A method for assembly of an eyewear and an eyewear structure are provided to incorporate preferred properties into the eyewear. A relatively less curved lens is encircled by a protruding rim element, thereby forming a lens unit which is removably attached to the eyewear structure. The protruding rim element has a much curved outer periphery thereof such that the relatively less curved lens can be assembled in a much curved frame structure.

An optical device detachably attached to a frame fixed to a user's head is provided. The optical device includes a body extending in one direction, a display extending in a direction intersecting the one direction, connected to the body, and disposed to be adjacent to the user's eye when fixed to the frame, so as to provide visual information, and a clip module protruding from the body and caught in one region of the frame.

A magnetic mounting arrangement for removably attaching auxiliary eyeglasses to an eyeglass frame. The mounting arrangement includes a male part having a projection thereon and a female part having a recess therein. The male and female parts are permanently attached to the auxiliary eyeglasses and the eyeglass frame such that the projection engages the recess when the auxiliary eyeglasses are attached to the eyeglass frame. The male and female parts can be of a magnetic or magnetizable material. The male part can include a stepped surface which mates with a stepped surface of the female part when the projection is fitted within the recess. The auxiliary eyeglasses can be various types of lenses such as sunglasses, computer glasses, fish tying readers, or magnifying glasses.

Adjustable focus eyeglasses with two lens units, each lens unit having two lens elements. The eyeglasses are focused by adjusting the position of at least one of the two lens elements relative to the other in a direction generally perpendicular to a viewing direction. The relative motion can be linear or pivotal about a pivot location outside the lenses. Applicant provides basic general equations defining the thickness profiles for the lenses and the solutions to these equations are:t=A⁡[uv2+2⁢(α⁢⁢v+1)⁢(α⁢⁢u-sin⁡(α⁢⁢u)) / α3]+B[2⁢(α⁢⁢v+1)⁢(1-cos⁡(au)) / α2)⁢]+C⁡(v⁢⁢sin⁡(au) / α-(α⁢⁢u-sin⁡(α⁢⁢u)) / α2)⁢]+Du+E+F⁡(v)+F⁢⁢1⁢(u,v)⁢u4+F⁢⁢2⁢(v)⁢u3⁢v+F⁢⁢3⁢(v)⁢u2⁢v2+F⁢⁢4⁢(v)⁢uv3,whereA for one of the lenses elements is −A for the other lens element in each lens unit andF(v), F1(u,v), F2(v), F3(v), F4(v)are any functions over the area of the lenses for which derivatives up to at least third order are continuous. At least one of F1(u,v), F2(v), F3(v), F4(v) is non-zero.
