I think unless you're a chemist with access to sterile water etc it just wouldn't be possible / advisable.. You just need to be really careful with anything yr gonna put in ur eyes!
nooooo....don't use any type of water with contact lenses! You can't make up saline urself unfortunately it's just a base product with nothing in it that will react etc. hence why chemists use it just to make up volumes.
Thank you all for your honest opinions of my thoughts.
It would appear that just adding a salt tablet to distilled water is not a good idea as it requires sterile water, although what the differance is I don't qute know.
Thank you anyway.
