Description

The half-eye trial frame is an essential tool in the fields of optometry and ophthalmology, designed to hold trial lenses securely during vision testing and refraction procedures. Its unique half-eye design allows patients to easily look over the top of the frame, facilitating seamless transitions between near and distance vision tasks, such as reading.

Key Features

• Adjustable Fit: These frames offer adjustable pupillary distance, ensuring a comfortable fit for both adults and children. The adjustable temple length and nosepiece further enhance comfort and proper positioning.

• Lightweight Construction: Typically made from non-toxic, non-allergenic materials like metal and plastic, the frames are lightweight yet durable. This construction minimizes discomfort during extended use.

• Safety and Comfort: Anatomically shaped earpieces and a design free from sharp edges ensure safety and comfort for all users.

Functional Design

The trial frame accommodates multiple lenses per eye, usually between two to four, allowing precise lens positioning. Clear graduations on the frame provide accurate readings for axis and base positions, commonly in 5° increments, extending up to 180°.

Versatile Use

These frames are invaluable for various assessments, including:

• Refraction testing for accurate prescription determination
• Measurement of astigmatism and strabismus
• Evaluation of binocular vision

Their versatile design makes them suitable for use in clinical, institutional, and mobile settings.

Maintenance Tips

To maintain optimal performance, the frames should be cleaned with a soft, lint-free cloth and mild detergent. Disinfection with appropriate medical device wipes is recommended, along with avoiding extreme temperatures and impacts.

Conclusion

The half-eye trial frame stands out as a universally adaptable and reliable instrument, crucial for precise and comfortable vision assessment across diverse environments.
