The Energy of a Light:Light is an electromagnetic wave associated with chargeless or massless particles called photons. Each photon of a particular light of a wavelength has a fixed amount of energy. The energy of a photon depending on the wavelength of the light ca...
Low-intensity, long-wavelength red light slows the progression of myopia in children: an Eastern China–based cohort. Ophthalmic Physiol Opt. 2022;42(2):335-344. doi:10.1111/opo.12939 PubMedGoogle ScholarCrossref 39. Chen H, Wang W, Liao Y, et al. Low-intensity red...
When a wave comes, you go up, then down until another wave lifts you back up. A "Wavelength" is the amount of time that passes between these two waves. Light has a wavelength as well. What's more...Light has different wavelengths, just like waves in the ocean (on g...
Pure red light of, say, 650nm wavelength is not common in lighting. There is a substantial amount of yellow and orange being produced. So brightening the light brightens wavelengths that can damage night vision. The ideal light for night use would have zero emission below about 600nm and pre...

You are looking at a star chart (which no one seems to use anymore ) Walking around? It’s amazing how bright it is out when you are dark adapted. However “dark” it is. TBH, once you are dark adapted, a light of any kind brings your only vision into that small tunnel of light...

As an alternative to increasing bright light exposure, we propose to deliver light on the retina directly at a much shorter duration of exposure but repeatedly for myopia control. We intend to use a device that emits red light at 650 nm in wavelength based on the fact that this was already...
PTT efficiency is dependent on the NIR absorption wavelength and coefficient of the photothermal agent and the power of the excitation light113. In PDT, the photoactivated photosensitizer generates a chain of photochemical reactions to produce reactive oxygen species (ROS) leading to cell death. To ...
