Wearing contact lenses at high altitudes, such as those found in Nepal (3000-4000 meters above sea level), can present some challenges, particularly due to the dry and thin air conditions. Here are several considerations and recommendations based on your situation:
1. Dryness and Oxygen Levels: At high altitudes, the air is significantly drier, which can lead to increased evaporation of moisture from your eyes. This can cause discomfort, dryness, and irritation when wearing contact lenses. Additionally, the lower oxygen levels at high altitudes can affect your overall eye health and comfort.

2. Type of Contact Lenses: Since you are using daily disposable soft contact lenses, this is generally a good choice for travel. Daily disposables can help reduce the risk of infection and are convenient since you can discard them at the end of the day. However, you should ensure that your lenses are designed to retain moisture, as this will be crucial in a dry environment.

3. Use of Rewetting Drops: Carrying a good quality rewetting drop is essential. Make sure the drops are compatible with your contact lenses. Using these drops can help alleviate dryness and keep your lenses comfortable throughout the day. It’s advisable to use them more frequently at high altitudes.

4. Limit Wearing Time: You mentioned that you typically wear your lenses for no more than 7 hours a day. This is a prudent approach, especially in high-altitude conditions. If you start to feel discomfort or dryness, consider reducing the wearing time further or switching to glasses when possible.

5. Backup Plan: Always have a backup plan in case your lenses become uncomfortable. Bring a pair of glasses with you as an alternative. This is particularly important if you experience any adverse reactions or if your lenses dry out too much.

6. Hydration: Staying well-hydrated is crucial when traveling to high altitudes. Dehydration can exacerbate dryness in your eyes. Make sure to drink plenty of water throughout the day.

7. Consult Your Eye Care Professional: Before your trip, it’s wise to consult with your eye care professional. They can provide personalized advice based on your specific eye health and the type of lenses you use. They may also recommend specific brands of lenses or eye drops that are better suited for high-altitude conditions.

8. Monitor Your Eyes: Pay attention to how your eyes feel during your trip. If you experience significant discomfort, redness, or vision changes, it’s important to remove your lenses and switch to glasses. Prolonged discomfort can lead to more serious issues, such as corneal abrasions or infections.

In summary, while you can wear contact lenses at high altitudes, it requires careful management of dryness and comfort. By following these recommendations and being prepared with the right supplies, you can help ensure a more comfortable experience during your travels in Nepal. Safe travels, and enjoy your adventure!
