I'm ongoing a treatment with "Ortho-K" lenses.
It's essentially contact lenses you wear during sleep, that will gradually correct your vision by reshaping the cornea overnight.
I've been doing it for around 3 months now and my vision has improved greatly, but it was just identified that my right lense was not fully in contact with the cornea. So I'm currently waiting for the replacement lenses to heal my vision fully.
Right eye went from 4° → 0,75°
Left eye went from 3° → 0° (99% healed)

The big problem is the inbalance between the both eyes, which makes my vision extremely blurry. Which is dentrimental for a game like osu! As it's frustrating, I'm not playing until this is fixed

I tried to simulate my vision while playing and it's something like this:
(where I'm aiming is somewhat clear, but the rest of the screen is just blur)
