 Lenses Edgeing

Each pair of lenses are hand finished after cutting with a precision edgeing machine. Before we ship lenses to our customer, we check the fitting status by installing the lenses to our sample frames. 

--Detail process to finish the lenses and check fitting one by one--

We made final adjustment, one by one by hand, to make sure all our lenses are perfectly fit to your frame and to check the distortion no exist and scratch free before shipping out to the customer.

In our almost 10 years experience, we came to understand and master the skills to cut lenses which will fit perfetly in your X-Metal. The X-Metal were originally hand finished and each frame tend to have a small individual difference, although at a very small percentage.

--Delicate work--

We handle lenses carefully, and we adjust the edge parts of the lenses very attentively.

Policarbonate lenses get distorted easily if using a strong pressed screws.

If you feel dizzy and you may avoid pressing the orbital screw too much.

We do our best to measure each lens with the original sample and they will be perfectly fit into your frames.


 Lenses Distortion
Linegear's lenses which we produce are all 8 base curve lens. Due to high curve lenses, it is easy to have distortion on the edge of the frame. We make effort to avoid such distortion, so it means our lenses are little bit smaller than OEM lenses.

Some user feel very sensitive to lenses distortion. If you feel an uncomfortable from our lenses after you install our lens to your frame, kindly contact us for consultation.

 Light transmission through the lens (Transmissivity)
  We describe about it on Item description for each lens.

How to handle the lenses

Please handle your mirrored lenses carefully, because they scratch easily.

Please remove dirt by washing with water, and wipe it off with a clean cloth or a lens cleaning cloth, when wiping them clean of dirt.

Note: Please check the cloth for dust and powder when wiping your lenses. It may cause a scratch on the lenses.
Do not leave mirrored lenses wet. It could cause discoloration of the lenses.
Do not soak polarized lenses in water for a long time. It could cause damage to their function.
Although the lenses will not be affected when they get slightly wet, please be aware that the lenses are sensitive to water when you use them.
Because polarizing lenses have a polarization plate in between the front and the back,
soaking them in water for a long time will cause the immersion to the polarization plate resulting in malfunction.
Getting some splash will be of no problem, but please keep in mind that
they are not water resistant and handle with care.
If they get stained with greasy dirt, use alcohol to wipe it off.
Never use the paint thinner or sticker remover. The mirror-coating will be damaged.
If you have any question about the lenses, please fill in the inquiry column.
