What is GlassesPedia?
GlassesPedia is a free, independent 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 comes from stores trying to sell you something, or from medical sources written in jargon that assumes you already know what you're reading. There's very little in between — practical, honest, 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.
What We Don't Do
We don't sell glasses. We don't have affiliate links. We don't run ads. We don't accept sponsored content. When we mention a brand or a retailer, it's because they're relevant to the topic — not because they paid us.
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.
