I am early 30s, had glasses since being a young child and contact lenses since about age 10. Prescription about -6 ish.
Past fortnight I've noticed a deterioration in how well I could see. Right eye felt blurry and I kept cleaning and replacing contact lenses. Having to squint in glasses. Vision changing (or that was my perception throughout the day).
I had an eye test today, my eyes have improved by +0.5 in each eye. This appears to have been a concern but no one would say why, just that it was a worry and I have to return in two weeks.
Why could this be?
