The DMD goggle for eye comfort and protection. They can be worn over ordinary glasses and have a universal fit. The DMD goggles are anti-scratch and exclusively designed for DMD. They are available in clear, smoke, orange, yellow and light smoke. All the shields are very strong and durable, but they can get damaged. Take care not to expose your shield to any chemicals. Visor cleaning should be done only with warm water, mild soap and a micro fiber cloth.
