This Lens-Mate Contact Lens Case is the ideal solution for storing and cleaning contact lenses. Suitable for both soft and hard lenses, simply fill the wells up with cold chemical disinfectants to clean and disinfect. Lids are attached, not screw on, so they never get lost and they don't leak. This is a two pack of lens cases only. Disinfectant and lens cleaners are available separately. Left and Right clearly marked on top of the lids. With attached lids, the case can be used one-handed. The snap top is easier and quicker to use versus the screw on tops. When closed, each lid meets the base, so it's a tight closure to keep lenses covered in solution. Solution won't evaporate and won't leak. Unlike cases with screw on lids, the wells are smaller, so less solution is needed. Perfectly sized for convenience. Case will fit in any pocket or purse. Keep one case at home, keep the other hand for on-the-go.
