Tamoxifen and eyes

I have been told that Tamoxifen can cause cataracts or make existing ones worse. I am 45 and have some cataracts that I was born with so had these checked before I started Tamoxifen. I will be monitored every year unless I need it. I am finding that I get blurry vision more often, I am short sighted and can still read though and see things close up. I have only been on the drugs 7 months so who knows what will happen. I go see the optician yearly anyway because of the cataracts but it might be a good idea to get your eyes checked if you haven't already. Another thing to check I know but worth it I think.
