A novel sliding lens system creates a simple, low-cost variable prism. This design offers a practical alternative to traditional rotating prisms for ophthalmic applications.

Area of Science:

  • Ophthalmology
  • Optical Engineering

Background:

  • Variable-power prisms are essential tools in ophthalmology.
  • Conventional rotating prisms can be complex and costly.

Purpose of the Study:

  • To develop a simple, low-cost variable-power prism.
  • To incorporate a linear scale for precise adjustments.

Main Methods:

  • Construction of a sliding lens system.
  • Utilized the prismatic effect of standard ophthalmic lenses.

Main Results:

  • The system demonstrated effective functionality at low powers.
  • Conventional curved ophthalmic lenses were successfully employed.

Conclusions:
