I'm sorry about the conflicting information you've received about this J.

I've had a quick look on our website and can see that 'eye problems such as blurred vision, cataracts or irritation'  is listed under rare side effects so this may be what the optician is referring to but it may be worth giving our cancer nurses a call about this on 0808 800 4040 (phone lines open Monday - Friday between 9a.m - 5p.m) to find out more.

Hopefully some of our members who are taking Letrozole will pop by soon to let you know if they've had this problem as well.

All the best,

Hi I've been on Letrozole since February 2020 and had an eye test a couple of months ago she said I have the start of cataracts and would now see me yearly to monitor it I told her I was on Letrozole when she asked if my medical history was the same. But I googled Letrozole and eye problems after I got home and it says cataracts can be a rare side effect
