Abstract: An anti-fog lens including a lens and an anti-fog layer. The lens having a first surface and a second surface. The anti-fog layer is disposed on a side of the first surface and a side of the second surface, and includes a modified cellulose triacetate (TAC).

Abstract: An embodiment includes a snap-fit temple interface of a lens. The snap-fit temple interface includes a first snap-fit feature and a second snap-fit feature. The first snap-fit feature of the lens is configured to be engaged with a first corresponding snap-fit feature of a temple assembly. The first snap-fit feature is configured to be engaged with the first corresponding snap-fit feature by a first movement of the lens in a first direction relative to the temple assembly followed by a second movement of the lens in a second direction relative to the temple assembly. The second snap-fit feature of the lens is configured to be engaged with a second corresponding snap-fit feature of the temple assembly. The second snap-fit feature is configured to be engaged with the second snap-fit feature by the second movement of the lens in the second direction relative to the temple assembly. The first direction is substantially perpendicular to the second direction.

Abstract: An elastic eyeglass temple includes: a main body; one or more holes which are formed in one predetermined section or respectively in plural predetermined sections of the main body and which, if plural, can be spaced apart or in communication with one another; and one or more flexible members which correspond in configuration to the hole or respectively to the plural holes, which are fitted in the hole or respectively in the plural holes, and which lie compliantly along the main body, such that the one or more flexible members form a single unit with the main body. Once pivotally connected to the corresponding lateral end of an eyeglass frame, the eyeglass temple can stay elastic and provide an elastic contact with a lateral side of the user's head even after it has been pulled outward repeatedly for some time.

Abstract: A goggle structure includes a protective soft pad, a frame, and a subsidiary lens frame. Convex portions are formed on upper and lower sides of the subsidiary lens frame and inserted into slots disposed at the frame, respectively. Hook portions are formed on upper and lower sides of the frame and extend backward. By inserting the frame into a receiving space disposed at the protective soft pad, the hook portions press against the periphery of the receiving space. Pressing portions and carrying portions are formed on upper and lower portions at the middle segment of the frame and adapted to hold the protective soft pad. The bottom of the subsidiary lens frame straddles the pressing portions and carrying portions. Branch portions extend from two outer sides of the frame to press against a concave portion of the protective soft pad. Hence, related components are engaged with each other.

Abstract: A goggle lens positioning structure includes a protective soft pad, a frame, and a lens. The lens and the frame are coupled together by following the steps below. Pressing portions and carrying portions disposed at upper and lower sides of the frame and extending forward are inserted into concave portions concavely disposed at corresponding portions of the lens. After penetrating holes disposed at corresponding portions of the lens, branch portions extending from two outer sides of the frame leave a hole at one end of a fastening unit to restrict movement. The frame is received in the receiving space of the protective soft pad to effectuate engagement therebetween. Hence, the lens and the frame can be quickly put together and easily separated.
