Circle lens contacts  are an increasingly popular style of colored contact lens, particularly among young women. They’re also called big eyes or Korean lenses, because they make your iris appear larger than it actually is.

These types of lenses are sold in yearly disposable formats and are available in a wide range of colors. Usually, they’re worn in the same way as regular contacts. The lenses feature a transparent center and an extra-wide outer ring that’s tinted.

It’s a fun and easy way to make your eyes look unique. And if you’re a fan of Lady Gaga, you’ve probably seen them on her in the music video for “Bad Romance.”

This style of lenses are a little more challenging to find than other styles. But with a little research, you can find them online.

Circle Lenses vs Regular Contact Lenses: Which One is Right for You

The trend began in Asia and became popular with younger American women in 2010 after a video demonstrating how to get a “crazy, googly” Lady Gaga eye went viral. YouTube star Michelle Phan filmed a tutorial on how to create the look, and it has since racked up more than 48 million views.

One of the best ways to find circle lenses is to search the web for stores based in Asia. These companies often carry thousands of designs in a variety of colors and patterns.

They’re generally more affordable than prescription glasses, but they also have a shorter lifespan and can cause discomfort and dryness. So be sure to wear them only after a doctor’s approval and buy from a reputable retailer.
