Offering advice on protection from macular degeneration goes outside the scope of this forum (and software), unfortunately.
One thing you might want to look at is our resource on spectral measurements of different light sources and interventions (like physical filters or software settings). https://fluxometer.com/rainbow/ So you can see that most LED backlit smartphones and screens don't give off much ultraviolet light, but they do have a spike in the blue range. You can do some research there, and hopefully your ophthalmologist should be able to help you find an intervention that would be best for your needs and your eyes.
