Clip On Sunglasses Sizing Help

Clip on Sunglasses For Prescription Glasses


We have several different generic clip-on shapes available for eyewear frames. 

Please note that we do not recommend clip-on sunglasses for rimless or semi rimless glasses.

Please note that if the rim or lenses of your glasses is over 3 millimeters thick, the clip-on will not attach to the frame properly.

To find a clip-on on our website using the measurements of your frame, please follow the example directions below.  Please note that measuring your glasses is the only way to pick a clip-on that might fit, your frame model name or numbers written on the inside of your temples will not help with sizing. 


Example Frame

In the example above the width is 56mm to the outside of the lens rim and the height of one lens is 39mm height to the outside lens rim.

Next look at the the clip-on shapes below these directions to find the closest clip-on similar in shape to your glasses

In this example the rectangle shape is the closest shape to the example eyeglass frame. The rectangle shape clip-on would be a pretty good fit for this example. The measurements from our example eyeglass frame above were 56mm width x 39mm height. The best size available for rectangle clip on sunglasses would be the 56mm width x 40mm height. Always go to the next bigger size when in-between sizes. We rarely get this lucky as in the above example when picking a pair of clip-on sunglasses because there are so many different shaped frames out there on the market. Your goal is to get as close as you can to the right shape of your glasses.

*** Important notes: The clip-on should never be too snug. The clip-on lens should not rest on your glasses. 

Always clean the lenses on your prescription glasses before attaching the clip-on.

Please be careful when trying on clip-on sunglasses, never put on a pair of clip-on sunglasses that is too small or force a clip-on sunglass to fit. We cannot be responsible if you accidentally scratch one of your lenses. If it looks too small or feels too tight, please send the clip-on back for a refund. If you have an expensive pair of eyeglasses, rimless eyeglass frames or semi rimless, we do not recommend clip-on's for those type of frames.

Once again if the clip-on does not fit correctly, please return them by regular first class mail to:
