Beware of this store. Lack of customer service after I have purchased and picked up my prescription glasses. I purchased the glasses with Crizal Lens and apparently the certificate of authenticity card that was given to me does not allow me to register my lens. Therefore, I do not have sufficient proof that I've purchased Crizal Lens. Not being able to prove this purchase means customer cannot have assurance that all Cohen's optical products are authentic. All I hear from the store manager and the corporate department are excuses and they seem very determined to delay any assistance and express no concern to address this matter. Save your time and take any issues with this store to small claims court.
