Patient Education
Anti-Reflective: Coating that is either applied to the lens surface or embedded in to allow for superior scratch resistance. Significantly reduces reflections, or unwanted glare, off the lens surface to provide the sharpest, clearest vision from your eyewear. Improves reaction time during nighttime driving and reduces eye strain and fatigue from bright overhead lights and computer screens.
Freeform Lenses (High Definition): Conventional prescription lenses are molded with a predetermined curve and the prescription is ground from the backside of the lens surface by a lab technician to create your prescription. Freeform technology begins with a flat lens and utilizes precise computer programs and surfacing equipment to customize your prescription lenses to match the positioning of your eye and how your glasses are worn. Strongly suggested for first-time progressive wearers because of easier adaptation time and wider areas of viewing than traditional progressives/single vision lenses.
Transitions: Polymer inside prescription lenses that activates, or expands, when in direct contact with UV rays from sunlight. Available in gray or brown, they are variable condition lenses that will darken when outdoors and clears when indoors. Option available that will darken (moderately) behind your car’s windshield.
Polarized: Filter embedded in lens that reduces sun glare off of reflective surfaces, such as water, sand, snow, and paved surfaces. UV glare is much stronger when a reflective surface is introduced so when considering prescription sunglasses, this is recommended to further protect your eyes from distracting and sun glare.
CR-39: Plastic lens material meant to be used for lower prescriptions. Can tint as sunglasses, but an additional scratch coating must be applied to make them scratch-resistant.
Polycarbonate: More durable and impact-resistant than traditional plastic, this lens material is recommended for children and for safety-related work and other activities (sports glasses/goggles).
Trivex: Form of plastic that is 10% lighter, just as impact resistant, and wearers indicate sharper vision because of less color dispersion than polycarbonate lenses.
High Index: Lightweight, super scratch-resistant plastic material that has the ability to be ground thinner. Cosmetically appealing and meant for higher prescriptions where thickness and weight matter the most.
