User Guide

For first time glasses wearers, a period of adaptation may be required, especially for progressive lenses wearer. For experienced glasses wearers (with new lenses), a period of adaptation may be required especially when there is a change in prescription. Please pay attention when going up and down the stairs.

Progressive Lens

For progressive lens, different areas of the lens are used for different viewing distances.

  • Far vision area
  • Intermediate area
  • Near vision area
  • Peripheral area

You will soon learn and adapt to the slight “swimming” effect at the peripheral area within a week.

 

Instructions

While looking through different areas of the lens, the center of each area on the lens will provide a better vision.

Looking at far distance : Use the Far vision area which is located at the top part of the lens.

Looking at intermediate distance :  Use the intermediate area at the center of the lens, when talking to people, doing window shopping, or looking at a computer screen.

Looking at near distance : Bring your chin forward in order to look into the near vision area.

Occupational Lenses

Different areas of the lens will be used according to the distances.

  • Near vision area
  • Intermediate area
  • Peripheral area

You will soon learn and adapt to the slight swimming effect at the peripheral area within a week.

 

Instructions

While looking through different parts of the lens, the center area at each part of the lens will provide a better vision.

Looking at near distance : When reading a book or newspaper, look through the near vision area.

Looking at far distance :   Use the intermediate vision area on the top part of the lens, when talking to people, doing window shopping or looking at a computer screen. 

* Viewing distances differ for Occupational Lenses depending on the age or accommodation ability.

Safety Precautions

Exposure to strong impact may cause damages to both glass and plastic lenses. Specific spectacles are purchased for use in sport, such as football, cricket, etc, as regular spectacle lenses do not generally provide the adequate protection required for this type of activities.

Beware

  • It is dangerous to drive with high density color lens, especially in dark tunnel and/or in the evening/at night.
  • While driving, do not wear bright lenses such as green, blue or red as it may cause difficulties to identify traffic light colors.
  • Please refrain from driving with lens with a tint density over 25% (light transmittance less than 75%) in the evening and/or at night.
  • Exposure to strong impact may cause damages to both glass and plastic lenses. Specific spectacles are purchased for use in sport, such as soccer, baseball, etc, as regular spectacle lenses do not generally provide the adequate protection required for this type of activities.
  • Please be aware when driving into tunnels wearing tinted or photochromic lenses since sudden dimness of light may cause visual difficulties.

 

 

Caution

  • Please refrain from looking directly at the sun even with sunglasses as it may cause serious damage to the eye, leading to blindness.

  • Please do not wear Soltes Wide lens when using the stairs.
  • When driving or using the stairs, do not use reading glasses as they are meant for near vision purpose only.
  • When walking with progressive lenses, the perception of depth may be different especially when viewing with near vision area in the lens. Bring your chin down to view through the far vision area in the upper part of the lens.
