Pinhole glasses are eyeglasses with a series of holes in them that allow the wearer to receive less light directly to the retina which in turn increases your field of vision. They are made from solid materials such as plastic or metal and can be disguised to look like modern sunglasses.
The glasses have the effect of reducing the width of the bundle of oncoming rays from each viewed object. Normally whenever you glance at something the full opening of your pupil accepts light, but with pinhole glasses you are receiving a bent fraction of that amount of light. If you are troubled with conditions such as myopia, hyperopia, presbyopia, or an astigmatism then pinhole glasses will increase your ability to see longer distances and see with a higher quality of detail.
The basic concept that the glasses work on is that no matter how wide open your pupils are only the central portion is receiving light. The pieces of plastic or metal inbetween the holes makes sure to keep light from reaching the outer edges of your pupil which in turn increases your focus and vision.
An easy way to demonstrate the affect of the pinholes is to close one eye while making a fist and holding it up to your open eye. Now slowly open your fist so just enough light shines though for you to see. If you do this correctly your vision will be remarkably better than when a full amount of light is hitting your pupil.
The pinhole affect can trace its origins to native Alaska. The natives would wear glasses with narrow slits in them to block out the intense glare received from the sunshine that is reflected off the snow and ice. Anyone who lives in a snowy environment for long periods of time can develop snow blindness from the glare which can only be healed by avoiding light.
From native beginnings to modern eyewear pinhole glasses have long been used to increase the focus and vision of those people who utilize this light blocking technology.

If you have an eyeglass prescription from your doctor, don’t fill it quite yet. Consider an alternative to expensive eyeglasses that could have you seeing clearer than you have in a while. Pinhole glasses are an inexpensive option to prescription glasses. They have either metal or plastic frames which house precisely constructed plastic lenses with lightweight perforations in them. If your eyesight has degenerated because of age, excessive computer use or even due to refractive eye issues, pinhole glasses can definitely help your vision. The perforations are constructed using laser technology and let in direct rays of light which go through into your eye.
With people who have great vision, rays of light that enter into the eye are reflected into a single point on the retina, located behind the eyeball. If you have a refractive eye disorder or some other vision problem, these light rays do not accurately reflect on a single point, thereby causing blurry vision. With pinhole glasses however, the little holes effectively direct light rays into the eye where they are reflected on the retina in a tighter space, thus reducing the blurry or hazy vision.
As long as you have no known degenerative eye condition, pinhole glasses will help you see more clearly in just a short time. They can help with your astigmatism, near-sightedness, far-sightedness, presbyopia (gradual vision degeneration due to age), vision problems due to computer use and even cataracts. While an eyeglass prescription may change every few years, the pinhole glasses remain the same, effectively improving your vision. Why pay hundreds of dollars every few years for new prescription eyeglasses when you can spend far less for a pair on pinhole glasses that will last a lot longer?
Pinhole glasses are not a trend that is going to fall out of favor. They have actually been around for years but have recently become more popular as the cost of prescription eyeglasses are sometimes too cost prohibitive. Even medical professionals are more accepting of them. Consider trying pinhole glasses before heading to the optometrist. You will likely not make the trip.

Pinhole glasses, which are also known as “stenopeic glasses,” are glasses that have a series of small pinholes in them. Their frames are made of either metal or plastic. They are considered to be an affordable modern alternative to eyeglasses since they will provide you with clear vision. An added advantage to them is that they will strengthen your eyes and keep them from growing lazy. These glasses are able to help correct refractive errors such as farsightedness or a diminished focusing range. As such, these are especially ideal for the elderly and for computer users too.
These pinhole glasses work in a way that is similar to the way that a pinhole camera works. The light rays that enter into the weak eye but cannot focus and thus the image is blurred. However, the pinhole glasses help the rays focus on the retina thus producing a clear image. Another benefit to these glasses is that they will help your eye muscles relax as they will no longer have to make an effort to bring things into focus.
This is considered to be a 100% safe eye correction tool for people of any age. Pinhole glasses have some obvious advantages over conventional glasses that make them better to use. Not only will they improve your clarity and resolution but they will increase an object’s brightness and help you be able to see things regardless of their distance. These glasses are also made of a lightweight and durable material which is both attractive and affordable as well.
It is important to note that you should never wear a pair of pinhole glasses when you are driving or operating heavy machinery. This is because they will diminish your peripheral vision. So, while pinhole glasses have replaced a lot of the more traditional eyeglasses that people wear, it is unfortunate that they simply cannot replace these eyeglasses in every situation.
