Where people overpay on home eye tests
The most common overpayment is buying a comprehensive package when a basic refraction would do. If you are 32, healthy, and your glasses feel slightly weak, you need a prescription update — an AED 150–300 job — not the full screening tier. The reverse is also true and costlier long-term: parents of a child squinting at the whiteboard, or adult children of a diabetic parent, sometimes buy the cheapest possible test when their situation specifically calls for the fuller work-up.
The second leak is the bundled-glasses upsell. Some low headline prices are effectively subsidised by the expectation that you will buy frames and lenses from the same provider at uncompetitive prices. There is nothing wrong with buying from the tester if the price is fair, but insist on a written, portable prescription first — it is yours, and any optical shop in the UAE must be able to fill it. The third leak is paying multiple call-outs for one household: almost every provider offers a reduced per-person rate, typically AED 80–200 for each additional family member tested in the same visit, and people routinely fail to ask.
