METHOD OF ASSESSING LEVEL OF MELANOPIC DAYLIGHT DEFICIENCY Russian patent published in 2024 - IPC A61N5/06 

FIELD: medicine; functional diagnostics; somnology; public health and healthcare; occupational physiology; chronobiology.

SUBSTANCE: invention can be used to assess the level of melanopic daylight deficiency. The persons over 18 years of age wear an actimetre that records the actual level of melanopic light exposure received for at least 3 days. Then the average value of the actually received melanopic light exposure is calculated in total for every 30 minutes in the time period from 08:00 p.m. to 07:30 p.m. in microwatts per square centimetre. Next, the differences between the average values of the actual melanopic light exposure and the recommended values are determined. The average value of neighboring differences is found. The sum of all average values of neighboring differences that have a negative value is calculated. If the sum of all differences having a negative value is higher than minus 275 microwatts per square centimetre, then the level of melanopic daylight deficiency is assessed as low. If the sum of all differences having a negative value is from minus 275 to minus 550 microwatts per square centimetre, then the level of melanopic daylight deficiency is assessed as average. If the sum of all differences having a negative value is below minus 550 microwatts per square centimetre, then the level of melanopic daylight deficiency is assessed as high.

EFFECT: method provides an individual assessment of the level of melanopic daylight deficiency based on actimetry, which records the actual level of melanopic light exposure obtained.
