Common Mistakes People Make While Buying Glasses Online in Bangladesh

Online eyewear shopping in Bangladesh has exploded in recent years — and for good reason. You get more variety, better prices, and the convenience of ordering from your phone. But buying glasses online is not the same as buying a shirt. Get it wrong and you could end up with eyewear that hurts your eyes, slips off your face, or arrives looking nothing like the product image.

At Nine Optic, we’ve spoken to hundreds of customers who came to us after a bad online glasses experience. The same mistakes keep coming up again and again. This guide will help you avoid every single one of them.

Mistake #1: Not Knowing Your Pupillary Distance (PD)

Your PD is the distance in millimetres between the centres of your pupils. It’s absolutely critical for prescription glasses — if it’s wrong by even 2–3mm, your lenses will not align properly with your eyes, causing blurry vision, eye strain, and headaches.

Many doctors in Bangladesh don’t include PD on prescriptions. You need to specifically ask for it, or measure it yourself. A simple way: use a ruler and a mirror, or ask a pharmacy to measure it for free.

Nine Optic fix: We include PD measurement as part of our free prescription review service.

Mistake #2: Ignoring Frame Size Measurements

Frames come with three numbers printed on the inside arm — lens width, bridge width, and temple length. Buying without knowing your measurements is like buying shoes without knowing your shoe size. An ill-fitting frame will slide down your nose, press your temples, and look disproportionate on your face.

Measure your current glasses’ arm if you have them. If not, use Nine Optic’s home trial service to try 5 frames at home before committing.

Mistake #3: Not Checking the Return and Exchange Policy

Many cheap online eyewear sellers in Bangladesh have no return policy at all — or they make it so complicated that it’s effectively useless. Before ordering, check: Can you return within 7 days? Is exchange free? Who pays return shipping?

Nine Optic offers a clear exchange policy. If your glasses don’t fit or you’re not satisfied, we work with you to find a solution.

Mistake #4: Choosing the Wrong Lens Type for Your Power

This is one of the most common and costly mistakes. High-power prescriptions (above ±4.00) should not be made in standard CR39 plastic — the lens will be very thick and heavy. They should be in 1.67 or 1.74 high-index material.

Meanwhile, many online sellers offer only one lens type regardless of your prescription. Always confirm that the lens material matches your power level.

Mistake #5: Falling for Fake “Blue Cut” Lenses

The Bangladesh market is flooded with fake blue cut glasses that have no actual blue light filtering. They look yellow-tinted and provide zero real protection. Real blue cut lenses have a specific coating verified by spectrophotometer testing.

At Nine Optic, we use only certified blue-cut coatings from verified manufacturers — not cheap imitations.

Mistake #6: Trusting Fake Reviews and Unknown Brands

Several online platforms in Bangladesh (Facebook pages, Instagram shops) sell eyewear with thousands of fake 5-star reviews. Common red flags: all reviews posted within a few days, no photos, no specific lens details mentioned.

Protect yourself by ordering from established brands with real customer photos, verifiable business registration, and a physical address or store you can verify.

Mistake #7: Skipping Lens Coating Options

Many people focus entirely on the frame and forget about coatings. In Bangladesh’s dusty urban environment, anti-scratch coating is essential. If you spend long hours on screens (which most office workers in Dhaka do), anti-reflection coating should be non-negotiable. UV protection is vital if you’re frequently outdoors.

Mistake #8: Not Verifying Prescription Accuracy

Using an expired prescription (over 1–2 years old in Bangladesh) is a common mistake. Your power changes over time, especially in younger people and those with progressive myopia. Wearing the wrong power strains your eyes without you realising it.

Always get a fresh eye test before ordering new glasses. Many optometrists in Dhaka and other cities charge BDT 200–500 for a basic refraction test.
