Benefits of technology

"The present invention relates to eyeglasses with an auxiliary frame that can be attached to the primary frame using magnetic members. The frames are designed to allow for easy attachment and detachment of the auxiliary frame, and the magnetic members are used to secure the frames in a variety of orientations. The technical effect of this invention is to provide a more convenient and versatile way to wear eyeglasses with sunlight protection or for other purposes."

Problems solved by technology

Typically, the auxiliary lens is secured by mechanical clips but difficulty in attaching the clips has led to the adoption of magnetic retention for the auxiliary lens.

Embodiment Construction

[0040] Referring therefore to FIG. 1, eyeglasses 10 includes a primary frame 12 having a pair of lens openings 14, 16 interconnected by a bridge 18. Corrective lenses 20, 22 are received in the openings 14, 16 respectively.

[0041] Side arms 24, commonly referred to as temples, are connected by a hinge 26 to the temple region 28 of the primary frame. The temple region 28 is formed at the intersection of an upper frame member 30 and lens rim loop 32. It will be appreciated that the frame member 30 and rim loop 32 are moulded to provide a unitary construction although alternative constructions using individual components are envisaged within the scope of the invention.

[0042] The upper frame member 30 has an upwardly directed surface 32 that extends into the temple region 28. A notch 34 is formed in the upper surface 32 adjacent to but inwardly spaced from the end 36 of the temple region 28. As seen in FIG. 4, the notch extends across the main frame member 32 so as to intersect the fro...

Abstract

Eyeglasses comprise a primary frame and an auxiliary frame detachably secured to the primary frame by interaction of magnetic members on the frames. The frames and magnetic members are configured to maintain the frames in a first orientation in which the auxiliary frame overlies the primary frame and a second orientation in which the auxiliary frame is disposed above and away from the optical axis of lenses carried in the primary frame.

Description

FIELD OF THE INVENTION [0001] The present invention relates to eyeglasses. BACKGROUND OF THE INVENTION [0002] Eyeglasses are of course a well-known expedient to correct defects in the vision of the wearer. Eyeglasses are also used to shield the eyes of the wearer from adverse conditions, particularly bright sunlight. [0003] For users of eyeglasses with corrective lenses, it is not unusual to provide additional auxiliary lenses that can be attached over the lenses of the corrective eyeglasses to provide protection against sunlight. Typically, the auxiliary lens is secured by mechanical clips but difficulty in attaching the clips has led to the adoption of magnetic retention for the auxiliary lens. [0004] In normal use, the auxiliary lens will either be attached to or detached from the primary lens as the ambient light conditions vary. However, in certain situations, such as when driving a vehicle, it is desirable to retain the auxiliary lens on the primary lens even when the auxiliar...
