RE: Sneaky Ground!
Also, get some flights in around noonish (or sun-high as possible)
That way your shadow is as close to right under u as you can get it, then use the shadow to judge distance.
Alternatively...have a spotter with you. pick spots on the runway (threshold, target landing zone, treeline) and have them call them out as you pass over them.
You will only need to do these kinds of things a few times before your brain will take over and get it right without you having to think about it.
I right-handed left-eye dominant and my right eye is very light sensative, so i fly one-eyed alot, even with a hat and glasses on. It was hard for me at first because we dont even have a threshold. We have almost limitless runway as far as actually landing is concerned.
