about customized glasses

about multifocus reading glasses, we can do any degree. just the price is different.
1.If your degree is between -3.00 and +3.00 without cylinder degree (astigmatism degree), ADD is from +1.00 to +3.00 , then you do not need to buy customized glasses with astigmatism.

2. if your two eyes are with cylinder degree (astigmatism degree), then you have to buy customized glasses whose handling time is about 10 working days. And the price will be higher then the nomral ones. Here we use 4.0 Germany OPTO TECH. There are four kinds multifocus progressive lens:
A. blanced type---no additional requirment.
B. for driving--then you need more area for the up degree which is used for looking far.
C. for reading--then you need more area for the bottom degree which is used for looking near.
D. for computer/office--then you need more area for the middle degree which is used for looking middle.
you need to know what type do you need and tell us your requirment. Here we also have the pics for you.
