What is GlassesPedia?
GlassesPedia is a free reference for anyone who wears glasses, is thinking about getting glasses, or simply wants to understand how corrective eyewear works.
We started this project because we noticed something: most information about glasses online is either written to sell you something, or written in clinical jargon that assumes you already know what you're reading. There's very little in between — practical, plain-language information about lenses, frames, prescriptions, and coatings.
That's the gap we're filling.
What We Cover
Our articles span eight core categories:
- Lenses — Progressive, bifocal, single vision, photochromic, blue light filtering, and specialty lenses.
- Frames — Every frame shape and style, materials (acetate, metal, titanium, TR-90), sizing, and face shape matching.
- Prescriptions — How to read your prescription, what SPH, CYL, AXIS, ADD, and PD mean, and when to get updated.
- Coatings — Anti-reflective, blue light, scratch-resistant, UV protection, hydrophobic, and photochromic coatings.
- Sunglasses — Polarization, UV ratings, tint colours, prescription sunglasses, and sports eyewear.
- Eye Conditions — Myopia, hyperopia, astigmatism, presbyopia — what they are and how lenses correct them.
- Care & Maintenance — Cleaning, adjustments, scratch prevention, storage, and common fixes.
- Buying Guide — What to look for, what to ask your optician, and how to get the best value.
How We're Funded, and the Conflict You Should Know About
GlassesPedia is owned and operated by the same people who run Charm Optical, an optical store in Edmonton. Some of our articles link to Charm Optical. That is a commercial interest, and you should weigh what you read here accordingly — treat product guidance as coming from a retailer, not from an independent reviewer.
What we don't do: we don't run ads, we don't use affiliate links, and we don't take payment from lens or frame manufacturers to cover their products. No brand has ever paid for a mention on this site.
We are not eye doctors. Our content is educational and should never replace professional medical advice. If you have concerns about your vision, always consult a licensed optometrist or ophthalmologist.
Our Approach
Every article on GlassesPedia follows a few principles:
- Plain language first. We avoid jargon wherever possible. When technical terms are necessary, we define them immediately.
- Evidence over opinion. Where scientific research exists, we cite it. Where it doesn't, we say so honestly rather than making claims.
- Practical and actionable. We don't just explain what something is — we help you understand what to do about it.
- Updated regularly. Lens technology and industry practices change. We update our articles to reflect current information.
Who Writes This
- Editorial. Articles are written and edited by the GlassesPedia editorial team.
- Clinical review. Where an article carries a "Reviewed by a licensed optician in Edmonton, Alberta" byline and a review date, a licensed optician on staff at Charm Optical — dispensing in Edmonton since 2017 — has read that page. Articles without that byline have not been individually reviewed.
We keep bylines role-based rather than personal, but we're strict about what they claim: on a site about vision, "reviewed by a licensed optician" has to mean a licensed optician actually read that page. We won't put that line on a page nobody reviewed.
Corrections and Contact
If you spot an error, tell us and we'll fix it and note the change. If there's an eyewear question we haven't covered, we'd like to hear that too.
