Swimming or diving in low-light conditions—such as at night or in murky waters—often requires external light sources like waterproof torches, which can be cumbersome and restrict movement. One way to address this could be with swimming goggles that have built-in illumination, offering hands-free visibility without sacrificing comfort or mobility.

How It Could Work

The goggles could integrate lighting in two ways: active LEDs with adjustable brightness or a hybrid system combining passive light-amplifying lenses with minimal active lighting. A small, waterproof rechargeable battery (similar to those in action cameras) could power the LEDs, lasting 2–4 hours per charge. To ensure durability, waterproofing techniques like sealed compartments and gaskets could be used, tested to IPX8 standards. Additional features might include anti-fog coatings, UV protection, and a customizable fit.

Who Could Benefit

• Recreational swimmers who enjoy night swimming in open water or dimly lit pools.
• Professional divers working in low-visibility environments, such as researchers or underwater photographers.
• Rescue teams conducting search operations in murky or nighttime conditions.

Potential Advantages Over Existing Solutions

Unlike clip-on dive lights or handheld torches, integrated lighting would eliminate the need for external accessories, improving mobility. Compared to standard low-light goggles (which rely on tinted lenses), active illumination would work in total darkness. Adjustable brightness and diffused lighting angles could also reduce glare in murky water, while hybrid models might include polarized lenses for better clarity.

To test feasibility, a minimal prototype—such as a clip-on LED attachment for existing goggles—could gauge user interest before refining the design for weight, battery life, and light diffusion. Premium models could target professional divers, while simpler versions cater to casual swimmers.
