Hey Jim - How did these glasses turn out? I wouldn't mind having a few pairs of inexpensive single vision glasses (for piano and computer). I went to their website and can't say I was impressed with their mastery of the English language. Hopefully their mastery of optics is better. This company must not be in the US, and we could be dealing with one of those laughable Chinese-to-English translations.
Example:

This doesn't make much sense: "Without PD – it is impossible to purchase an accurate pair of glasses as it pronounces the optical center of both pupils."
OK, I understand that PD is good, but what the heck does "pronounces the optical center of both pupils" mean?
And I'm not even going to make a guess about what they were trying to convey with this: "However with deprivation – our eyesight absorbs erroneous frequencies." ??? I'm pretty sure you won't find that line in many ophthalmologist medical textbooks.
But the real proof is in the quality of what you received from them. How did that turn out?
