I have very sensitive eyes when it comes to contact lense solution. I tried a few different ones and they all seemed to burn and then my eyes would be bloodshot for a few hours. My eye doctor told me to try the Bausch & Lomb Sensitive Eyes saline solution as an alternative. I went to the drug store and picked some up. I even happned to catch them on sale. I got 2 bottles for $4.
That night I let them soak in the solution and cleaned them before I put them in my eyes. I was so relieved that they didn't burn at all and they felt so clean at the same time. I have used this product ever since.
On the box it says that the saline solution is a preserved thimerosal-free saline solution made for people with sensitive eyes. I am personally not an optometrist and I am not sure what that means exactly, but I do know that my eyes never burn or sting and I am very satified with the product.
