Description Of Item: Transparent light grey plastic barrel type contact lens case 57 mm x 30 mm diameter with cream octagonal shaped screw cap and hinged lens baskets on a central stem.

Historical Significance: Cases of this type were included in AOSept Starter Kits. The vent hole allowed oxygen produced in the neutralisation of hydrogen peroxide to escape through a flap valve in the cap. The platinum coated ridged device provides a catalyst to neutralise the hydrogen peroxide in the AOSept solution. AOSept was originally developed by American Optical and purchased by Ciba before being included in the Alcon spin off.
