For customers currently using contact lenses.
Your contact lens box contains the information you need such as power, diameter and base curve.
For new users or customers who do not have their contact lens boxes.
You need to use the most updated prescription provided by your ophthalmologist.
Once you have purchased lenses, you can find the necessary data in your prescription or contact lens boxes and use that for future orders.
You will need to have PWR (power), BC (base curve) and DIA (diameter) information before you place an order. If you have been given a prescription for astigmatism you will need to have both CY (cylinder) and AX (axle) data as well.
Are BC and PWR different depending on the lens manufacturer?
Because of global standards, all manufacturers must use the same notation for PWR and BC. However, lens size, thickness, design and processing methods are different depending on the brand and the manufacturer. If your contact lenses have been prescribed for astigmatism, your view will be different depending upon the manufacturer. We strongly suggest having your eyes checked as directed by your ophthalmologist and following his/her guidance on lens selection.
Is it possible to use contact lenses if the DIA is different from my prescription data?
We strongly suggest having your eyes checked as directed by your ophthalmologist and only with his/her confirmation should you use lenses with different DIA.
I cannot find lenses for far-sighted eyes (+) in the POWER list.
The lenses for far-sighted eyes (+) and progressive lenses are currently not available at our website. The starting date has not been scheduled yet. We apology for the inconvenience.
Contact lenses are a medical device and care must be taken when ordering.
When you place an order with us, please make sure to choose the prescription that was given to you by an ophthalmologist or qualified physician in the u.s.
