Visible Date
Visible Date

The using period of contact lenses are divided into a day ,a week ,a month ,six  month and a year.  When we use the contact lenses,we often forget how long we have used and whether the lenses are expired or not. This will mislead us continuing using the expired  lenses,
which will make our eyes hurt a lot.
“Visible Date”is a new contact lens box design. When you begin to use
 one new pair of lens you can record the date ofbeginning day in these 
lens contact box by using the rotary disk. These lenscontact box have
 a function of remind of users and record the date . Thus youcan use your 
contact lens safely without worried.
