Pinhole (Stenopeic) glasses are a type of corrective eye wear that can improve the vision in persons who are farsighted, nearsighted, have astigmatism or who have decreased vision due to aging. Traditionally, an eye doctor performs a manifest refraction to determine the prescription or power that is needed to properly correct the vision in each eye. If prescription glasses are needed frames and lenses can easily turn into a costly necessity, especially if bifocal lenses are required.
With pinhole glasses, there is no need for a prescription and the same pair can be used to correct both near and far vision. They are made with a series of 1mm dots or holes in an opaque plastic lens. When a person looks through these holes, only central light rays are allowed to pass into the eye and peripheral light is blocked. By reducing the amount of indirect light, the normal blur circle that appears on the back of the eye (the retina) is reduced. Reducing the circle of blur achieves the appearance of clearer vision. While these glasses do not actually improve visual acuity, they do decrease the amount of visible blur.
Pinhole glasses are not ideal for all people and situations and will not entirely replace the need for prescription glasses. There are several limitations to wearing this type of corrective eye wear that should be taken into account. Because the amount of light allowed to enter the eye has been decreased, the need for brighter light to compensate is increased. For safety reasons they should not be worn while driving or outdoors as a replacement for sunglasses. They do not have the proper protection from ultraviolet rays that prescription sunglasses have and their design does not allow for a full range of vision. Stenopeic glasses are best suited for people who have under 6 diopters of myopia and who use them mainly for stationary work such as reading, writing, watching television or at the movies. Despite their limitations pinhole glasses do offer a low cost solution for certain tasks and are worth discussing further with an eye care professional.

Pin hole glasses are meant to improve your vision so that you will no longer need to wear glasses or contact lenses. These glasses look like a pair of sunglasses that have an opaque disc with rows of pin holes in it. By wearing a pair of pin hole glasses for 30 minutes a day you will be able to cure your problems with such things as astigmatism, double vision, sensitivity to light and cataracts.
This is not a new concept. In fact, doctors knew centuries ago that this would work. There is actually a very simple reason behind the reason that they do work. The reason is that whenever light passes through a series of small holes the light is restricted to only those rays that come directly from the object that the person is looking at. As such, you will not need to focus in order to be able to bring the object to a point and thus be able to view it clearly.
All you have to do is look through a pin hole to understand how these glasses work. You will see that blurry objects will become more focused since the amount of rays that are responsible for making things look blurry (peripheral light rays) will be reduced. Therefore, whenever pin holes are appropriately spaced a person will be able to have clear vision.
There are many great testimonials available online today about how well pinhole glasses work. One user even said that once he had worn these glasses for 20 minutes he was able to read street signs from a far distance without using his glasses.
These pinhole glasses are expensive unfortunately. However, this is a small price to pay for those who are tired of wearing corrective lenses. This is especially true whenever you stop to consider that you will never be able to reach these results simply by wearing a pair of conventional eyeglasses.

Pinhole glasses are made of an opaque substance such as metal or plastic. Glasses are not made of glass at all. They are know as stenopeic glasses from the Greek words for “little opening”. The user looks through any of the many small holes in the material.
Completely natural, effective, durable and affordable. Pinhole glasses are an alternative to your conventional glasses providing clear vision. They are 100% safe to use and will not harm your eyes. Use the glasses to overcome impaired vision owing to any common refractive eye disorders. They block indirect rays from entering the eye thus preventing them from distorting your vision. Allows only direct and coherent light rays to pass through. They refresh your tired eye muscles and keep eyes from staring. Also, improve clarity and sacadic motion.
There are two distinct forms available for pinhole glasses. They are Traditional pinholes and Model pinholes. The ideal combination would be to use the traditional pair at home and use the model in public. One pair suits all purposes, whether it is for reading, working on the computer, or watching television.
Pinhole glasses are not just for adults but beneficial to children with myopia. They can prevent the onset of acquired myopia in children. They reduce the amount of light entering your eyes so they cannot be used in an environment having dim lights.
Some of the disadvantages of the pinhole glasses are they shall not be used while operating machinery, or any activity involving motion. Some users have said glasses cause multiple images. Some of the advantages include a clearer image at all distances and the life of the glasses last a long time. Also, they do not require any upgrade like prescription glasses. The older pinholes were flat with holes punched through them. But nowadays they have a new look that looks more like sunglasses with the holes on the inner side of lenses.

