An eyewear frame of improved comfort, including a one-piece non-folding eyewear frame to which a shield is attachable to provide eyewear, the frame being made of plastic having a flexural modulus of from about 250,000 psi to about 310,000 psi (ASTM D790A), with the frame having a brow piece and a pair of symmetric left and right ear pieces extending away from the brow piece at opposite ends of the brow piece, each ear piece terminating at a free end, with the free ends of the brow pieces being spaced apart from one another to define a gap, with the frame having a maximum width such that the ratio of the maximum width to the gap is above 3.

A temple assembly for a pair of spectacles, including a spectacle temple body, a guide member, a first temple core, a second temple core, a first pivot; and a second pivot; wherein the second temple core is elastically connected with the spectacle temple body, the guide member is sleeved onto the first temple core, two connecting end of the first temple core is respectively pivotally connected to the second temple core and a pile head of a rim, the first pivot and the second pivot are disposed perpendicular to each other. When the spectacle temples are subjected to loads in two different directions from a horizontal direction and a vertical direction, the spectacles temple cause to produce an elastic bend of different directions at a front end and a rear end of the guide member, the user experience that the temples can be rotated 360 degrees is better.

Secure eyewear includes a face piece and a temple piece. The face piece includes a first side, a second side and a nose rest therebetween. The temple piece extends from a first end coupled with the first side and/or the second side of the face piece to a second end and includes a first extension. The first extension is configured to, with the nose rest supported by a nose of a user and the first temple piece resting on a first ear of the user, selectively grip a back of a head of the user by transitioning between states.

Improved augmented reality smartglasses ensure alignment of displays in a head-mounted wearable device such as AR smartglasses by specifying a relationship between material properties of the frame at the shoulder and nose bridge. For example, such a material relationship may be a rigidity and/or stiffness characteristic. In some implementations, the specified relationship is that a difference between the first bending stiffness and the second bending stiffness is less than a tolerance (e.g., 5%, 1%, or less than 1%).
