Hi Julie,

I had a sight test in January (a month before my diagnosis) and about 6 months later, I found I had to use my reading glasses all the time and they weren’t doing the job. I had been on Tamoxifen for a few months by then. I needed a stronger prescription, which suprised my optician, although he said that at my age (46) eyes do tend to worsen.
I had the backs of my eyes, retinas, and other stuff all tested – all clear.

My optician wasn’t able to say that the worsening eyesight was down to the Tamoxifen, because of my age.

Good luck,

Jacki xx

Thanks Lucy and Jacki,
I’m of to optician again tomorrow, so hopefully just my age too(40)
