Am I Blind, or Am I Just Getting Old? The Malaysian Eyesight Report
Everyone thinks their own eyes are unusually bad. Here are the numbers that settle it. We pulled every prescription submitted by 124 Malaysian customers of 100glasses, split them by race and gender, and measured exactly how myopic, astigmatic, and presbyopic the sample really is.
If you came here asking "am I blind?", the answer is almost certainly no. You're probably sitting in the fat middle of the Malaysian pack. If you came here asking "am I getting old?", keep scrolling.
The one-line answer: yes, Malaysians are myopic
- 83% of customers (103 out of 124) are myopic (SPH worse than -0.50 in at least one eye)
- 16% are high myopes (SPH of -6.00 or worse)
- 69% have clinically significant astigmatism (cylinder of 0.75 or more)
- 27% have anisometropia, meaning a difference of 1.00 dioptre or more between the two eyes
- 10% are hyperopic (farsighted, SPH of +0.50 or more)
For context, population-level myopia in Malaysian adults is usually reported around 30 to 40%. Our number is more than double that, which makes sense: people who voluntarily buy prescription glasses online are, almost by definition, people who need them badly.
How bad is your eyesight, actually?
| Category | SPH range | n | Share |
|---|---|---|---|
| Hyperopia | +0.50 and above | 13 | 10% |
| Emmetropia | -0.49 to +0.49 | 8 | 6% |
| Mild myopia | -0.50 to -2.99 | 46 | 37% |
| Moderate myopia | -3.00 to -5.99 | 38 | 31% |
| High myopia | -6.00 and beyond | 19 | 15% |
Median SPH across the sample is -2.75. The middle 50% of Malaysian prescription-wearers fall between -4.75 and -1.5. The worst case in our data was -9.5. The most hyperopic was +6.
So if your prescription is somewhere around -2.00 to -4.00, you're squarely average. Boring, even. If you're worse than -6.00, you're in the top 16% and technically a high myope, which means your retina is stretched enough that you should get it checked once a year for tears or detachment. Not to scare you, but that's the actual reason the annual exam exists.
Myopia by gender
| Gender | n | Mean SPH | Median SPH | P25 / P75 |
|---|---|---|---|---|
| Male | 48 | -2.31 | -2.25 | -4.75 / -1.5 |
| Female | 69 | -3.06 | -3 | -4.75 / -1.5 |
Malaysian women in our sample are meaningfully more myopic than men: median -3 versus -2.25. This tracks with international literature, where women tend to show slightly higher myopia prevalence and severity. The usual explanation is more near-work during education and early-career desk hours, though nobody has fully nailed down the mechanism.
Myopia by ethnicity
| Ethnicity | n | Mean SPH | Median SPH | P25 / P75 |
|---|---|---|---|---|
| Chinese | 45 | -2.44 | -3 | -4.75 / -1.25 |
| Malay | 50 | -3.45 | -3.25 | -5.25 / -1.5 |
| Indian | 6 | -3.25 | -2.25 | -4.75 / -0.75 |
| Lain-lain | 23 | -2.29 | -2.25 | -4.5 / -0.5 |
There is a surprising spread here. Malay customers have the strongest prescriptions in our sample (median -3.25), followed by Chinese (-3). Lain-lain and Indian customers cluster around the -2.25 mark.
That runs against the usual narrative that East Asians are the most myopic ethnic group globally. In our Malaysian data, the gap between Malay and Chinese is small, and the median actually tilts toward Malay severity. Big caveat: this is self-selected online buyers, not a population study, and the Indian cell (n = 6) is too small to hang anything serious on.
Ethnicity × gender
| Group | n | Median SPH | Mean SPH |
|---|---|---|---|
| Malay male | 21 | -3.25 | -3.29 |
| Malay female | 28 | -3.5 | -3.38 |
| Chinese male | 15 | -2 | -1.15 |
| Chinese female | 25 | -3 | -2.79 |
| Indian male | 3 | -2.25 | -1.92 |
| Indian female | 3 | -3.5 | -4.58 |
| Lain-lain male | 9 | -2.25 | -2.08 |
| Lain-lain female | 13 | -2 | -2.52 |
Cells with n below 5 (Indian male and female) are directional only.
