What about contact lenses / dust in Morocco?

I wear lenses myself on trips, so this is hard-won advice: dust is the genuine challenge for contact-lens wearers in Morocco, and it is worth planning for rather than discovering the hard way. The unsealed pistes, the open desert, the gorge roads and any breezy day kick up fine, gritty dust that gets everywhere, and a speck of sand trapped under a lens is not just uncomfortable — it can scratch the eye. The dunes are the worst of it, where a gust can fill the air with sand in seconds, and that is precisely the iconic moment you most want to enjoy.

My strongest recommendation is simple: bring your glasses, and do not leave them at home because you "always wear lenses." For camel treks, dune walks, quad biking, long off-road drives and windy days, glasses are far more comfortable and far safer than lenses, and they double as a backup if your eyes have had enough of contacts. Plenty of guests switch to glasses entirely for the desert leg and go back to lenses in the cities. Prescription sunglasses are a brilliant single solution for the bright, dusty south.

If you do wear lenses, lean toward daily disposables for this trip even if you normally use monthlies. A fresh, sterile pair each day means that when one gets gritty and irritated you simply bin it rather than fighting to clean a reusable lens with limited water and questionable hygiene on the road. Pack more than you think you will need, plus rewetting/lubricating eye drops to flush out grit through the day, a spare case, and your solution in carry-on (you cannot reliably buy your exact brand locally). Wash and dry your hands properly before touching lenses, which is not always easy out in the field.

Round it off with good wraparound or close-fitting sunglasses worn whenever you are outdoors — they cut the dust reaching your eyes as much as the glare, and the two problems travel together here. If a lens does trap sand, do not rub; take it out, rinse your eye with clean water or drops, and switch to glasses for a while. Pack your eye kit — lenses, glasses, drops, solution, case — before you fly, and keep it in your day bag rather than the hold so it is with you for the dusty stretches.
