Can I use a different contact lens solution to that recommended by my optometrist?
No, always ask your optometrist's advice. There are many different solutions available, and your optometrist will recommend the care regime that is most suited to your contact lenses and lifestyle. Different solutions work in different ways and they are not interchangeable; one may leave your lenses ready to wear, another may require neutralising before you insert your lenses. If in doubt, always follow the advice of a qualified optometrist.
