It is inevitable that a storing case for contact lenses must be portable and comfortable to carry around. The traditional case is indeed very easy to carry but it can only be useful in combination with a huge and inconvenient to be transported liquid bottle. The combination of bottle and case reduces their conveyance levels to minimum.
Contrariwise, the suggested design reduces significantly the necessity of always carrying the bottle since the case itself has a built-in reservoir able to store liquid for up to 5 days of use. Consequently, the case is an ideal accessory to have for everyday use and especially for travelers.
