Sunglasses are more than just a fun fashion item. For many people, they are needed for health. Sunglasses protect your eyes from harmful UV rays from the sun. Excessive UV exposure can harm your eyes and affect your vision over time. Sunglasses also cut down on glare. Glare is when bright light gets in your eyes. It can make it hard to see and cause eye strain.

About 41 million people in America wear glasses or contacts. Some of these people need prescription sunglasses too. The glasses help them see clearly in the bright sunlight.

Given the multitude of sunglasses available for purchase online, how do you select the ideal pair? 

There are lots of things to think about, like sizes and lens types. Buying prescription sunglasses online can be confusing. This guide will walk you through what to look for when buying prescription sunglasses online.

Frame Size & Shape

Finding the right frame size and shape for your face is key to maximizing comfort and style. Here are some tips:

Oval Faces

The oval is the most versatile face shape. You can pull off almost any frame style. Avoid oversized frames which may overwhelm your features.

Round Faces

To contrast your softer facial curves, go for rectangular frames with strong lines. Avoid round and oversized frames.

Square Faces

Choose rounder, curved frames to soften the angles of your face. Avoid boxy, angular frames.

Heart-Shaped Faces

Look for wider frames that balance out a narrow chin. Cat-eye frames are a great option.

Take measurements of your face width and consider getting fitted in person if unsure. Once you’ve determined the face shape, examine the frame dimensions listed online. Models with similar face shapes can provide examples of good fit.
