Prescription Lens Coatings Guide — Anti-Glare, Scratch, UV & Blue Light Explained
Coating names and bundles vary by retailer. Compare the exact lens material, treatment description, configured price, care instructions and warranty. This page summarizes public product categories; it does not report a lab or wear test.
The 4 Lens Coatings — What They Actually Do
1. Anti-Glare (AR) Coating
Retailers describe anti-reflective treatments as reducing surface reflections. Ask for the exact product name, which lens surfaces are treated, the care instructions and the coating warranty. Suitability depends on the wearer and use case; no universal recommendation is made here.
2. Scratch-Resistant Hard Coat
A hard coat is intended to improve resistance to everyday surface damage, but no spectacle lens is scratch-proof. Check whether it is included with the selected material, what the warranty covers and which cleaning methods the retailer requires.
3. UV Protection (UV400)
UV claims can come from the lens material, a treatment or both. Look for the retailer's stated wavelength range or applicable standard for the exact configured lens instead of assuming that every material or package is identical.
4. Blue Light Filtering
Blue-light products differ in spectrum, transmission and tint. Ask for a published transmission curve or clearly defined specification, and discuss persistent eye strain or sleep concerns with an appropriate professional rather than relying on a marketing label.
Coating Comparison Questions at Checkout
| Option | Included with material? | Specification to request | Care or warranty question | Quote checkpoint |
|---|---|---|---|---|
| Anti-reflective | Check the selected lens package | Product name, treated surfaces and stated performance | Cleaning method and coating warranty | Compare the same AR tier |
| Hard coat | Check material and package details | Scratch-resistance description | Exclusions for scratches or misuse | Avoid counting an included treatment twice |
| UV protection | Check material-specific listing | Stated wavelength range or standard | Whether protection is inherent or applied | Match the exact lens material |
| Blue-light treatment | Usually a separate named option | Spectrum, transmission and visible tint | Remake terms if tint is unsuitable | Compare only products with like specifications |
Build a Like-for-Like Lens Quote
Use one prescription and one lens material, then add only treatments with comparable published specifications. Record the delivered total and warranty for each quote. A cheaper label is not necessarily the same product, and a premium label does not prove better performance.
