Jami,
I have been on Met for two years, and I also sit in front of a computer screen quite a bit. I have always had perfect vision until last year. In September, I was diagnosed with cataracts in both eyes. I was shocked (especially since I have yearly eye exams, and cataracts are usually discovered during an eye exam before any symptoms appear!) Anyway, I've been dealing with crummy vision for months now, and I finally went to a surgeon for a consult and I am having cataract surgery on my left eye, which has a "significant" cataract, the first week in May. I will eventually need to have the surgery for my right eye as well, which has a large cataract as well (but it isn't bothering me as much as the left eye).
The doc is blaming the cataracts on my diabetes, but I don't buy that since I was just diagnosed two years ago and have had my blood sugars under control since then. I have always gotten a fasting blood sugar test each year at my physical, so it's not like I was walking around with uncontrolled diabetes for a long period of time. So here's my theory: I think it's a combination of Met and the computer screen. The reason I say that is because Met can make you photosensitive (which is why you have to be very careful if you're out in the sun for a length of time). If that's the case, then it can make our eyes photosensitive too. One known cause of cataracts is the UV rays from the sun. So maybe Met can accelerate the damage? There is still so much they don't know about the cause of cataracts and there is no way to know for sure. What I do know is that the type of cataracts I have are not the type caused by aging (which are nuclear cataracts). The kind I have (supracapsular, in the back of the eye) is usually caused by diabetes, sun damage, trauma, or medications (althought there is no known link between Met and cataracts). Another known cause for these types cataracts is long term use of steroids. I was on dexamethasone for about a year after I was first diagnosed with PCOS about 20 years ago; who knows, maybe that contributed to my cataracts.
Anyway, your symptoms sounds a lot like mine, with the off and on blurring, and I suggest you get an eye exam to rule out cataracts. I found out that they can happen at any age!
Good luck,
Linda
