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:
- 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.
