I am on my fourth pair of glasses. I need all the lense add-ons (anti-reflect, scratch resistance, and light-weight progressive. Initially had one year lense warranty but now 6 months. I know why because at one-year the reflective coating starts coming off and scratches are susceptible. Then they want to sell replacement lenses for $195, or buy new glasses. The product support has deteriorated.
Tip for consumers: Good price until lenses deteriorate at one yr or less with only a 6 month warranty.
