Many people preferred to buy glasses where they had their eyes tested, which makes sense in terms of getting personalised advice from someone who is familiar with your prescription. But our results suggest it might be a good idea to shop around.
Online retailers may also be an attractive option for the convenience and price, but make sure you read our advice below on what to do before buying glasses online.
While using different brands for buying glasses and getting your eyes tested enables you to shop around for your favourite frames, it can lead to problems if there's a dispute over an issue with glasses and who is responsible. Ask staff at your optician store how this would work.
Our expert opticians recommend the following when you're deciding where to buy your specs, and what you can afford:
We surveyed people about their experiences of shopping for prescription glasses online, and asked opticians for their advice on how to ensure you get the best from buying glasses on the web.
Just over half (46%) of those who bought online bought from Glasses Direct. The highest rated brand received 87%, with the lowest brand at 67%.

People tended to buy online for reasons of cost and convenience, and we've found that this is often a good option for people with simpler prescriptions.
73% of people shopping for glasses online bought single vision lenses, rather than varifocals. In the past, we’ve found that if you’ve got a relatively simple prescription, you shouldn’t run into too much trouble buying online.
More caution is needed if you have a complex prescription (for example, higher strength lenses or varifocals), where getting really specific measurements to make sure the frames fit and lenses are positioned correctly in front of your eyes is of paramount importance.
We’ve also found that you are less likely to get personalised information about lens thickness, frames and coatings or tints when you order online.
Here’s what you need to know if you’re thinking about ordering glasses online:
Opticians aren't required to put all the measurements needed to dispense glasses on your prescription, as some are taken when your glasses are dispensed rather than when your eyes are tested. This means that by buying online you may be missing details such as your such as your PD (pupillary distance).
The PD helps position your pupils accurately in the centre of the lenses. It’s crucial for higher prescriptions and varifocals to have your exact PD, because a measurement more than a couple of millimetres out could make the glasses unusable.
Best practice is for stores to request an exact PD from the customer – which unfortunately might not always be included on your prescription. But some stores have ways you can do this at home. Others simply let you use an average measurement, which may result in poorly fitted glasses.
Look for websites that send you a selection of frames to try at home. Also look for websites that have a ‘best fit finder’ and frame fitting advice, and that give full frame measurements. And if you need to take measurements yourself, make sure they’re accurate.
Getting the right lenses if you’ve got a high prescription you should opt for high index (thinner) lenses when buying online as they’re more likely to work with a range of frames.
As a rule of thumb, if your prescription is stronger than +/- 3 but less than +/- 5, consider thinner lenses (around 1.67 index). If your prescription is stronger than +/- 5, you may want to go even thinner (around 1.74 index).
Getting the right frames it’s not necessarily easy when shopping online to know which frames will suit your prescription (as above), or fit properly.
Some sites offer a free try-at-home service. This could be a good way to make up for the lack of in-person fitting advice, and you can take some time to decide what fit works for you.
Varifocals are the cause of many complaints to the Optical Consumer Complaints Service.
The ideal varifocal lens design provides sharp vision in the far distance, middle and close up for reading, is comfortable to swap between each zone, is easy to get used to, and has few distortions at the edges.
Varifocal design has become very sophisticated over the past 10 years, but there are big differences in quality and variability of lenses. Use our guide to to make sure you know what level you need and what quality you’re buying.
Precise fitting measurements – such as the pupillary distance (PD) and the vertical pupil position - are crucial to how well any lens will perform.
Our experts also strongly discourage shoppers from buying bifocals or varifocals from websites that don’t ask – at the very least – for additional information that would help them gain the necessary measurements, such as a photo of the customer wearing their chosen frames.
Any terms and conditions that say you must cover the cost of returning an item don't apply where the goods being returned are faulty.
When you buy goods online, you have additional rights to return them. This is because your decision may be based on a brief description or a photograph – so what you receive isn't always quite what you’d expected.
We asked more than 1,000 people who wear contact lenses about their experience buying them - both in-store and online - including quality of lenses, value for money, price and customer service.

In the UK, contact lenses can only be fitted by, or under the supervision of, a registered optometrist, qualified dispensing optician or medical practitioner.
Once fitting is completed, your practitioner will issue you with a contact lens specification. You can then buy contact lenses from a shop or go online, provided the sale is under the ‘general direction’ of a registered practitioner.
The law says that online sellers must confirm that a buyer has a valid contact lens prescription by seeing it, or checking with the optician who supplied it. Eyes change over time, and an optician can pick up on complications and worrying practices, such as inadequate cleaning, that threaten eyesight.
If you do shop for lenses online, don’t assume that prices are always lower; factor in shipping, handling and insurance costs that can bump up prices.
