If anyone wears these please be aware that there are some faulty batches that are in circulation. This has just come out today.
They cause irritation with small particles in either the solution in the packaging or on the lens itself which could cause corneal abrasions.
You can check details if you search for the above info (for some reason I cannot paste the links).
I rang my lens suppler this morning, they knew nothing about it nor did my optician, pretty poor from J&J as the press reported this before people are being told from their practitioners.
I have worn lenses for almost 40 years, and use these lenses myself, but I will be changing to another brand.
