While it’s true that eyewear adjustments are best left to the professionals, sometimes in a pinch it helps to get glasses to, well, stop pinching.

To solve minor fit problems like pinching, sliding and slanting, Zenni Optical created a how-to guide to adjusting eyeglass fit depicting a few common problems with frame and lens placement and easy solutions to getting on-the-go glasses back where they belong—in front of your eyes.

Take a peek at the DIY Guide to Adjusting Your Glasses posted on Zenni’s website to get those wires and temples in place. Then, make sure you consult an optician or make an appointment with an eyecare professional so you know your new fit is the right fit.
