Blue light glasses vs anti-glare — these two lens coatings are the most commonly confused options at Pakistani optical shops. Both reduce eye strain from screens, but they work through completely different mechanisms. Blue-cut lenses filter blue light wavelengths emitted by screens. Anti-reflective (AR) lenses eliminate reflections from the lens surfaces. Many people need both — and at Chashmaywaly, you can get the combination from PKR 3,000.
Side-by-Side Comparison
| Feature | Blue Light (Blue-Cut) | Anti-Glare (Anti-Reflective) |
|---|---|---|
| What it does | Filters 30–40% of blue light (400–450nm wavelength) | Eliminates light reflections from lens surfaces |
| Helps with | Digital eye strain, sleep disruption from screens | Glare from overhead lights, monitor reflections, night driving halos |
| Visual appearance | Slight yellow tint; blue-purple reflection on surface | Lenses look clearer and more transparent; green/purple reflection |
| Price (PKR) | 1,500 – 3,000 (non-prescription); add PKR 500–1,000 to prescription | 2,000 – 4,000 (non-prescription); add PKR 500–1,500 to prescription |
| Best for | Screen-heavy workers, gamers, evening device users | All glasses wearers, especially in fluorescent-lit offices |
| Night driving benefit | Minimal | Significant — reduces headlight halos and streetlight glare |
How Blue Light Filtering Works
Screens (phones, laptops, monitors, TVs) emit blue light in the 400–490nm wavelength range. Blue-cut coatings contain a pigment that absorbs or reflects a portion of this blue spectrum — typically 30–40% of the highest-energy blue (400–450nm). The remaining blue light passes through normally.
The benefits are most noticeable for:
- People who work 6+ hours on screens daily
- Evening screen users — blue light suppresses melatonin (sleep hormone) production. Filtering it helps your body prepare for sleep.
- People in fluorescent-lit environments — tube lights emit significant blue light
How Anti-Reflective Coating Works
Standard lenses reflect 8–12% of incoming light. These reflections cause:
- Distracting ghost images on the lens surface
- Halos around lights (especially noticeable at night)
- Reduced clarity — less light reaches your eyes
- Visible reflections on video calls — colleagues see light bouncing off your lenses instead of your eyes
AR coatings use multiple thin layers of metal oxides that destructively interfere with reflected light waves, reducing reflections to under 1%. The result: clearer vision, better eye contact in person and on camera, and reduced strain from overhead office lighting.
Do You Need One or Both?
| Your Situation | Recommendation |
|---|---|
| Heavy screen user (6+ hours), office worker | Both — maximum screen comfort |
| Light screen use, mainly outdoor | AR only — reduces indoor/night glare |
| Night driver who wears glasses | AR only — reduces headlight halos |
| Student studying on laptop + books | Both — protects during screen study, AR helps under tube lights |
| Gaming enthusiast | Blue-cut — primary concern is screen blue light |
| Photographer / video call professional | AR priority — eliminates lens reflections in photos and video |
Combination Lenses at Chashmaywaly
The best value option is a combination lens that includes both blue-cut filtering and anti-reflective coating. At Chashmaywaly:
- Non-prescription blue-cut + AR: PKR 2,000 – 3,500
- Prescription blue-cut + AR: PKR 3,000 – 5,000
These combination lenses are available with any frame in the eyeglasses collection.

Frequently Asked Questions
Are blue light glasses the same as anti-glare glasses?
No. Blue light glasses filter blue wavelengths from screens. Anti-glare glasses reduce surface reflections. They solve different problems and work best together.
Can I get both blue-cut and anti-reflective on the same lens?
Yes. Combination lenses with both coatings are available at Chashmaywaly from PKR 2,000 (non-prescription) or PKR 3,000 (prescription). This is the recommended option for office workers.
Do blue light glasses have a yellow tint?
A very slight yellowish tint is normal — it's the blue light being filtered. Quality blue-cut coatings minimise this tint so it's barely noticeable. You'll also see a slight blue-purple reflection on the lens surface, which is the coating working.
