This is due to newer research revealing blue & violet visible light and certain wavelengths of infrared light (e.g., NIR, IR-A) work synergistically with UV light in contributing to oxidative stress, free radical generation, dermal cellular damage, suppressed skin healing, decreased immunity, erythema, inflammation, dryness, and several ...
Shield (Archie Comics), one of several fictional patriotic superheroes; Shield (Artemis Fowl), in the Artemis Fowl novel series, a magical ability possessed by fairies; S.H.I.E.L.D., a fictional agency in the Marvel comics universe, led by Nick Fury; Scyld Scefing (or Shield Sheafson), a legendary Danish king in the epic poem Beowulf
The shape of the shielded region would be similar to a shadow from the gravitational shield. For example, the shape of the shielded region above a disk would be conical. The height of the cone's apex above the disk would vary directly with the height of the shielding disk above the Earth. [1]
The individual autonomous flyers building up the cloud of sunshades are proposed not to reflect the sunlight but rather to be transparent lenses, deflecting the light slightly so it does not hit Earth. This minimizes the effect of solar radiation pressure on the units, requiring less effort to hold them in place at the L1 point.
Blue light is absorbed by the structural proteins, enzymes, and protein metabolites found in the lens. [9] The absorption of blue light creates yellow pigments in the lens's protein. The lens progressively darkens and turns yellow. [9] Blue light is absorbed by the lens, preventing blue light from reaching the retina at the back of the eye. [12]
Illustration of the deployed "hot" side of the James Webb Space Telescope with the sunshield protecting the main optics from sunlight. The James Webb Space Telescope (JWST) sunshield is a passive thermal control system deployed post-launch to shield the telescope and instrumentation from the light and heat of the Sun, Earth, and Moon.

a shield before the shining god. mountains and oceans I know should burn, if it fell from in front. Arvak and Alsvith up shall drag Weary the weight of the sun; But an iron cool have the kindly gods Of yore set under their yokes. In front of the sun does Svalinn stand, The shield for the shining god; Mountains and sea would be set in flames
