Question by whatever: Are there any safe, reputable online optician stores that sell cheap high index lens?
Many local opticians have warned me about the lack of quality of lens bought online for single vision eyewear. I am reluctant to buy these lens online because my prescription is so high? What do you think?
btw, is there any real size and weight difference between high index 1.67 and 1.71? Many opticians tell me that the difference isn’t worth the cost because there isn’t much of a difference (.04 improvement versus a .07 improvement with the 1.67 if upgraded from a 1.60). I have seen the difference between the 1.60 and 1.67 and it’s very apparent.
btw, my prescription is -650 and -700

For the second part of your question, you were told right.
The 1.71 may be worth it only if your prescription is over – 8.00 Diopters.
One of the most important things in high prescriptions is the frame choice. The wrong choice can add a lot of unwanted thickness to those lenses , no matter what index they are.
As for the first part of your question , I would rather be fit for glasses by someone who has seen me, taken the proper measurements and will give me service after if a problem arises.
My local economy is more important to me also , than supporting Hong Kong’s economy.
