What are Computer Glasses?
Contents
Computer glasses is an umbrella term for glasses made for screen work. No single lens defines them. Depending on your eyes, they might be prescription lenses set for screen distance, or non-prescription lenses with an anti-reflective coating. Either can come with an optional blue-light filter.
What they share is the working distance. A monitor sits further away than a book and closer than a road sign, so lenses made for reading or for driving can leave your eyes working harder at a desk. Computer glasses match the lens to how far away you actually look, and to your own prescription. The blue-light filter is the least important part of that.
At SmartBuyGlasses, our prescription computer glasses are occupational lenses, also called computer varifocals or office lenses. They cover near and intermediate distances, so your keyboard, documents and monitor all stay in focus. A blue-light filter can be added, but it’s optional.
Occupational lenses are also known as office lenses. If you want to go deeper on choosing the right working distances for your particular desk setup, our guide to computer lenses covers that in more detail.
Computer lenses vs single vision vs reading vs varifocals
Lens type | Working distance | Zones of focus | Best for | Limitations |
Single vision (distance) | Far: the road, across a room | Distance only | Seeing things far away | A screen can look blurry if you need help up close |
Single vision (reading) | Near: a book or phone held close | Near only | Reading and other close work | Set for a closer distance than most monitors, so a screen at arm’s length can look blurry |
Occupational (computer varifocal) | Near and intermediate: keyboard, documents, monitor. Our lab sets the lens power for an 80cm working range, based on your ADD value. | Near and intermediate | Working at a computer and seeing at arm’s-length distances | Not for driving or all-day wear, and can feel over-strong for a phone held close |
Varifocal (everyday) | Near, intermediate and distance | All three | One pair for close, far and in between | The intermediate band can feel narrow at a desk |
Our guide to occupational lenses and working distances goes into more detail on measuring your setup and choosing between lenses. This page covers whether you need computer glasses at all.
Are computer glasses the same as reading glasses?
No. Reading glasses are single-vision lenses set for close reading, so a monitor at arm’s length can look blurry through them. Occupational lenses are set for your working distance instead.
Who might benefit from computer glasses?
You might be a good candidate for computer glasses if some of this sounds familiar: a large part of your day is spent looking at a screen, and by the afternoon your eyes feel tired, your vision blurs slightly, or you’ve picked up a dull ache across your neck and shoulders. Headaches and dry or red eyes after a long day at the computer are also worth paying attention to.
Your existing prescription matters too. If you already wear varifocals and find the intermediate band too narrow at your desk, or your prescription includes an ADD (the extra power for close-up vision) value used for near or varifocal correction, that’s worth raising with your optician when you ask about computer glasses. And because focusing between near and mid-range distances tends to get harder with age, it’s a conversation many people find useful to have earlier rather than later.
None of this is a checklist. Everyone’s eyes and workload are different, so if these symptoms keep coming back, book an eye exam and ask your optician about your screen distance rather than guessing on your own.
Do computer glasses actually work?
The anti-reflective coating and the near-and-intermediate lens design do a provable job: less glare, and a lens matched to your actual working distance rather than borrowed from reading or driving glasses.
A Cochrane review found that blue-light filtering lenses may not reduce short-term computer-related eye strain, and any benefit for sleep remains uncertain. If you want a filter, treat it as an optional extra, not the reason to buy.
What each part of the lens is actually doing
Lens element | What it does | What it doesn’t do |
Lens design (near + intermediate) | Corrects your vision at screen and keyboard distance, if that’s where your eyes need help | Won’t do anything if your eyes don’t actually need correction at that distance |
Prescription correction | Corrects your own vision at your working distance | A distance prescription doesn’t automatically work at screen distance, so you need an up-to-date eye exam |
Anti-reflective coating | Cuts down glare and reflections bouncing off the lens surface | Doesn’t reduce the amount of light coming from the screen itself |
Optional blue-light filter | Reduces the amount of blue light reaching your eyes | Doesn’t protect the eyes from UV light outdoors |
Because dual focus/occupational lenses are built for near-and-intermediate distance, they’re not the right choice for driving or all-day wear away from your desk, and they can feel over-strong for a phone held close to your face. For all-day, multiple-distance use, a varifocal is usually the better fit (see the comparison above).
