral power in mice stimulated wit...
an important role in non-visual effects of light and have a peak sensitivity in the shorter wavelength part of the visible spectrum. Such photoreceptors are known as intrinsically-photosensitive retinal ganglion cells (ipRGCs), and their intrinsic photosensitivity is based on the pho...
One way to reveal the existence of the macular pigment is by intermittent observation of a uniform field of short-wavelength light. One sees a shaded spot, Maxwell’s spot, named for its discoverer James Clerk Maxwell. Another method is to look at a uniform white field of light through a ...
The attraction is eliminated by filtering the orange and red bands from the skin color spectrum and by introducing mutations targeting specific long-wavelength opsins or CO2 detection. Collectively, our results show that odor is critical for mosquitoes' wavelength preferences and that the mosquito ...
Behavioral studies regarding optomotor response have shown a dependence on light wavelength, demonstrating that zebrafish larvae produce an optomotor response to red or green motion but not to the shorter wavelengths [9]. Phototaxis assays, on the other hand, have shown that larvae, when faced wi...
However, artificial nighttime lighting can interfere with insect ecology in a wide variety of ways8, and potential solutions for one problem may be inappropriate for others; for example, narrow-band long-wavelength lighting may reduce interference with bioluminescent signals, such as those of some ...
The visual attenuation composition can be formulated to impart a shade of green to the substrate when applied. Green is a color, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of about 520-570 nanometers. Pigment and dyes, alone or in com...
