We keep Biotrue Multi-Purpose Contact Lens Solution, 300 ml on our visual care shelf alongside 48 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: Purpose Solution is inspired by the biology of eyes to make wearing contact lenses easier on eyes. It works in harmony with eyes to help lenses stay clean and moist. BIOTRUE contact lens solution provides excellent cleaning and disinfection. It removes debris and protein buildup for clean, clear lenses. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.7 out of 5 from 6,317 ratings. We work out below what that is worth against everything else on the shelf.
The typical visual care product on our shelf scores 4.5 out of 5, measured across 49 rated products. This one comes in at 4.7. That puts it in the top quarter of the shelf. Most things here rate well, so what matters is the gap to the pack rather than the number on its own, and the gap is real. Weighted for review volume, we place it third on this shelf.
That score rests on 6,317 ratings. The median for this shelf is 1,524. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.
On money, this sits in the top third of a shelf running from £3.59 to £31.50, with the midpoint around £8.99. It costs more than most and is rated above most, so the premium at least tracks something buyers recognise.

Short on time? Our best visual care shortlist narrows this shelf down to a handful.
