Compensatory lenses: are lenses to compensate for a vision problem such as nearsightedness, farsightedness, astigmatism, and presbyopia.

Treatment lenses (performance lenses) have a therapeutic effect and are used for things like:

  • relieving eye strain

  • encouraging eye movements

  • providing focus change

  • enhancing peripheral vision

Often times these are prescribed as reading glasses or multifocal lenses. The multifocal lenses we use for children are for anti-fatigue design as compared with progressive lenses traditionally used for adults.
