New bifocal designs in hyper-oxygen materials

Area of Science:

• Ophthalmology
• Optometry
• Biomedical Engineering

Background:

• The bifocal contact lens market faces challenges due to limitations in current designs.
• Simultaneous vision, common in soft bifocal contact lenses, can reduce visual performance.

Purpose of the Study:

• To explore strategies for increasing the bifocal contact lens market.
• To identify factors influencing the growth of the bifocal contact lens sector.

Main Methods:

• Review of the current contact lens market and existing bifocal contact lens designs.
• Discussion of a new bifocal lens design, including its parameters and clinical study results.
• Recommendations for future bifocal lens designs.

Main Results:

• The Menifocal Z is currently the only hyper-oxygen bifocal contact lens available.
• Analysis indicates that simultaneous vision optical designs negatively impact visual performance.

Conclusions:

• Advancements in bifocal contact lens technology are necessary for market expansion.
• Collaboration between industry and vision scientists is essential to develop improved bifocal lens designs.
• Addressing the visual performance limitations of current designs is key to market growth.
