Wearing Contact Lenses While Diving

Many divers wear contact lenses without issue during their dives. It’s crucial, however, to be aware of potential challenges, such as increased dryness or irritation due to factors like dry air in the dive mask, prolonged wear, mask squeezes, or exposure to saltwater. Maintaining good hygiene practices, including thorough handwashing before handling lenses and avoiding contamination, is essential.

Diving After a Stroke

Carefully weigh your return to diving, and assess the risk versus reward. No studies are available that address if the areas of your brain damaged by your stroke will be more susceptible to decompression illness. If you decide to dive, seek a detailed ongoing assessment and approval from your physician. This process should include a neurological evaluation that includes the strength and weakness of major muscle groups and the degree of cerebral injury as well as an assessment and comparison of the left side and right side of your body.
