Looking for the perfect glasses: where to buy?

I need advice: where is the best place to buy glasses? The choice in stores is huge, and this only complicates the task. I want to find something really worthwhile, but I don't know where to start looking. Which online stores offer the best selection and quality? Does it make sense to buy glasses online, or is it better to go to an offline store? What brands are the most popular now? Should I pay attention to customer reviews, or are they not always objective? I'm looking forward to your recommendations and experience because I want to make the right choice.
