Anti-Fatigue Glasses Based on Microprisms for Preventing Eyestrain

Area of Science:

• Optometry and Vision Science
• Biomedical Engineering
• Optical Metrology

Background:

• Microprisms are established treatments for strabismus.
• Research on microprismatic glasses for preventing digital eyestrain is limited.
• Digital device usage is a common cause of visual fatigue.

Purpose of the Study:

• To introduce the design and fabrication of microprismatic glasses for preventing eyestrain.
• To develop a theoretical framework for anti-fatigue microprismatic eyewear.
• To create and validate a system for measuring prismatic diopters.

Main Methods:

• Development of a design theory for anti-fatigue microprismatic glasses.
• Fabrication and characterization of microprisms.
• Construction of a compact system for measuring prismatic diopter.
• Performance testing of fabricated microprisms.

Main Results:

• A novel structure for microprismatic glasses to combat digital eyestrain was designed.
• Fabrication techniques and performance characterization were successfully executed.
• A versatile testing system for prismatic diopters was developed and validated.
• Experimental results align with theoretical calculations.

Conclusions:

• The study presents a viable design and fabrication method for anti-fatigue microprismatic glasses.
• A new system for prismatic diopter measurement is introduced, applicable to various prism types.
• An objective prismatic diopter of 2.0-3.0 Δ per eye is suggested, pending clinical validation for subjective optimal values.
