Computer Glasses vs Blue Cut vs Anti-Glare: What’s the Difference?
Ask for “computer glasses” in a Pakistani optical shop and you may be offered three different things: a blue-cut coating, an anti-glare (anti-reflective) coating, or a lens whose power is set for a screen at arm’s length. Those are not the same product. Mixing them up is how people pay for a filter they did not need — or skip the coating that would have helped under office lights.

The three labels, in plain language
Anti-glare / anti-reflective (AR) is a thin coating that reduces reflections on the front and back of the lens. Tube lights, a bright window behind you, and oncoming headlights bounce less. Photos and video calls show less white shine. This is the workhorse extra for most indoor lighting in Pakistan.
Blue cut / blue light protection is a filter or tint that removes a portion of short-wavelength visible light from screens and LEDs. It may slightly warm the look of a monitor. It does not change your prescription, and it is not sunglasses.
Computer glasses, used carefully, means lenses aimed at the intermediate distance — roughly 50–80 cm, where a laptop sits. That can be your normal distance prescription if it already works at the desk, a slightly different power written for office work, or the middle corridor of a progressive lens.
The power is the medical part. Coatings are extras on top.
| What you hear | What it actually is |
|---|---|
| Computer glasses | Power set for a screen at arm’s length |
| Blue cut | Filter for some blue-violet light |
| Anti-glare / AR | Coating that cuts reflections |
Why Pakistani shops blur the names
“Anti-glare,” “blue cut,” “computer,” and “UV” are often sold as a bundle, sometimes as if they were one coating. A bundle can be convenient. It is still worth knowing which layer you are paying for:
- If lights smear across the lens, you are describing reflections → AR.
- If you want a screen filter and a slightly less harsh white page → blue cut.
- If the laptop is clearer when you borrow someone’s reading glasses, or you keep lifting progressives to look under them → you may need a power check for intermediate distance, not another coating.
Monitor height, lighting, and breaks still matter more than any coating. See Computer and Office Eyewear.
What each one costs on Eyeglass.pk
Frame prices start from Rs 1,999. There is no separate “computer glasses” product. Choose a frame from men’s eyeglasses, women’s eyeglasses, or rimless eyeglasses, then open Select Lenses. Prices are shown there. Lenses are not a free extra on the frame.
Examples currently shown in Select Lenses (they can change — confirm on the frame you choose):
- Anti-reflective (AR) — around Rs 1,500
- Blue light protection (blue cut) — around Rs 3,000
- Bifocal — around Rs 4,000
- Progressive — around Rs 6,000
If your optometrist has written a computer-only prescription, enter those numbers as the Rx for that pair. Do not type your driving prescription into a pair meant only for the desk, or the other way round.
Which combination fits common workdays
Most single-vision wearers under office lights: current distance (or dedicated computer) prescription plus AR. Add blue cut if you also want the filter and the extra shown in Select Lenses fits the budget.
Progressive wearers at a desktop: look through the intermediate zone rather than buying another coating in hope. If the monitor zone feels tiny, the frame may be too shallow — a fit issue, explained in the progressive beginners guide.
No prescription, only want “something for the laptop”: AR and/or blue cut on non-prescription lenses are optional. They will not treat an uncorrected refractive error. If the screen is clearer when you squint, book an exam first.
Night commute: AR is the coating most clearly aimed at headlight smear. If Select Lenses also lists a night-driving extra, ask which layer you actually need rather than ticking every box.

What not to mix up with sunglasses
Blue cut is not UV protection for Karachi noon. Dark fashion tints without a stated UV rating can be worse than no sunglasses, because the pupil opens while ultraviolet still reaches the eye. For outdoor glare, use the sunglasses collection or sunglasses for driving and outdoor use. Lenses that darken in sunlight are a third path — see the photochromic price guide.
A simple order: confirm the prescription for the distance you will use; add AR if lights or night glare bother you; add blue cut only if you specifically want a screen filter.

Frequently asked questions
Is anti-glare the same as blue cut?
No. Anti-glare (AR) reduces reflections. Blue cut filters some blue-violet light. A lens can have one, both, or neither.
Do computer glasses have to be blue cut?
No. Computer glasses are about the focusing distance. Many computer pairs have no blue filter at all. Many blue-cut pairs are ordinary distance glasses.
Can I tick AR and blue cut together?
Yes. On Select Lenses they are separate extras (around Rs 1,500 and Rs 3,000; confirm, as they can change). Together they cost more than AR alone; only add both if you want both jobs done.
Will these coatings fix headaches after video calls?
Not by themselves. An uncorrected prescription, dryness from low blink rate, and screen glare are more common causes. Coatings are comfort tools, not a diagnosis.
