Licensing: who is actually allowed to test your eyes at home
Eye testing in the UAE is a regulated clinical activity. Practitioners must hold a licence from the relevant health authority — DHA in Dubai, the Department of Health in Abu Dhabi, and MOHAP across Sharjah and the Northern Emirates — and home healthcare providers need appropriate authorisation to deliver services at your address rather than in a facility. This is not bureaucratic trivia; it is the difference between a clinical measurement you can act on and a guess from someone with a lens kit.
Verification takes two minutes and costs nothing: ask for the practitioner's licence number and issuing authority before the visit, and expect the answer without hesitation. Vendors listed on tamam are verified before they appear in the app, which handles the first filter, but there is no harm in asking again at the door. An unlicensed test is not a bargain at any price — a wrong prescription means headaches, wasted glasses, and in the worst case a missed sign of something that needed a doctor.
