Many people who wear glasses or contact lenses can scuba dive, but the best option depends on their vision, lens type, mask fit, and medical advice. Ordinary glasses generally do not fit under a standard scuba mask, so divers often consider a prescription mask or suitable contact lenses.
Prescription dive masks
A mask with prescription lenses can provide clear vision underwater without contact lenses. Options and costs vary by prescription and mask model. Ensure the mask fits correctly and practise clearing it as taught in your course.
Contact lenses
Some divers use contact lenses under a mask, but lens type and individual eye health matter. Water exposure can increase irritation or infection risk, and a flooded mask may dislodge a lens. Ask an eye-care professional whether contact lenses are appropriate for you and follow their hygiene guidance.
What about ordinary glasses?
Regular glasses usually cannot be worn inside a standard mask because the frame interferes with the seal. Special prescription inserts or masks may be available. Avoid modifying equipment in a way that compromises the mask seal.
Safety tips
- Choose a well-fitting mask and test it before the dive.
- Practise mask clearing in a controlled setting.
- Bring an appropriate backup solution for vision needs.
- Seek advice for eye conditions or recurrent irritation.
Bottom line
Corrective vision is compatible with diving for many people, but select an option that suits your eyes and equipment. Ask an eye-care professional and a qualified dive retailer for individual guidance.
Can you wear glasses or contact lenses while scuba diving?
Ordinary glasses are not designed to be worn under a scuba mask because the arms can interfere with the seal and may press uncomfortably against the face. Many divers instead use contact lenses or a mask with prescription lenses. The best option depends on your vision needs, comfort, and advice from your eye-care professional and dive instructor.
Using contact lenses underwater
Some divers use suitable contact lenses with a well-fitting mask, but there are considerations around mask flooding, eye irritation, and hygiene. Ask your eye-care professional whether your lenses are appropriate for your activity, and follow the manufacturer’s care guidance. Practise mask clearing in training and avoid opening your eyes underwater unnecessarily.
Prescription dive masks
Prescription masks can provide a practical alternative for divers who prefer not to use contact lenses. Check whether the available lens correction meets your needs, including any difference between eyes or astigmatism. Test the mask fit before travelling and ensure it does not leak. Clear vision supports navigation and buddy awareness, so resolve vision concerns before diving rather than improvising underwater.
