Well if you have the right tools, you can cut out the shape of your visor from a sheet of plastic (roughly 1/8 inch) as then for there you can super heat it by 225 Fahrenheit to make it malleable to whatever shape you need it to be. At a Tap store, they sell unused pieces which will cost $1.
From there, you can apply tint film on it.
Another method it to create a wire frame to the visor shape and apply a tint film over it. Costs are OK depending where you buy the materials from.
When in doubt, just take the next small step.
With that next step take a deep breath. It calms the mind.
When the mind is calm you realize the best is still yet to come.
