Three parts of a contact lens wearer's routine are covered by the BioTrue range on this site: the lens itself, the solution it sits in overnight, and a drop for when eyes feel dry partway through the day. Which parts you need depends entirely on what you wear.
Biotrue ONEday is a daily disposable soft lens, with versions for astigmatism and for presbyopia. Daily disposables are opened fresh each morning and thrown away at night, so there is no cleaning step and no case. All three are prescription products, and the parameters written on your prescription decide which version and which powers you order.
The multipurpose solution handles cleaning, rinsing, disinfecting and storage for reusable soft lenses in one bottle. We carry it as a two pack of 10 oz bottles, a Hydration Plus version in the same two pack format, and a 2 oz travel kit with a case. Daily disposable wearers do not need it at all. If you wear two week or monthly lenses, this is the bottle that lives by the sink.
Biotrue Hydration Boost eye drops are preservative free and labeled as soft contact lens friendly, in a 10 mL bottle sold on its own or as a two pack described as 600 or more drops. Preservative free is the format most people choose when they reach for drops several times a day.
Start from what you wear. Daily disposable wearers only need the drops. Reusable lens wearers need a solution, and picking between the standard bottle and Hydration Plus is a comfort preference. Buy the travel kit for a carry on rather than decanting solution into another container, which is not something to do with lens care products. Ask your fitter before changing solution brands, since some lens materials and coatings have their own care instructions.
