Improvised Contact Lens Solution
Discussion
The proprietary stuff isn’t just sterile saline, its distilled water to take out other mineral impurities.
Then the level of salt content has to match that normally found in tears.
Get the saturation level wrong and it will draw moisture out of the eye tissue. This isn’t good for your eyes and will sting.
Certainly you can make it correctly, given the right equipment and measuring apparatus. The chances of you having that around the average house are nil.
Even if you have the equipment to do a little home chemistry, it’s not worth your time and effort compared to buying it.
Knock on a few neighbours doors, or phone a friend, you will be able to borrow some.

I've got both but prefer the monthlys for working longer days etc. - I can keep them in much longer.Says he who's worn his glasses today.
All sorted now though - Sainsbury's coughed up the goods and I won't be going blind (for lens related reasons) this evening...

I have been wearing contacts for over 20 years so here is my 2 pen'th worth. Use some boiled water, let it cool obviously, put a TINY amount of salt in it i.e one salt crystal. Then tomorrow go to the chemist and get some proper stuff!
He's got some, don't worry...HTH...
