I’ve been (mostly!) enjoying using the Mudita Kompakt during the day, but once evening arrives I have difficulty using it - even in dark mode at the lowest brightness setting - as my eyes are extremely light sensitive.
To address this, I ordered red light gel filter sheets (designed to filter out blue and green light) and prototyped a simple screen filter by cutting the gel to the same size as the official screen protector.
I have to say, the results are amazing. The phone is much easier on the eyes, especially in the early morning and evening hours (though I still try to minimize phone use during those times).
My next step is to custom-cut a sheet so it fits just under the lip of the case and can be held securely in place without adhesive.
