Let's Be Clear About Blue
1. Ultraviolet radiation and high energy visible blue light are high energy electromagnetic waves that when absorbed by ocular tissue can result in:
2. To prevent melatonin suppression and subsequent sleep deprivation it is recommended we stop exposing our eye to 460 to 490 nm with this period before bedtime:
3. According to Prevent Blindness America, HEV blue light from Digital devices:
4. Around the world, there are varying standard definitions of the visible light wavelength range on has visible light beginning at 400nm, but this course uses the definition that starts visible light at:
5. The mechanism for blue light induced molecular damage to ocular tissue is _______ in nature.
6. Even on a rainy day ___% of UVR still reaches our eyes.
7. Young eyes under 20 years of age transmit up to ____% or more of blue light to the retina.
8. UVR exposure is greatest near the equator and:
9. Our biological master clock that sets our 25 hour sleep/wake cycle is called:
10. UVR absorption can induce damage to the crystalline lens and contribute to the development of _________.
11. Because HEV blue light is visible light it transmits to the retina making it potential ocular hazard for:
12. This by-product of the visual cycle is a potent photosensitizer that can amplify damage to retinal pigment epithelium cells.
13. When these intrinsically photosensitive retina ganglion cells (ipRGCs) are exposed to beneficial blue wavelengths, they set our circadian clock rhythms to the light/dark cycle but also modulate:
14. The debris that forms in the RPE cells of the retina is called Lipofuscin which acts as a ___________.
15. Photosensitizers increase the sensitivity of the retina to _________.
16. When our eyes are exposed to the longer blue wavelengths too close to bedtime our sleep can be disrupted due to the suppression of this hormone:
17. Mitsui UV+420cut™ is an in-mass lens technology that cuts HEV blue light from:
18. Our circadian rhythm refers to the syncing of our bodies and physiological process to a ___hour cycle including our sleep cycle.
19. Mitsui UV+420cut™ uses a ____-____ optical filter to create a clear lens as opposed to other blue blocking in-mass lens technologies that appear yellow.
20. When we block blue the eye sees the complimentary color in older blue blocking lens technologies. What is the complimentary color of blue?