If you’re dealing with computer vision syndrome, also called digital eye strain (headaches, dry eyes, blurred vision), our article on digital eye strain covers causes and relief in more depth.
Are computer glasses and blue light glasses the same thing?
Not quite. Blue light glasses have a coating or tint that reduces blue light reaching your eyes, and it can be added to prescription or non-prescription lenses. It’s one possible feature of computer glasses, not what defines them.
Occupational lenses add the near-and-intermediate design covered above, and are often combined with an anti-reflective coating to cut screen glare.
Do you need a prescription for computer glasses?
It depends what you want the lenses to do. For occupational lenses, you don’t need a full prescription. You only need your ADD value, the extra power for close and intermediate distances. An up-to-date eye exam is the reliable way to get it. If you see your screen comfortably, you can still add an anti-reflective coating or a blue-light filter to non-prescription lenses, but they won’t correct your vision.
Lens option | Prescription needed? | What it does | Good to know |
Occupational (near and intermediate) | No, ADD value only | Corrects vision at screen and keyboard distance | Not for driving or all-day wear |
Non-prescription with anti-reflective coating | No | Cuts glare and reflections from the lens surface | Doesn’t correct vision |
Optional blue-light filter | No, can be added to either | Reduces blue light reaching your eyes | Limited evidence for reducing eye strain |
How to choose computer glasses
Start with a measurement, not a guess. Sit at your usual spot and measure the distance from your eyes to your monitor, most desk setups land somewhere around 50-70cm, though it’s worth checking your own rather than assuming. You won’t need to enter this distance when you order from us, but it helps your optician understand your setup.
Do the same for anything else you look at often at a closer range: a notebook, printed pages, a second screen. That’s the actual information an optician needs, not a one-size figure.
From there, the route depends on where you’re starting from:
- No glasses currently: book an eye exam to check whether you need correction at all, and ask whether an ADD value would help at your desk. For occupational lenses, that’s all you need to order.
- Existing distance prescription: mention your working distance to your optician. A prescription ground for distance vision doesn’t automatically translate to screen distance, and an intermediate ADD can help here, though it isn’t something everyone needs. You don’t need to give us a working distance when you order.
- Managing presbyopia: a dedicated pair for desk work can sit alongside your varifocals, so it’s worth discussing if you’re finding the intermediate band too narrow at your monitor.
- At checkout: pick your frames first, select the Occupational lens type, and enter your ADD value. There’s no working distance to enter, because our lab calculates the lens power for an 80cm working range from your ADD value. A blue-light filter and an anti-reflective coating are both optional add-ons from there, worth choosing based on your own setup rather than adding by default.
Comfort beyond the glasses
The right lenses help, but they’re not the whole story. A few habits make a real difference alongside them: take a proper break from your screen every so often, blink more than you think you need to (screen focus quietly cuts your blink rate), bump up your font size rather than leaning in, reduce glare from windows and overhead lights, and get your screen positioned so you’re looking slightly downward rather than straight ahead or up.
The 20-20-20 rule is a simple one to build in: every 20 minutes, look at something roughly 20 feet away for 20 seconds. It gives your eye muscles a genuine rest, rather than just a change of scenery.
None of this replaces a proper eye exam if your symptoms persist. And if it’s the broader picture of digital eye strain you’re after, including causes, lighting, screen setup, our digital eye strain guide goes further than we can here.
Getting the right computer glasses comes down to matching the lens to how you actually work, not chasing every feature at once. Measure your setup, be honest about your symptoms, and let your optician steer the specifics from there. If anything here raises more questions, speak to one of our dispensing opticians; they’re happy to help you land on the right fit for your desk.
