I'm sorry to hear about your diagnosis, but glad you've found our community. It's good that your doctor thinks you are at a very early stage. I'll try to answer some of your questions from my own personal experience and knowledge, but I'm not a medical professional, just a fellow sufferer. Some people progress very slowly and you might be one of them. Some people can progress faster, and this is why we try to instigate some lifestyle changes to mitigate this. I've had dry amd for about seven years and don't have any real problems yet. I take the AREDS2 formula supplements and I think they help me, although we never really know.
Wet amd is generally considered more serious because it can develop and progress quickly. An Amsler Grid is recommended to check your sight between specialist appointments. If you see any changes, you should contact your doctor. This is to pick up quickly if your vision changes from dry to wet. https://maculardegeneration.net/vision-tests
As far as blue light is concerned, the science appears to be a little conflicted, but I'm attaching a link to an Editorial article on our sight on this topic. https://maculardegeneration.net/clinical/uv-blue-light
I use a dark mode on my phone to reduce blue light and I'm attaching a link to an article on our site about this. https://maculardegeneration.net/living/dark-mode-night-shift
I hope this information helps you. When you've had a chance to digest it, please get back to us with any more questions. Best wishes to you, Wendy, Advocate.
