IPAD GLARE ON SCREEN

It’s a problem with any backlit LED display. In my experience, an anti-glare screen protector can help a little bit, but not much. Using it in some form of shade is the another option - there are collapsible/foldable sun shades for iPads on Amazon. But they look like they also could be annoying to carry around.

There are some anti-glare screen protectors. You can search on amazon.

Unfortunately, the ipad was never really designed for reading books on a beach for example. All backlit screens don’t do well in sunlight.
