"I have used Zenni for years, buying glasses for my entire family. The quality of the lenses is top notch and as my Ophthalmologist agrees - my glasses are always right on target. The frames can vary, but this is true everywhere. I have never regretted any frame selection I have made, they look good, are made well and last a long time. The only drawback is that you can not try them on in advance, but the simulator gives plenty of guidance for me."
