Three years ago at age 25 I booked an eye exam due after getting some new floaters. After imaging my eye doc came in and asked if I was comfortable driving while dilated, because he would be dilating and numbing my eyes before sending me off to the retina specialist for an urgent exam. The ophthalmologist immediately diagnosed me with lattice degeneration and saw a horseshoe tear. That same afternoon he sat me in a chair and used a laser to create a barrier of scar tissue around the tear to prevent it from progressing. Three years later I have had two rounds of prophylactic treatment of those weak spots in each eye. I most likely will never experience a retinal detachment, but annual dilated eye exams are in my future.
I don't even have very bad myopia (-2.75/-3.25), but I kick myself for not spending as much time outside during my childhood as some of my friends did.
