Pinhole Grid Glasses for Short-sighted People

The modern and affordable alternative to prescription eyeglasses, pinhole glasses consist of precision-manufactured lightweight perforated plastic lenses, inset into standard metal or plastic spectacle frames. They are ideal for sufferers of refractive eye disorders, the elderly and computer users as the pinholes - accurately formed by laser technology - allow only direct and coherent light rays to pass through into the eye.

Pinhole glasses are a type of corrective glasses that do not use a lens and are claimed to help correct the eye's refractive error without introducing the image distortion of traditional lens-based glasses. Pinhole glasses do not actually refract the light or change the focal length, they operate by reducing the size of the blur circles in the retinal images. In blurry vision, every point on the object corresponds with a blur circle in the image. By reducing the size of the blur circles, they reduce the overlap of the blur circles in the image, clarifying the vision somewhat.

How does pinhole glasses 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 glasses1.Improves vision clarity & resolutionFor sufferers of refractive eye disorders, pinhole glasses will improve the clarity & resolution of vision.2.Increases object brightnessPinhole glasses are proven to increase apparent object brightness - ideal if you struggle with vision in low-light situations3.Good vision at all distancesUnlike 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.

Key features1.One pair suits all situationsWhether you are reading a book or watching TV, one pair of pinhole glasses is all you'll ever need. 2.LightweightAll modern-day pinhole glasses are lightweight, weighing no more than traditional spectacles.3.DurableNo need to worry about scratches & marks on the lenses. The performance of pinhole glasses is not adversely affected by defects that would otherwise degrade visual acuity through eyeglasses.4.Attractive Design & Affordable
