The Oura ring designers made a huge mistake by introducing little green lights into the gen 3 and 4 rings.
The most fundamental, non-negotiable rule of design is NO LITTLE GREEN LIGHTS IN THE BEDROOM.
While the lights introduce features such as blood oxygen sensing and activity-induced heart rate tracking, you can toggle these off in the apps and the little green lights reduce their activity but do NOT turn off.
Putting the ring in airplane mode does NOT stop the little green lights.
The little green lights can light up a blacked-out bedroom like a flashlight!
Green and blue light are anti-sleep.
The purpose of tracking your sleep is to gain insights that will improve it.
If your tracking involves lighting your room up with anti-sleep blue or green light you are shooting yourself in the foot from the start.
I thought I lost my gen 2 ring and opened up a backup gen 3 ring I had bought two years ago but never used and quickly saw how intolerable these little green lights are. Thankfully I found my gen 2 ring the next morning.
Oura MUST introduce the ability to COMPLETELY DISABLE the little green lights within the app.
You should be able to toggle on automatic disabling that lasts for 11 hours starting 2 hours before your scheduled bedtime, and you should be able to manually toggle on and off the little green lights at will.
Until that happens, DO NOT buy a gen 4 oura ring. Get a used gen 1 or gen 2 ring.
Ebay is a good place to look for a used ring your size.
