Went for a free eye test at Tesco in Slough today cos my 20 year old frames
are broken and I need a new pair. Surprisingly my prescription hasn't
changed much more than a jot in nearly 35 years. Back in 1977 I was minus
1.75 dioptres in both eyes (short sighted) with a touch of astigmatism. The
astigmatism moved around a bit over the various tests over the years but
the basic sphere correction has stayed the same. My old specs work just as
well as they ever did. I thought eyes might get worse over time but
apparently not. I'm still minus 1.75 in both eyes and can still read the
smallest print on the charts despite the inevitable eye lense hardening
over the years.

Do other people find the same or do eyes generally get worse over time?

I take it from that you're getting towards mid 50s. With that amount of short
sight you probably don't use your specs for reading. I'm about -4 and -4
astigmatism. one eye hasn't changed much since 1967, but the other has
reduced short sight in the last few years.

Reading is still fine with no specs but bifocals are deployed normally, and
an intermediate pair for comfortable computing.

I no longer can focus half way up my nose as I could 30 years ago, I now have
to use a magnifying glass for anything closer than 70mm.
