When your eyes are placed behind normal prescription glasses, you fall into a trap where you no longer use the focusing muscles in your eyes to the fullest. This important ciliary muscle begins to weaken, requiring visits to your eye doctor for stronger and stronger glasses. You can reverse this downhill slide and help develop your eye muscles now by using pinhole glasses.
The ciliary muscle /ˈsɪli.ɛəri/ is a ring of smooth muscle in the eye's middle layer (vascular layer) that controls accommodation for viewing objects at varying distances and regulates the flow of aqueous humour into Schlemm's canal. It changes the shape of the lens within the eye, not the size of the pupil which is carried out by the sphincter pupillae muscle and dilator pupillae.
The eye's ciliary muscle contracts, causing the eye's natural lens to thicken or change shape, which allows us to see objects up close. Presbyopia develops as we age, when our lens becomes less flexible and resists changing shape. With presbyopia, up-close focusing becomes more difficult.
Pinhole glasses - sports style. Pinhole glasses work by exercising your ciliary muscle group that alters the shape of your lens. An "out of shape" eye lens causes an inability to focus images on the retina, resulting in blurred vision. Pinhole glasses exercise the ciliary muscles, helping restore a normal range of focus that restores clear vision.
