 Unisex Sports Style Pinhole Glasses Eyesight Vision Improve 


Pinhole glasses, also known as stenopeic glasses, are eyeglasses with a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens. Similar to the workings of a pinhole camera, each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. In eyes with refractive error, the result is claimed to be a clearer image. However, a second effect may appear at the common bridge between each two adjacent holes, whereby two different rays of light coming from the same object (but each passing through a different hole) are diffracted back toward the eye and onto different places on the retina. This leads to double vision (objects having doubled edges) around the rim of each hole the eye is not focussing on, which can make the overall image disturbing and tiring to look at for prolonged periods of time.


Unlike conventional prescription glasses, pinhole glasses produce an image without the pincushion effect around the edges (which makes straight lines appear curved). While pinhole glasses are claimed to be very useful for people who are both near- and far-sighted, they are not recommended for people with over 6 diopters of myopia. Additionally, pinhole glasses reduce brightness and peripheral vision,and thus should not be used for driving or when operating machinery


How does it work

In a healthy eye, light rays are focused into a single point on the light sensitive retina at the back of the eyeball. Depending upon the type of refractive disorder endured, less healthy eyes focus light rays in front of or behind the retina, casting a 'blur circle' on the retina itself. The minute pinholes on the surface of the plastic lenses of your pinhole glasses effectively stop down the aperture of the eye's pupil, so pass a narrower beam of light through to the eye lens with a greater depth of field. The narrow beam casts a smaller blur circle on the retina, improving your vision.


The benefits of pinhole glasses
1.Improves vision clarity & resolution
For sufferers of refractive eye disorders, pinhole glasses will improve the clarity & resolution of vision.

2.Increases object brightness
Pinhole glasses are proven to increase apparent object brightness - ideal if you struggle with vision in low-light situations

3.Good vision at all distances
Unlike bi-focal and tri-focal glasses that are designed to yield good vision at fixed distances, pinhole glasses allow you to see clearly at all distances, whether short, middle or long distance focus is required. Many users also find them less stressful on the eye than multi-focal or vari-focal lenses.
