What Happens at an Eye Test: A Glasgow Optometrist Walks You Through All Forty Minutes

Searching “opticians Glasgow” returns a list of businesses that all look broadly similar. Same services, same reassuring language, similar photographs of frames on shelves. There is no obvious basis on which to choose, so most people pick on convenience, price, or whichever name they already recognise.
Those are not unreasonable criteria. But there are real differences underneath, and they are not the ones the websites tend to lead with. This is an attempt to set out what actually varies, written by one of the practices you would be choosing between, so read it with that in mind.
Worth saying first, because it saves worrying about the wrong things.
Every registered optician in Glasgow works to the same professional standards, is regulated by the General Optical Council, and will measure your prescription competently. Reputable practices all use equipment that is fit for purpose. If your only requirement is an accurate prescription and a pair of glasses, you will get that almost anywhere, and the differences below may not matter much to you.
They start to matter when something is going on that takes time to find.
How long is the appointment?
It is the most revealing question available and it is almost never asked. Appointment length determines what can realistically be done: how much history is taken, how thoroughly the eye is examined, whether binocular vision is properly assessed, and how much time exists to explain what was found.
Twenty minutes and forty minutes are different appointments doing different amounts of work. Neither is dishonest. But if you are being seen for twenty minutes, some things are being prioritised over others, and it is reasonable to know that before you book. Our own position on this is set out in our philosophy; we run forty minutes and call it Slow Optometry, which is a slightly grand name for simply not rushing.
We are an independent practice, so treat this section sceptically. We have tried to write the version we would want to read.
We have written a longer version of this comparison in independent opticians vs Specsavers, which tries to be fair to both.
An OCT scan images beneath the surface of the retina rather than photographing across it, which allows changes to be seen earlier than they would otherwise appear. It is genuinely useful, particularly for conditions that develop slowly and silently.
Two questions rather than one: does the practice have it, and is it included in the examination or charged as an upgrade? Both are legitimate business models, but an advertised price that excludes the scan is not comparable with one that includes it. Our page on OCT eye scans explains what it shows.
The qualification that lets an optometrist assess, diagnose and prescribe medication for eye conditions directly, rather than referring you to a GP for the prescription.
It matters on the day something goes wrong. Without it, the sequence is: see the optometrist, be told you need medication, ring the GP, wait, explain it again to someone without slit lamp access, start treatment days later. With it, you are treated in the appointment. For an inflammatory or infective condition, that gap is not merely inconvenient. It is why we handle emergency eye care in practice.
Question to ask | Why it matters | A good answer sounds like |
|---|---|---|
How long is the appointment? | Determines how much can actually be checked | “Forty minutes with the optometrist” |
Who will I see, and next time? | Continuity changes what gets noticed over years | “The same optometrist each visit” |
Do you do OCT scanning? | Sees beneath the retinal surface, not just across it | “Yes, included in the examination” |
Is it included or extra? | Add-on pricing hides the real cost | “Included, not an upgrade” |
Can you treat, or only refer? | IP-qualified practices prescribe on site | “We hold Independent Prescribing” |
What if something goes wrong? | Emergency access matters more than people expect | “Ring us the same day” |
Am I obliged to buy glasses here? | You are not, anywhere | “No, the prescription is yours” |
You are entitled to ask all of these on the phone, of any practice, before booking. A practice that finds the questions awkward has told you something useful.
These get used interchangeably and are not the same. Briefly: an optometrist examines eyes, detects abnormalities and prescribes; a dispensing optician fits and supplies glasses; an ophthalmologist is a medical doctor specialising in eye surgery and disease. Knowing which one you are speaking to is more useful than it sounds, and we cover it properly in optician, optometrist or ophthalmologist.
Something, but read them for pattern rather than sentiment. Individual reviews describe individual days. What is worth looking for is whether people mention feeling unhurried, whether the same staff names recur over years, and whether anything clinical was actually found and explained. “Lovely staff” is pleasant and tells you little. “Explained what the scan showed” tells you more. Ours are on our reviews page, for whatever that is worth coming from us.
For completeness, since you would be choosing between us and others. We are an independent, family-run practice at Bellahouston in the Southside, running forty-minute appointments with OCT included, with optometrists holding Independent Prescribing and over twenty years of experience, and consultations available in English, Urdu and Punjabi.
We are not the cheapest and we are not open seven days. If you want a fast, inexpensive spare pair, a chain will serve you better and we would say so. If you want the appointment to be unhurried and to see the same person each time, that is what we are built for. More on that on our why choose us page.

Ask how long the appointment is, who you will see and whether it is the same person next time, whether OCT scanning is included or charged extra, and whether the practice can treat eye conditions or only refer them. Those four questions separate practices far more effectively than comparing websites, and you can ask all of them on the phone before booking.
Neither is universally better. Chains generally offer broader opening hours, more branches and lower prices on entry-level packages. Independents typically offer longer appointments, continuity with the same optometrist, more curated frames and sometimes additional clinical qualifications. The right answer depends on whether you value convenience and price or time and continuity.
It varies by practice, commonly between twenty and forty minutes. Appointment length determines how much history can be taken, how thoroughly the eye can be examined, whether binocular vision is properly assessed and how much time exists to explain findings. It is the most revealing question you can ask and almost nobody asks it.
An optometrist examines eyes, detects abnormalities and prescribes corrections. A dispensing optician fits and supplies glasses and contact lenses. An ophthalmologist is a medical doctor specialising in eye disease and surgery. When you book an eye examination, the person testing your eyes is an optometrist.
OCT imaging looks beneath the surface of the retina rather than photographing across it, which allows some changes to be detected earlier than they otherwise would be. It is particularly useful for conditions that develop slowly and without symptoms. Ask whether a practice includes it in the examination or charges it as an upgrade, since that materially affects price comparison.
An optometrist who holds an additional qualification allowing them to assess, diagnose and prescribe medication for eye conditions directly, rather than referring you to a GP for the prescription. It matters most when something acute goes wrong, because treatment can begin in the appointment rather than days later
Yes, always. Your prescription belongs to you. You are entitled to be given it, and you can buy glasses wherever you like or buy nothing at all. No practice can withhold it or make you purchase from them as a condition of the test.
