The conditions of buying your contact lenses from Net Optical Australia are as follows.

You must have a valid contact lens prescription from an optometrist or ophthalmologist, and you get your eyes examined regularly to keep your prescription valid. You must have had instruction from your eye care practitioner with respect to the proper care and use of your lenses.

You must wash your hands before inserting and removing your lenses, and if you store your lenses you must use the correct disinfecting solutions and replace this solution each time you store your lenses.  You must wear lenses for their intended number of wearing days only, or as instructed by your optometrist.

If you purchase coloured lenses it is understood that you have tried them with your eye care practitioner and have found their appearance and vision to be suitable.

If you ever get red, sore or uncomfortable eyes when you are wearing your lenses, you must remove them straight away and only use them again when your eyes feel perfect. If problems persist you must see your eye care practitioner for advice.

Currently a prescription is not required for the purchase of Coloured Plano (i.e. no optical power) contact lenses, but all other conditions apply.  An eye examination with your optometrist is strongly advised before purchasing and wearing these lenses.
