1. An apparatus for connecting first and second eyewear ends, the apparatus comprising:
a strap including a first strap end and a second strap end;
a first connector at the first strap end, wherein the first connector comprises a first base, a first head, and a first shaft extending between the first base and the first head, the first base comprises a surface that faces the first head, and the first head comprises a surface that faces the first base;
a second connector at the second strap end, wherein the second connector comprises a second base, a second head, and a second shaft extending between the second base and the second head, the second base comprises a surface that faces the second head, and the second head comprises a surface that faces the second base;
a first fastener including:
a first attachment end configured to attach removably to the first eyewear end; and
a first connection end comprising a first connection layer and a first hole through the first connection layer, wherein the first shaft of the first connector extends through the first hole of the first connection end of the first fastener, and the first connection layer is between the first base and the first head of the first connector; and

a second fastener including:
a second attachment end configured to attach removably to the second eyewear end; and
a second connection end comprising a second connection layer and a second hole through the second connection layer, wherein the second shaft of the second connector extends through the second hole of the second connection end of the second fastener, and the second connection layer is between the second base and the second head of the second connector;

wherein the surfaces of the first and second bases that face the first and second heads, respectively, and/or the surfaces of the first and second heads that face the first and second bases, respectively, are textured surfaces including bumps, dots, protuberances, and/or ridges; and
wherein:
an amount of friction of both (a) the surface of the first base that faces the first head and the surface of the first head that faces the first base against the first fastener is such that both (i) the first connector is allowed to rotate relative to the first fastener at times including when a user moves the strap relative to the first and second fasteners and (ii) the first connector is prevented from rotating relative to the first fastener at other times; and
an amount of friction of both (a) the surface of the second base that faces the second head and (b) the surface of the second head that faces the second base against the second fastener is such that both (i) the second connector is allowed to rotate relative to the second fastener at the times including when the user moves the strap relative to the first and second fasteners and (ii) the second connector is prevented from rotating relative to the second fastener at the other times.
