. . .it involves a cellular function of the endothelial cells which make up the blood vessel walls -- when chronically or traumatically exposed to stress hormones such as cortisol or adrenaline -- they become dysfunctional. This dysfunction leads to the walls of the endothelial cells constricting.
This reduces blood flow to crucial areas of the brain, such as the neurons that feed directly into the retina. Depriving neurons in the retina of oxygen and glucose means they'll be functionally impaired.
Data points to a type of perfect storm between genetics, stress-coping and vascular dysfunction that can cause a radical degree of vision loss. However, in a general sense, the biological effects surrounding psychological issues should be taken more seriously in order to better understand (and treat) the sometimes ambigious biological connection between the mind and the body.
Additionally, it's this kind of data that will allow Magic Leap’s new patented use of a “light analyzer configured to determine a polarization angle rotation of the reflected light from the eye of the user” to detect glucose levels based partly on the reflected light.
These glasses would then look at previous glucose readings and “provide an alert to the user or clinician in response to comparing the contemporaneous glucose level with the historical glucose level.”
And these Lightwear "smart glasses" wouldn’t just monitor glucose levels: the device could track physical changes in the user’s body, including “body temperature, skin temperature, heart rate, respiration rate, level of sweating” and then inform the wearer or a medical professional when “at least one parameter falls outside a range.” The eyewear would also be capable of tracking activities such as: eating, taking meds, exercising, or a combination thereof.
