Size Chart

The straighter your eyeglass arms the better the lift. Arms can be straightened for a better lift.

There are many factors that determine your best counterbance weight, such as the length and slope of your eyeglass arms, the degree of curve of your eyeglass arms, and the location of the counterbalance fulcrum. All of these conditions are unique to you and your glasses which is why we recommend the pack with all three sizes.

STAFF PICK:  Try all 3 sizes to find your best counter weight plus have weights for multiple glasses.

Works best on straighter eyeglasses arms - the straighter the arms, the better the lift. Many eyeglass arms have a natural curve which works well with these products. However, eyeglass arms that curve down sharply behind your ears will impede the lift, although they will still prevent eyeglasses from slipping. Eyeglass arms can be straightened for a better lift.

Sizing Frequently Asked Questions

What results should I expect?

The number 1 question we get: "Will my glasses float off my nose?". If that happens, you should exchange for a lighter weight. Ideally, you want your eyeglass pressure to be reduced without changing your line of vision.

So even though your glasses may still sit on your nose, you should notice a reduction in the pressure that causes dents, marks, and slipping.

Also, keep in mind that the straighter your eyeglass arms, the more lift you get.




How do I know what size to choose?

Weigh your glasses and compare it to the Size Chart. If you don't know how much your glasses weigh, that is not a problem - just follow the size description. We recommend choosing the option for all 3 weights. This will allow you to find your best counterbalance and have several pairs for multiple glasses.
