You can turn fully invisible at will, photons pass right through you until you choose for them not to, but you also cannot see while invisible

At any time, you can camouflage yourself with your surroundings. It takes 10 seconds to complete the camouflage, and in that time, or if you move, or if your background changes, you are visible. You can see. You can decamouflage at will too, which also takes 10 seconds.
In both cases, it is just your body which is affected, not anything you are wearing. Piercings or medical stick ons count as part of your body for these purposes.
I choose 1 and either learn echolocation, or get a fancy implant that does it for me.
Although if 1 is instantaneous and you have perfect control of the power, you could probably avoid others seeing you by flickering really fast. I bet there’s an optimal pulse width and frequency where you would be effectively invisible to people while still being able to see enough. A high speed camera would still catch you though.
Do some training so that you could flicker at exactly 60 frames a second, and most cameras, assuming that you caught the right 60th of a second, would not even see you.
You also might be able to time with the saccadic rhythm of the eyes and make yourself invisible to a single viewer while still retaining your vision thanks to persistence of vision.
And, assuming you knew you had to walk in a straight line or something, you could just go invisible, walk straight forward to your destination, and then turn visible again.
