A trial lens set is a collection of lenses used to determine the correct prescription for eyeglasses or contact lenses. These sets typically include a variety of lenses with different powers and types, such as spherical, cylindrical, and prismatic lenses.
Types of Trial Lens Sets:
- Full-aperture trial lens sets: These sets have lenses with full apertures, allowing for unobstructed vision during exams. They often come in metal or plastic rims and may include accessory lenses.
- Compact trial lens sets: These sets are designed to be more portable and space-efficient, making them ideal for mobile practitioners or small clinics ¹ ².
Features to Consider:
- Lens material: Glass or high-quality plastic lenses ensure accurate and reliable results.
- Rim material: Metal rims are durable, while plastic rims are lighter and more resistant to corrosion.
- Number of lenses: Sets can range from a few dozen to several hundred lenses, depending on the intended use and practitioner preference.
- Accessory lenses: Some sets include additional lenses, such as prism lenses, Maddox lenses, or occluders, to facilitate more comprehensive eye exams ¹ ² ³.
