So stop flying if you find using your iPad a such a problem. Or fly at night, places like BangGood have strips of LEDs you can dress your quadcopter in.Or buy some goggles. They've already been mentioned twice in this thread, why not try them instead of complaining about Nature and the Sun. We all use Samsungs, iPads Nexus and some DJI very expensive monitor, but very few seem to be complaining about them. Yes, they can be hard to see when in direct sunlight. So stand in the shade or take a large umbrella to stand under, or fly from your bedroom window, remove the culprit, the Sun. The same one which has been there well before quadcopters were thought of. (I think)

There are options, wear a dark shirt, a large brimmed hat, find a friendly tree or train someone to follow you around with a large sheet of timber. Hey here's an idea, only fly on overcast days. Move to the UK, they're always complaining about the weather. They only know it's summer because the rain gets warmer. It's OK, don't get upset about a racist remark, I'm an ex Pom.
Honestly it's a hobby, and hobbies are a matter of choice, you chose to get into it and sadly the sun is part and parcel of the outdoors. Have you tried goggles? the one I just purchased gives a first class picture, it's like watching everything on a massive TV. If you suffer from bad eyesight you can fit an old pair of glasses inside and everything is suddenly pin sharp. There's a video on YouTube which shows how it's done, a very simply 10 or 15 minute job. Give them a try they aren't expensive, I paid just $9.99 for mine, you can even buy cardboard kits you can put your iPhone in. Technology is great, if you're willing to experiment. Rather than just complaining about the light, I'm positive you can find a better way.
