Sentence examples for visual brightness from inspiring English sources

The indication for phaco-AIT consisted of a visually significant cataract with at least 0.4 logMAR (20/50 Snellen) visual brightness acuity testing and the need to lower IOP or the number of glaucoma medications.

They record subject colour values as gray tones largely corresponding to the visual brightness of the colours.

Design and fabrication of optical films to increase visual brightness of OLED (Organic Light-Emitting Diode) lighting units are presented in this paper.

A long-period variable may change a hundredfold in visual brightness, but the variation in energy output is much smaller because at the low temperature of such a star most energy is released at infrared wavelengths rather than as light.

The range in visual brightness during a pulsation can be 100-fold, but the range in total energy output is much less, because at very low stellar temperatures (1,500 3,000 K) most of the energy is radiated in the infrared as heat rather than as light.

In addition, the visual brightness of LEDs can be readily controlled by tuning the gate voltages of the OFETs.

The results of investigations of visual light curves, brightness outburst activity and photometrical evolution of some comets are presented.

The most common type shows a distinctive "plateau" in the light curve shortly after peak brightness where the visual luminosity stays relatively constant for several months before the decline resumes.

A field study was performed to examine the effects of correlated color temperature (CCT) and lumen output of fluorescent lighting on office occupants' visual comfort, brightness perception, satisfaction, and self-reported productivity.

Successive columns give the name of the star, its brightness expressed in visual magnitude and spectral type (see below Classification of spectral types), the distance from Earth in light-years (a light-year is the distance that light waves travel in one Earth year: 9.46 trillion km, or 5.88 trillion miles), and the visual luminosity in terms of that of the Sun.

Similarly, a significant two-way interaction of the factors "light condition" and "session" was observed for visual glare and brightness (F6,17 = 2.8, p = 0.01; Fig. 4, bottom panel), with a significant increase during light at 6500K in comparison to 3000K and 2500K.
