Distilled water and what kind of salt make saline solution for contact lenses?
Make your own saline solution Can it be done? Yes, you can make your own saline solution for contact lenses or nasal sprays / drops very cheaply because the main ingredients are just water and salt. In years past I made my own saline at home and used it for lenses without any problems whatsoever. I have lately reverted to buying commercial saline mainly out of convenience / laziness, but the added safety is a bonus. If you want to make your own saline, here’s how to do it with some thought towards reducing the risks, along with a couple of other tips on minimising costs. The below is written largely for contact lens use, with a heavy emphasis on sterility, but there’s no harm in following these steps if you are planning to use the saline as a nasal spray either. For one thing, you will be able to store a larger quantity of your solution for longer periods of time with greater confidence. WARNING! You can damage your eyesight and even cause PERMANENT BLINDNESS if sterility is compromise
