I can read the the things I want to read on the 830 no problem, especially now. My watch will put up a full screen of 3 point text (for no reason) that is impossible for me to read with no glasses. Like when I'm swimming, it's all just lost on me. The 830 does this too, do the developers even ride bikes, ever? Even if I had my readers on, I sincerely doubt I would want to read a wall of text while I was riding my bike, and I surely don't want to stop to do it. I tried locking the screen on the 830, but it still does this. Locking just means I can't do it, not the developers.
When I still had cataracts, I could read my 830 okay during the day. But at night I needed glasses. Now I need sunglasses so I'm not in pain from all the light, so I get cheap bifocal safety glasses.
