We developed the world's first technology (film insert technology) to fuse film and polycarbonate together for integrated molding.
 
These sports glasses, featuring ultra-lightweight lenses that are approximately 10 times stronger than glass in terms of impact resistance, and employ highly abrasion-resistant, optically superior, distortion-free, high-precision lenses, are offered under the 'SWANS' brand for specialized use in fishing, golf, baseball, marathons, and other sports, along with ski and swimming goggles.
 
In addition to dustproof and light-blocking glasses, the company utilizes its manufacturing technology for plastic filters that control the wavelength of light to produce various laser filters, boasting a product lineup and technological capabilities that are among the best in the world.
 
In addition to eye protection, we also develop a wide range of respiratory protective equipment, from simple masks to dust and gas masks and powered air-purifying respirators, all under the "YAMAMOTO" brand.

The number of people who haven't had an unpleasant experience due to cloudy weather at a snow resort is practically zero.
 
The relationship between goggles and fogging is a long-running and complex issue.
 
SWANS has taken this problem seriously and developed the TBR system as one of its solutions. This system has a miniature electric fan installed inside the shell at the top of the frame that cuts off the intrusion of snow water, and it can efficiently ventilate the moisture that causes fogging inside the frame with a one-touch switch that is easy to operate even while wearing gloves.
 
Furthermore, fresh outside air can be drawn in through a large air intake located on the front of the frame to replace the moisture expelled by the fan.
 
The world's only, one-of-a-kind product equipped with an electric fan.
Winner of the Good Design Award.

Swans sports glasses use polycarbonate lenses that have approximately 10 times the impact resistance of the glass used in space helmets. Their performance remains unchanged even in harsh temperature environments ranging from low to high temperatures. Furthermore, thanks to a world-first technology that fuses and integrally molds the lenses with a film, they are ultra-lightweight yet highly impact-resistant, scratch-resistant, optically superior, distortion-free, and high-precision lenses.
 
FUNCTION
• Blocks 99.9% of ultraviolet rays (UVA, UVB, and UVC).
• Polarized lenses reduce glare caused by the scattering of light rays.
• The water-repellent function instantly repels water droplets, ensuring clear vision even in bad weather or when sweating.
• The spherical curved lens conforms to the shape of the face, eliminating wind resistance and preventing wind from entering the lens, and preventing light from entering from the sides.

For protection against droplet infection! "MADE in JAPAN" eyeglass-type face shield glasses

We need products that are "non-slip," "lightweight," and "easy to wear" for people working in healthcare and manufacturing!

2) Anti-fog "Shield Lens": Lenses are less likely to fog up even when wearing a mask!
3) Flexible frame that fits any face width: A perfect fit for a wide range of people, from women to men!
4) One-touch replaceable shield lens: Simply lift the fastener to easily replace the shield!

Infection control and dust control

This non-ventilated model can be used with large eyeglasses!
 
1) Non-porous type: The frame has no ventilation holes, preventing infection and the intrusion of fine dust and other particles from the outside.
2) Can be used with large glasses: Can be worn over your existing large glasses.
3) Choose from two types of lenses!
① PET-AF (Double-sided hard coating & anti-fog)
② AP (Outer hard coat + Inner anti-fog)
