A multi-thickness lens for a goggle may be disclosed in accordance with various embodiments. The multi-thickness lens may include a portion of a first thickness and a portion of a second thickness. In particular, the multi-thickness lens may be inserted into a goggle, including goggles configured to receive standard lenses. Further, the goggle may include features that may allow the multi-thickness lens to distribute forces and/or stresses to the goggle and/or may include features and/or components adapting the goggle to receive a multi-thickness lens.

A pair of eye goggles is provided. The pair of eye goggles includes a nosepiece fittable over a portion of a wearer's face, the nosepiece comprising one or more strands, at least a portion of the nosepiece comprising a phase change material, wherein a shape of the nosepiece changes upon an application of an energy to the phase changing portion to conform to the face; and a pair of eyepieces connected to the nosepiece.

A laser protection eyewear lens includes a lens substrate comprising an embedded wavelength filter having a first filter function, and a multi-layer dielectric filter applied to at least one of an inside and an outside surface of the lens substrate that comprises a second filter function having at least one center wavelength and bandwidth. The first filter function of the embedded wavelength filter and the second filter function of the multilayer dielectric filter produce a combined filter function that attenuates light reflecting off the multi-layer dielectric filter.

A goggle includes a goggle frame, a lens assembly including a lens mounted on the goggle frame, two reels rotatably mounted on the goggle frame on opposing left and right ends of the lens and a soft sheet mounted between the two reels and abutting the outer surface of the lens, and a control assembly that can be set on one of the two reels according to the dominant hand of the wearer. With this, once the soft sheet is dirty, the wearer operates the control assembly with his dominant hand, so that the control assembly drives the reel set to rotate. At this time, the driven reel will further drive the soft sheet to move laterally relative to the lens, and then roll up the dirty part, so that the soft sheet can always be kept clean in the part corresponding to the lens.
