The myopic shift of early cataract can easily precede visible brunescence or
haze. That's my guess.

What are the possibilities?

Keratoconus - there is no big change in astigmatism

Posterior staphyloma - the fundus wasn't examined but PS doesn't develop
suddenly at age 49

Diabetes - both eyes didn't change

Nuclear Sclerosis - easily explains 2D of myopic shift, and it explains the
reduced corrected VA.

Many 50-year-olds with asymmetric cataracts have a history of trauma to the
affected eye.