Pinhole glasses, also called stenopeic glasses are made from an opaque substance that allows many tiny holes in the material through which one can obtain better vision. These glasses are created for people with conditions such as presbyopia, myopia, hyperopia and astigmatism. They are not intended to treat these conditions, only to enhance one’s vision.
The pinholes work by blocking peripheral rays and only allowing rays to pass through the centrally portioned aspect of the pupil. The pupil can be open wide but pinhole glasses will only allow the rays to be passed to that one certain area. As an example of how this works, one can hold a comb in front of their eyes and look through the teeth of it. Essentially, this will give the same effect as pinhole glasses.
While pinhole glasses are a bit on the expensive side, although much cheaper than prescription glasses, they do have several advantages over regular prescription glasses. Unlike prescription glasses that only get weaker over time, pinhole glasses will last a lifetime unless the pinholes happen to break. Scratching of the lens on prescription glases has a great impact on the ability to see clearly; scratches on pinhole glasses does not the alter the ability to see. Pinhole glasses do not need to be cleaned of fingerprints and other smudges as do regular prescription glasses.
People who suffer with cataracts, the passing of light which causes it to scatter, find that pinhole glasses provide a great improvement in their vision. The glasses are also used in the prevention of Myopia, especially in school-aged children who have trouble viewing the board.
Pinholes do have certain limitations and there are some instances where they are not recommended for use.
When using them, there should be an adequate amount of light to focus on the object you are viewing. Also, young people who are very farsighted should not use pinholes.
While pinholes are not intended to treat certain conditions, they are highly effective when used for reading or other up-close work by reducing the amount of focus strain on the eye.

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 have been around in various forms for many years and today, you can benefit from the latest in laser technology as it can produce the crispest, most precise perforations in the lenses of the glasses for optimal vision. If you are unsure of what pinhole glasses are, they consist of either a plastic or metal eyeglass frame with the lenses sporting tiny pinholes or perforations which directly focus light into the eye.
When your vision is not perfect, it is because the light reflecting into the back of the eye called the retina does not focus on a single point, like it does for people with good vision. Instead, the light diffracts causing blurred vision. The purpose of the small perforations in the pinhole glasses is to narrowly focus the rays of light into the eye to achieve clearer vision. There are several benefits of these glasses:
- Clearer vision and the ability to distinguish close objects from one another
- Brighter focus on objects, particularly if light is poor in a space
- Great vision regardless of whether you have problems seeing near or far
- Versatility in use whether you are watching TV, typing at the computer or reading a book
- Sturdy construction and no worries about lens scratching obstructing vision
- Inexpensive
Pinhole glasses are best used in situations where you are stationary such as computer work, reading a book, watching television or in a classroom. Fast moving activities such as sports and driving require peripheral vision and the pinhole glasses can only focus light rays directly into the eye, not from the sides.
If you have severe refractive eye disorder with a diopter measurement more than 6, you may not benefit from pinhole glasses. However, if you are experiencing average near-sightedness, far-sightedness, astigmatism, presbyopia or eye strain from computer work, pinhole glasses are a great option for improving your vision. Even kids can benefit from them.
Overall, you have nothing to lose by trying pinhole glasses, especially because they are quite a bargain in comparison to prescription eyeglasses. Try pinhole glasses first to see how well your vision improves before opening your wallet at the optometrist.

When we experience blurred vision, we make a quick call to the opthomologist, get an eye exam and buy one of those expensive prescription glasses. Most people know very little about pinhole glasses.
Pinhole glasses are not made of glass but of an opaque material such as plastic or metal. The person wearing these glasses looks through any of the many holes in the material. There are 2 major issues with the prescription. Improper use would leave the lens with scratches and you may have to use different glasses for reading and distance viewing. With the pinhole glasses, these drawbacks are eliminated. They provide clear vision at all distance and one need not switch glasses between watching TV and reading a book and scratches on the pinhole glasses does not affect the performance of these glasses.
Pinhole glasses reduce the scattering of light and improve the vision which helps people with cataract to see well. These glasses are better than the conventional sunglasses too. If you have ever experienced visual stress from looking at the computer, these glasses work best to reduce the stress on the eyes. These glasses play an important role in myopia prevention. It is very sad that a “minus” prescription is given to a child who cannot see the board clearly in school. The simple solution would be to have a couple of pairs of pinhole glasses in each classroom and the students could use them when they have a difficulty reading the board. It is an inexpensive way to treat the problem and completely avoids the risk involved in using a prescription glass for myopia in children.
Did anyone imagine that the pinhole had so many advantages over the prescription glasses? However, these pinhole glasses have their limitations. These glasses do not completely eliminate the blur with people over 6 diopter of myopia. Since the pinholes glasses blocks some light, it is essential to have good lighting on the viewed object. These glasses should not be used while driving or in motion.
Pinhole glasses cannot completely replace the prescription glasses. But these are an inexpensive and a better option for people with mild myopia and for those who use reading glasses.
