20140368786 | ADJUSTABLE FOCUS SPECTACLES - Adjustable focus eyeglasses where the range of adjustment can be moved. That is, if a pair of adjustable focus eyeglasses have a range of 0 diopters to 2.75 diopters (to provide a 2.75 D ADD for reading for an emmetrope), this invention could, for example, permit the user to move the range from 0 D to 2.75 D to 2.00 D to 4.75 D so as to accommodate a short term change in the user's distance vision requirement. Each eye can be adjusted independently. | 12-18-2014 |
20140247422 | Adjustable Focus Eyeglasses with Dual Unilateral Actuation - Adjustable focus eyeglasses where the range of adjustment can be moved. That is, if a pair of adjustable focus eyeglasses have a range of 0 diopters to 2.75 diopters (to provide a 2.75D ADD for reading for an emmetrope), this invention could, for example, permit the user to move the range from 0D to 2.75D to 2.00D to 4.75D so as to accommodate a short term change in the user's distance vision requirement. Each eye can be adjusted independently. | 09-04-2014 |
20140028971 | Eyeglasses to compensate for fluctuating vision - Adjustable focus eyeglasses where the range of adjustment can be moved. That is, if a pair of adjustable focus eyeglasses have a range of 0 diopters to 2.75 diopters (to provide a 2.75 D ADD for reading for an emmetrope), this invention could, for example, permit the user to move the range from OD to 2.75 D to 2.00 D to 4.75 D so as to accommodate a short term change in the user's distance vision requirement. Each eye can be adjusted independently. | 01-30-2014 |
20130229617 | VARIABLE FOCUS SPECTACLES WITH BIPOLAR LENS UNITS AND FRONT MASKING LENSES - Variable focus spectacles including bipolar variable focus lens units and a front masking lens disposed in front of each variable focus lens unit. Each bipolar variable focus lens unit has a transparent rigid member, a transparent distensible membrane, a membrane support on which the membrane is mounted, a transparent liquid of a fixed volume filling in a sealed space between the rigid member and the membrane, and is connected to a bidirectional actuating mechanism for urging the membrane support and the rigid member to move toward and away from each other. Each front masking lens may have any suitable shape so long as its front surface is convex and reflections off that front surface typically dominate reflections off the underlying distensible membrane. | 09-05-2013 |
20130176528 | ROTARY ACTUATION MECHANISM FOR VARIABLE FOCUS SPECTACLES - A rotary actuation mechanism for variable focus spectacles is disclosed. The spectacles include two variable focus lens units and a bridge therebetween. The actuation mechanism includes a rotary cam rotatably mounted on the bridge, a fingerwheel attached to the rotary cam to rotate it, a cam follower disposed in slidable contact with the peripheral surface of the rotary cam, and two elongated couplers pivotally mounted on the bridge. The peripheral surface of the rotary cam is spiral shaped to transfer the rotation of the rotary cam into a linear, or pivoting, motion of the cam follower. Each coupler has a proximate end in contact with or attached to the cam follower and a distal end coupled to a linkage anchor of a respective lens unit, to transfer the motion of the cam follower into simultaneous pivoting motions of the linkage anchors thereby adjusting the focal lengths of the lens units. | 07-11-2013 |
