The seeing eye got worse 😏

Hi everyone, I’m blind in my left eye and wear a scleral shell. Last week, while taking it out, I accidentally scratched my cornea. I had a follow-up appointment today and thankfully it has healed well. Since I was already there, I also had my seeing eye checked because I felt my glasses might no longer be strong enough. I already know that I have early-stage cataracts in that eye, but today I found out that my vision has dropped to only 60%. I’m honestly feeling quite down about it, and I’m worried that I might eventually no longer be allowed to drive. Has anyone here gone through something similar?
