I’ve Worn Contacts For About 5 Or 6 Years And Got New Ones But Now My Eyes Dry Up And I Cant Wear Them.

I have been wearing contacts for about 5 or 6 years but recently got a new eye prescription and they told me they longer made the contacts I wear. I have tried a few new brands out but they simply dry out my left eye (it is a toric lens for astigmatism). Could I have a problem with my eye or am I just unable to get used to a different material in the lens itself? I cannot keep it in my left eye for more than a half hour but my right eye (normal contact) feels fine. I have been interning in a datacenter this summer which uses a complex air conditioning system and the problem has gotten worse since being here. Any ideas?

The Best Contact Lense For Astigmatism That Can Be Worn Overnight?

I am going to buy some contacts online, I want a contact lense that can on occasion be worn overnight, but my options are limited because of my astigmatism. I have already tried purevision torics and acuvue oasis (the purevisions were better) but it has been a while since i have purchased contacts and was wondering if there is anything new out there or if anyone has tried some and have a preference or a recomendation, thank you.

Worn Out Retina, A Big Problem?

I went to get glasses today and the doctor told me that I have a part on my retina that is worn out; he explained that this is normal in people with astigmatism. He did warn me that if I ever start seeing white flashes or constant floaters that I should go back to him as soon as possible. He gave me the feeling this was not such a big deal, but I am still scare that I could get a detached retina; he did say that there is a 1% chance of this happening. I am very unlucky and I am scared. Should I be worried? Should I look for another doctor, maybe there is a treatment to prevent the actual detachment or any further worn out of my retina.
Please give me some advice.
