Pinhole glasses- a review:

Review of pinhole glasses:
Pinhole glasses are now a viable alternative to regular spectacles using lenses. These consist of a metal frame supporting plastic lenses with multiple fine perforations, drilled using precision lasers. The advantage of pinhole glasses is that they allow only coherent and direct light rays to enter the eye, thus improving vision and reducing eye stress.
The fine pinholes on the surface of the plastic lenses of the pinhole glasses act to reduce the aperture of the eye's pupil, thus conducting a very narrow beam of light through to the eye lens. This narrow beam causes less blurring of the image formed on the retina, thus resulting in improved vision. Find out more about how pinhole glasses work here.
Many users of this novel technology (pinhole glasses) have reported better vision and less eye strain on prolonged use. Another major advantage is that one pair of glasses suits all conditions, be it reading book or watching distant objects. These glasses are also lightweight and weigh about the same as other spectacles. These are sturdy and durable. Pinhole glasses are resistant to scratches and do no break. Are you worried about whether these will suit worry again.. these are available in variety of shapes and are stylish, following current trends.
What is the cost? These glasses are available for US $ 19.99 At this price these modern glasses are a viable alternative to expensive conventional spectacles which can cost many times more. Did you know that ophthalmologists also use pin hole lenses whilst examining the patient’s eyes? Many users have found that pinhole glasses are less stressful than using multifocal or varifocal glasses. The pinhole lenses also cause apparent brightening of dimly lit objects, especially during night time. Thus one can easily see better in the night.
