“Its levels oscillate daily, peaking one hour into sleep and ebbing two hours after waking. Non-visual photoreceptors in the eyes regulate circadian clocks "This blue light sensor in our retina connects to our brain to reset our clock or to tell when melatonin should rise or fall."”

“In STEP 1, once-weekly semaglutide plus lifestyle support produced an average weight reduction of 14.9% over 68 weeks, compared with 2.4% with placebo, establishing strong efficacy for selected adults with overweight or obesity.”

“Impaired blood flow to the optic nerve in the eye is one factor that plays a role in causing glaucoma. Green leafy vegetables are high in nitrates, which form nitric oxide and is beneficial for blood flow to many tissues including the eye.”

“The highest concentrations of mitochondria in the body are found in the rods and cones of the eyes, where they support multiple aspects of vision. Findings from a new study indicate that viewing a red light restores mitochondrial function in the eyes of older adults.”

“Nearsightedness (myopia) rates are rising, and this might be due to how much we’re looking at screens that are very close to our eyes. Close viewing may be particularly detrimental for children, but the good news is that spending time outside seems to help.”

“Red light has the longest wavelengths on the visible spectrum, and previous research indicates that exposure to red light restores mitochondrial function in the eyes of older adults. The current study involved 20 adults between the ages of 34 and 70 years who had no eye disease.”

“Researchers analyzed data from two separate groups of U.S. adults: about 7,800 people who reported their dietary intake of lutein and zeaxanthin through food surveys, and about 7,300 people whose blood levels of these nutrients were measured in lab tests.”

“Melanopsin is specialized for communicating circadian information. To learn more how the important role early bright light exposure plays in circadian training, check out my first podcast episode with Dr. Satchin Panda, who discovered melanopsin.”

“The thought-controlled keypad would allow a person with paralysis or ALS to run an electronic wheelchair and use a computer or tablet with less fatigue of operation that ordinarily comes from using the existing methods that use eye-tracking or head movement tracking devices.”