Astigmatism, anisometropia, and other supporting characters
Astigmatism clocks in at 69%. More than two in three of our customers have at least 0.75 dioptres of cylinder, which is the threshold at which you start to notice real blur. That sounds like a lot until you remember most people have some corneal asymmetry. Ordering glasses just surfaces it.
Anisometropia is 27%, so roughly one in four customers has eyes that differ by a dioptre or more. If that's you, skip the ready-made "one power for both eyes" bin glasses. They'll never correct both eyes properly and you'll end up with a headache you can't place.
Hyperopia is the minority at 10%. About 1 in 10 customers has a positive prescription, mostly mild (+0.50 to +2.00).
Part 2: Am I getting old?
You know that slightly insulting moment when the menu starts to blur and you catch yourself holding it a bit further away? That's presbyopia. It's the age-related loss of the eye's ability to focus up close, and it typically shows up somewhere in the mid-40s. The fix is an ADD power (added reading power) stacked on top of your distance prescription, usually via a progressive or multifocal lens.
What share of our customers are correcting presbyopia?
| Vision type | Orders | Share |
|---|---|---|
| Single Vision (distance only) | 111 | 90% |
| Progressive (smooth distance-to-near) | 6 | 5% |
| Multifocal (segmented distance-to-near) | 1 | 1% |
Combined progressive + multifocal orders account for 6% of the sample. That's a lower bound on presbyopia in our customer base — plenty of 45+ adults still buy single-vision distance glasses and cheat with a pair of drugstore readers at home.
Among the 8 customers who submitted an ADD power, the mean was +1.72 (median +1.5), ranging from +1 to +3.25. This is consistent with the typical presbyopic progression: around +1.00 at age 45, +1.75 at 55, +2.50 by 65.
So — are you getting old? If you're starting to need an ADD of +1.00 to +1.50, you're in early presbyopia, which usually arrives in the mid-40s. Welcome to the club.
What to do about it
- If your SPH is worse than -6.00, book an annual dilated eye exam. High myopes have a higher lifetime risk of retinal detachment, glaucoma, and myopic macular degeneration.
- If you're over 40 and menus are blurring, you need progressive or multifocal lenses, not a stronger single-vision prescription. See our how it works guide — we carry both.
- If one eye differs by more than a dioptre from the other, custom prescription lenses (what we sell) are the only way to correct both comfortably. Generic readers won't cut it.
- If your cylinder is 0.75 or higher, you have astigmatism. The fix is the same: prescription lenses, ground to your specific axis.
Our entry prescription frames start from RM49 with free premium 4-in-1 lenses. If you're squinting at your phone more than you used to, it's cheap to fix. Browse the catalogue or run the style quiz to narrow down.
Methodology
Sample. 124 unique Malaysian 100glasses customers. If a customer ordered multiple times, only their latest prescription is counted. Test entries, blank names, and orders with no SPH were excluded.
SPH. For each customer we report the worst eye (largest absolute value). This is the standard convention for summarising severity and is more meaningful than a simple OD/OS split.
Myopia categories. Follow the conventions widely used in optometry literature: mild (-0.50 to -2.99), moderate (-3.00 to -5.99), high (-6.00 or worse).
Astigmatism. Flagged if either eye had a cylinder of 0.75 D or higher (the threshold at which correction is typically recommended).
Anisometropia. Difference of at least 1.00 D between the two eyes' SPH values.
Ethnicity and gender. Inferred from customer names by a large language model using Malaysian naming conventions. See the companion PD study for the full classifier methodology.
Caveats
- Sample is self-selected: customers who ordered prescription eyewear online.
- Age is not recorded, so presbyopia prevalence is under-counted because the sample likely skews under 40.
- A small number of zero-power orders (plano sunglasses or blue-light frames) were excluded from SPH stats.
- ADD values are only reported for multifocal/progressive orders (n = 8).
