Database of causes, symptoms and solutions

Great idea, for starters I think google spreadsheet is enough. I did this for dry eye people from dry facebook group: https://docs.google.com/spreadsheets/d/1xkhq_wKNaj3x2BZJamS1MLtQTWpOsZaHF3Vvlzw58tg/edit?resourcekey#gid=1930799635

Anwers come from survey in google forms

mazury That is such a cool spreadsheet. I mean both the contents and the way you've laid it out.

GregAtkinson Thanks. It should be pinned so that groups newcomers can easily access it, but it's always up to moderators. It would be great if we had something like this here pinned. Could be google form survey first (or any survey provider) or answers steraight away to spreadsheet, although that would demand a certain level of trust that nobody edits others answers.

Solving all problems (if eyes hurt)

Don't buy iPhones 11/12/13/14/15
Don't buy Samsung phones
Don't buy Microsoft Surface
Don't buy a Google Pixel
Don't take OLED | Amoled
Walk outside more often

AlanSmith well iPhones definitely are the worst for me but the Xiaomi 13T even being amoled has been night and day better.not perfect but I can at least start using a screen again. Haven't found anything more comfortable yet

AlanSmith

Why do your eyes hurt at low brightness on your phone? - The lower the brightness, the less the PWM is too. If the PWM is low, the eyes grow tired more. Take the Honor 90 ($450) AMOLED 3840Hz. Let's check how safe the smartphone is for the eyes.

Using is Radex LUPIN (120Hz screen refresh rate)

100% brightness, PWM 2500Hz (pulsations 4.78%)

50% brightness, PWM 1500Hz (pulsations 7.67%)

0% brightness, PWM 882Hz (pulsations 13.6%)

Marketers cheated! PWM 3840Hz not there?

Answer -> Only in 60Hz screen refresh rate.

jordan

AlanSmith so when does the 3840hz go in affect?

AlanSmith

jordan PWM is 3840Hz in 60Hz screen refresh rate. When 120Hz is turned on, the PWM is half as low (Even PWM 2500Hz is still better than any Samsung and Apple phone). Honor 90 is the best phone of 2023 for people with sensitive eyes.

jordan

AlanSmith ohhh I see. Wonder how it is compared to the honor 100. Does that also only offer 3840hz in 60hz? My 13T is 2941hz with120hz refresh rate

AlanSmith

jordan No, Honor 100 on OLED. On Honor 90 GT OLED too. (Update)

jordan

AlanSmith do you know if those will run 3840hz at high refresh rate? 60hz refresh rate bothers my Brain

AlanSmith

jordan Just buy the Honor 90 from Amazon (and return if you don't like it).

AlanSmith

jordan Redmi Note 11T Pro (LCD) for $300 is also safe for your eyes.

GregAtkinson Thanks for putting this together! I like that your survey is short enough that sensitive people can complete it quickly and hopefully it will help to identify any usable devices.

I also encourage anyone who is able to do so to please complete this longer symptom survey https://www.flickersense.org/survey-of-led-sensitivity which is still accepting responses - previously posted in this discussion. The full dataset and an initial analysis are posted publicly. I’m hopeful that we can soon get medical and public health research started (I’m working with others to try to get it to happen). Having as comprehensive an understanding as possible of the breadth and variability/commonality of our symptoms will be helpful to researchers new to LED/screen injury. Thank you everyone who is willing to help!
