When travelling this summer, contact lens users should carefully consider their eye care routines, particularly during flights. While many might prefer to wear contact lenses instead of glasses, this choice can lead to discomfort and potential complications.
Dr. Priya M. Mathews, an expert in ocular surface diseases, notes that wearing contacts is generally acceptable on short flights, provided the eyes are healthy and the traveller does not intend to sleep during the journey. For longer flights, however, the dry cabin environment can cause significant issues for contact lens wearers. The air inside an aircraft is often quite arid, which may lead to dryness, irritation, and increased sensitivity of the eyes.
Mathews warns that prolonged exposure to dry cabin air can result in uncomfortable sensations, such as grittiness or pain. Furthermore, the pressurised environment at high altitudes reduces oxygen availability to the eyes, exacerbating these effects. In severe cases, the lenses might adhere to the eye’s surface, potentially causing micro-tears and increased likelihood of infection.
Dr. Arjan Hura, a cataract and eye surgeon, highlights the heightened risk of eye infections associated with sleeping while wearing contact lenses, emphasising that anyone experiencing redness, irritation, or existing infections should opt for glasses instead.
For those determined to wear contacts, maintaining hygiene is crucial. Washing hands before handling lenses and ensuring access to adequate lens solution is essential in preventing infections. Hura advises regular lens replacement, the application of artificial tears, and suggests carrying a backup pair of glasses for emergencies, especially during extended travel.
Lastly, travellers need not worry about transferring contact lens solution to compliant containers, as travel-sized options are readily available.
