A receptor adapted to be used in conjunction with a glasses frame for receiving a lens, the receptor comprising: a housing that includes an inside wall (202, 204) and an outside wall (232, 234), wherein the walls define a space for receiving a connection element of a lens; the housing including a relief mechanism to allow the space to be increased by displacement of at least portions of at least one of the walls; and at least a first latch located within the space, the first latch corresponding to a first detent, wherein the first detent is defined by the shape of the lens and wherein the first latch provides support for holding the lens in position when the first latch is inserted into the first detent; a second latch located within the space, the second latch corresponding to a second detent, wherein the second detent is defined by the shape of the lens and wherein the second latch further provides support for holding the lens in position when the second latch is inserted into the second detent; and an ear stem receiving end and a lens receiving end, and wherein the edges of the inside wall and the outside wall of the lens receiving end define an opening into the space for receiving the connection element of the lens and, at least one of the inside or outside housing walls includes the relief mechanism characterised in that the relief mechanism includes a horizontal kerf-like slot that runs from the lens edge of the wall substantially towards the ear stem end of the housing for a distance and a substantially vertical kerf-like slot that intersects with the horizontal slot and wherein on at least one end of the vertical slot, the inside or outside wall comprises a hole (210, 212) that is substantially wider than the vertical slot, wherein the kerf-like slots enable an upper portion of the wall to be moved in opposing direction from a lower portion of the wall thereby increasing the size of the opening into the space. a housing that includes an inside wall (202, 204) and an outside wall (232, 234), wherein the walls define a space for receiving a connection element of a lens; the housing including a relief mechanism to allow the space to be increased by displacement of at least portions of at least one of the walls; and at least a first latch located within the space, the first latch corresponding to a first detent, wherein the first detent is defined by the shape of the lens and wherein the first latch provides support for holding the lens in position when the first latch is inserted into the first detent; a second latch located within the space, the second latch corresponding to a second detent, wherein the second detent is defined by the shape of the lens and wherein the second latch further provides support for holding the lens in position when the second latch is inserted into the second detent; and an ear stem receiving end and a lens receiving end, and wherein the edges of the inside wall and the outside wall of the lens receiving end define an opening into the space for receiving the connection element of the lens and, at least one of the inside or outside housing walls includes the relief mechanism characterised in that the relief mechanism includes a horizontal kerf-like slot that runs from the lens edge of the wall substantially towards the ear stem end of the housing for a distance and a substantially vertical kerf-like slot that intersects with the horizontal slot and wherein on at least one end of the vertical slot, the inside or outside wall comprises a hole (210, 212) that is substantially wider than the vertical slot, wherein the kerf-like slots enable an upper portion of the wall to be moved in opposing direction from a lower portion of the wall thereby increasing the size of the opening into the space.
