Not all lenses are priced the same — and your prescription is the biggest reason why. From affordable zero-power lenses to premium progressive multifocals, every element of your Rx — the power range, cylinder value, lens material, and coatings — plays a role in determining the final cost. This guide breaks down exactly how lens pricing works across all categories, so you can make smarter, more informed choices when ordering your next pair.

Photochromic and tinted lenses both protect your eyes from sunlight, but they work in different ways. Photochromic lenses automatically darken when exposed to UV light and become clear indoors, making them ideal for everyday use. Tinted lenses, on the other hand, provide a fixed shade designed for consistent glare reduction, especially for driving and outdoor activities. This guide explains the key differences, advantages, and best use cases so you can choose the right lenses for your lifestyle.

Picking the wrong lenses can cost you comfort — and money. Here's the simple truth: Single Vision corrects one distance. Progressive lenses correct all three — near, intermediate, and far — in one seamless lens. If you're under 40, single vision is likely all you need. Hit 40+? It's time to talk progressives.
