Clark is into wearing cheap prescription glasses that don't skimp on style, as you may know if you've ever seen him on TV.
Many years ago, a listener shared a tip about
ZenniOptical.com, which offers prescription glasses at $8 ($12 with shipping) for complete frames and lenses.
Clark's progressive lenses with some additional add-ons cost him a whole $37 -- nothing compared to what it might have cost in the past.
Yet Zenni has created so many Clark Stinks postings. One of the chief gripes is that Zenni doesn't offer any customer service after the sale. Even more vocal criticism came from people who are in the eyeglasses business themselves. But Clark had his Zennis vetted by a professional and the optometrist could find no fault with them!
In reality, Zenni has been an industry changer. Now you have competitors like
EyeBuyDirect.com and
GlassesUnlimited.com offer prescription glasses at similar price points. It's a wide open field.
