There is a problem that you should pay attention to is that anti-fall and good-looking are basically two extremes. Good-looking may not be anti-fall, and anti-fall may not be good-looking. If you have both of them, it is a basically impossible task for manufacturers.
My suggestion is to use the four corners to prevent fall. The kind of transparent and simple can let others see your body color in the sky, but the disadvantage of this transparency is that it is easy to yellow.
