A method of manufacturing a lens includes: injecting a thermosetting first resin in a first mold, and curing the thermosetting first resin, to form a cover blank having cover parts; removing a part or all parts of the first mold; arranging the cover blank in a second mold; injecting a thermosetting second resin having a greater light absorptance or a greater light reflectance than the thermosetting first resin into the second mold and curing the thermosetting second resin, to form a lens blank having a light-shielding part between adjacent ones of the cover parts; taking out the lens blank from the second mold; cutting the lens blank at the light-shielding part located between the adjacent ones of the cover parts to obtain individual lenses having lateral side walls and flange parts extending outward from lower-end portions of the lateral side walls, which are both covered by the light-shielding part.

The conical ball cone bearing is a high load and reduced pressure kinematic or fixed thrust bearing that allows for a greater load carrying capacity with a reduced contact pressure to be obtained in a smaller package. This bearing maximizes the contact radius over the needed angular translation to reduce the contact pressure. This has two advantages in a kinematic system. First, the reduced contact pressure increases the maximum load the bearing can hold prior to surface failure. Second, the reduced contact pressure reduces the friction on the kinematic contacts, allowing the kinematic system to move more freely and operate with a smoother movement and improved stability.

An electronic device is provided. The electronic device includes a first transparent member and a second transparent member where at least one visual object is displayed, a lens frame receiving at least a portion of the first transparent member and at least a portion of the second transparent member, the lens frame configured to: allow an external electronic device including at least one color-changeable lens to be attached thereto, and allow the at least one color-changeable lens to be aligned with at least one of the first transparent member or the second transparent member if the external electronic device is attached to the lens frame, one or more wearing members extending from the lens frame or coupled to the lens frame, at least one camera disposed in the lens frame and at least partially exposed to an outside through at least one hole formed in the lens frame, at least one first transmission coil disposed adjacent to at least a portion of the at least one camera inside the lens frame, and a power transmission circuit configured to transfer a current to the at least one first transmission coil.
