zLens 对比 Lensy - Contact Lens Tracker 的使用情况和统计数据

Lensy is your Contact Lens Tracker. Lensy automates everything in the best possible way. The change date and the number of remaining lenses automatically update without any interaction. You simply enter the kind of lenses you wear and when you started wearing them. Then, Lensy calculates your change date. When the date is reached, Lensy calculates your new change date and also reduced the number of remaining lenses. Lensy can send notifications to remind you about changing your lenses. Lensy has a view where you can add all your prescriptions values. You can also separate the values between your left and right lenses.
