A trial lens set, also known as a trial lens kit or trial frame set, is a collection of lenses used by optometrists and ophthalmologists during eye examinations to determine a patient's prescription for corrective lenses, such as glasses or contact lenses. These sets typically contain a variety of lenses with different optical powers and specifications, allowing the eye care professional to conduct a comprehensive refraction test and find the most suitable prescription for the patient. Lens Types: Trial lens sets typically include spherical lenses, cylindrical lenses, and prism lenses. Spherical lenses correct for nearsightedness (myopia) or farsightedness (hyperopia), while cylindrical lenses correct for astigmatism. Prism lenses are used to correct alignment and binocular vision issues.
Lens Powers: The lenses in a trial lens set come in a range of powers, usually measured in diopters (D), which indicate the strength of the lens. Positive (+) powers are used to correct hyperopia, while negative (-) powers correct myopia. Cylinder lenses also have a cylindrical power component to correct astigmatism.
Lens Diameter and Thickness: Trial lenses come in various diameters and thicknesses. Thicker lenses may have higher powers or prisms, while smaller diameters are used for more precise testing.
Lens Material: Trial lenses are typically made of high-quality optical glass or plastic materials that provide accurate refractive properties and durability.
Mounting System: Trial lenses are often mounted in metal or plastic rims that fit into a trial frame. The trial frame allows the eye care professional to hold and position the lenses in front of the patient's eyes during the refraction test.
Accessories: Some trial lens sets may include additional accessories, such as lens holders, lens cleaning tools, and a carrying case for convenient storage and transportation.
During a refraction test, the eye care professional uses the trial lens set along with a phoropter or trial frame to present different lens combinations to the patient and determine the best prescription for optimal vision correction.
Our PC-55 (45% Omafilon C & 55% Water Content) Soft Contact Lenses are suitable for most lens wearers. The lenses are more resistant to friction. Therefore, they are more durable for monthly wear.
Our PC-55 contains MPC, a hydrophilic biomimetic material that occurs naturally in human eyes. MPC creates a cushion of hydration against the surface of your eyes to keep the lenses hydrated while preventing protein and lipids buildup for long-lasting hydration and all-day comfort. MPC is integrated right into the lens, so it won't wear off or dissipate like a coating.
The aspheric optical design of our lenses matches the curve of your eyes and reduces spherical aberration, giving you superior vision correction throughout your entire field of vision.
Our lenses with built-in Class II UV blockers protect your eyes from an average of 97% of UVB and 87% of UVA radiation.
We are happy to organize our Contact Lens Samples to your doorsteps for evaluation.
Our PC-58 Toric Contact Lenses for astigmatism were introduced after countless hours of research and development. The lenses are incorporated with our unique double slab-off prism ballast design, which helps to reposition the lens correctly on the eye after each blink so that the lens fits, feels, and focuses just right, every time.
Like our Aspheric lenses, the lenses contain MPC, a hydrophilic biomimetic material that occurs naturally in human eyes. MPC creates a cushion of hydration against the surface of the eyes to keep the lenses hydrated while preventing protein and lipids buildup for long-lasting hydration and all-day comfort.
