Buying prescription glasses online has become increasingly popular in the UK, offering convenience, choice, and often better value. But for many people, it still feels risky — will they fit properly, will the lenses be right, and what happens if something goes wrong?
The good news is that buying glasses online can be safe, accurate, and straightforward when you know what to look for. This guide explains how to choose prescription glasses online with confidence — and avoid the most common (and costly) mistakes.
1. Start with a Valid, Up-to-Date Prescription
Your prescription is the foundation of your glasses. In the UK, eye tests are typically valid for two years (or one year for children).
Before ordering online, make sure your prescription includes:
- Sphere (SPH)
- Cylinder (CYL) and Axis (if you have astigmatism)
- Add power (for varifocals or reading lenses)
- Pupillary Distance (PD) — if available
If your PD isn’t listed, you can ask your optician to provide it. You can also learn more about UK prescription standards from the College of Optometrists.
2. Choose Frames That Suit Your Face — Not Just Trends
One of the biggest mistakes when buying glasses online is choosing frames based purely on fashion rather than fit.
Key things to check:
- Frame width — should sit comfortably without pinching or slipping
- Bridge size — especially important for comfort and lens positioning
- Lens height — crucial for varifocal and progressive lenses
At Burghley & Co, our curated collections make this easier:
3. Understand Your Lens Options (This Matters More Than the Frame)
Lenses have a bigger impact on comfort and vision than most people realise. Choosing the wrong lens type can lead to eyestrain, distortion, or dissatisfaction — even if the frame is perfect.
Common lens options include:
- Single vision lenses
- Varifocal (progressive) lenses
- Blue light filtering lenses
- Anti-reflection and scratch-resistant coatings
If you’re unsure which lenses are right for your lifestyle or prescription, professional guidance makes all the difference. As a registered dispensing optician, I personally support customers with lens and prescription queries to ensure accuracy and comfort.

4. Be Cautious with Extremely Cheap Glasses
While budget options exist, unusually low prices can sometimes mean compromises in lens quality, coatings, or frame durability.
Reputable retailers should clearly explain:
- Where frames are sourced
- What lens materials are used
- Who handles glazing and quality control
For independent guidance on eyewear quality and safety, organisations such as Which? provide helpful consumer insights.
5. Know What Support Is Available If You Need Help
One concern many people have about buying glasses online is the lack of human support. This doesn’t have to be the case.
At Burghley & Co, support doesn’t end at checkout. If you have questions about:
- Prescription details
- Lens suitability
- Frame fit concerns
- Adjustments or aftercare
You can speak directly with me for personalised guidance. This ensures your glasses are right for your vision — not just your basket.
