Hello, so about four weeks ago my left eye got blurry. I hardly can read with it and it seems that my eyes are more sensitive to sunlight. I wear sun shades every time I drive while it's sunny. I never had that issue before. I went to pearl vision to get my eyes checked and they couldn't find the cause for my lack of vision in my left eye. My eye pressure is at 15 which is considered to be in the normal range, so I know it's not Glaucoma. They said I might need new glasses(I've had my pair of glasses since late 2011). So now I'm going to see an eye specialist in about two weeks. Does anyone here have any idea what could of cause this? I mainly want to know why my vision has gotten blurry. Do I just need new glasses or is it something more serious?

Thanks
