PITTSBURGH (KDKA) — You can buy just about anything online these days.

Americans spend more than $700 billion on online purchases last year alone.

That includes prescription eyewear, which is a growing trend, especially among women.

Angie Stocklin of online provider Felix and Iris says consumers’ number one concern is getting the right fit, and that any reputable retailer will have an optician on staff to make sure that happens.

“We lead you right through the process. We’re going to ask what kind of lenses do you need. Is it single vision, is it progressive, is it a bifocal lens?” said Stocklin. “We’re going to show you how to put in all of the measurements from your doctor, which is your prescription, your pupillary distance and walk you straight through the process online. It’s really self-explanatory and anyone can do it.”

“When talking to your eye doctor, let them know you are going to order online because you want as many details as possible, especially the distance between your pupils so you have a good fit of your lenses,” said Angie Hicks of Angie’s List.

Once the measurements are in, you can browse dozens of online sites for frames. Many let you virtually try on the glasses if you upload a photo. They’ll also send you sample frames to try on in real life, another appealing convenience.

“I will definitely do it again,” said Brooke Padilla. “I’m considering going online to buy prescription sunglasses. Buying glasses online worked for me, but it may not work for everyone. I would suggest you have that conversation with your doctor and then research your options because there’s tons of options available today.”
