4 tips to make your glasses last longer

Use both hands. Put on and take off your glasses carefully using both hands.

Set down with lenses facing up. When setting your glasses down, place them so that the curved part of the lens is facing up. Placing them down may cause scratches.

Avoid heat. DDo not subject glasses to heat or wear them in extremely hot areas. The frames may warp or the lenses may crack. Do not leave your glasses on the car's dashboard or other places that receive direct sunlight.

Dry immediately when wet. If your glasses become wet from rain or sweat, dry them immediately. Rust or water may cause stains that cannot be removed.

Handling tips

There is a two week adjustment period for any newly purchased glasses, especially with a new prescription. Do not switch back and forth between old and new glasses with different prescriptions - this will make the adjustment time longer.

If you are a first time Progressive or Bifocals user, it will take time to adjust, as it will limit your depth perception. Be careful going up and down stairs or places with height differences.

Elastic frames such as Airframe are durable and do not break easily but please do not bend or twist it intentionally. It may cause frame distortion.

Through natural wear and tear, the frame may experience some cracks, breakage, or discoloration. The nylon string may break in extreme temperature or from impact.

Please do not wear glasses in the following conditions:

• when you shower or swim.
• in places with extreme temperatures such as direct sunlight, hot saunas or inside an industrial refrigerator. The lenses may change shape, cause distortion, and/or warpage
• if you experience any itchiness, rash or allergies when wearing the glasses, please consult your doctor or dermatologist immediately.
• to look directly at the sun even if you're wearing tinted lenses. It may cause vision loss or severe injuries to your eyes. Avoid using tinted lenses in dark places. Visibility is reduced due to insufficient light.
• when playing high impact sports. Lenses may break when hit by a strong impact. The broken lenses may cause damage to the eyes or face, and could lead to vision loss. We recommend that you purchase sports glasses if you need them for sports.

Cleaning Tips

If your glasses get dirty, please clean it with cold water (and a pea sized drop of mild dish soap if needed), and then use a microfiber or lens cleaning cloth to dry it. Please do not use detergent with alkali or paint thinner to clean your glasses.

When you clean the lenses, hold the bridge of the frame and wipe gently to avoid frame distortion or lens breakage.

JINS SWITCH Plate Guide

JINS SWITCH makes it simple to transition between indoor and outdoor thanks to magnetic clip-on plates. You can now pick-up one or two or a few different plates and SWITCH between tinted, polarized, or driving lenses.

How to carefully put your switch plate onto the frame:

Our Switch Plates will not scratch your eyeglass lenses because they are designed to fit your switch frames exactly. Attaching and removing them carefully makes it very unlikely that you will harm your lenses with a clip-on.

The plates often clip on by the nose bridge, magnet, or hinged arm system. It is highly recommended to not force the clip onto the frame as it should easily attach to the front of the frame. To ensure the clip does not come off, you can test it by seeing how easy it is to remove from the frame or moving your head gently from side to side.

You should also check to see if the plate is sitting correctly on the frame. If you notice there is a small space between the lens and the plate, do not worry. This to make sure that the lenses do not scratch against the plate.

If your switch plate falls out or does not sit correctly on your frame, there could be multiple reasons why this happens!

• Incorrect plate. Double check the plate name and your frame name to see if they match, as well as the dimensions.
• Defective plate or frame (warping issue, can be replaced/exchanged under warranty)
• RX limitations as high prescription can cause your plate to be unable to clamp onto the frame due to the lenses sticking out

Rx Recommendations for JINS SWITCH:

• SPH +2.25 and below
• Similar situations with ADD POWER →
  Example: SPH +0.75 CYL -2.00 ADD +2.50

If you are not happy with your switch frame, you're more than welcome to exchange to a new pair as long as it is within your 30-Day warranty.

Factors to consider when selecting switch plates:

• Ensure that the clips fit securely over your frames—the clips should be the same thickness as your glasses.
• Consider the tint depending on your indoor/outdoor activities.
• Consider bringing a protective case/bag for your plate in situations where you do not want to wear them.
