Are pinhole glasses a viable alternative to traditional eyeglasses?

June 30th, 2009

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.

What Pinhole Glasses Are

June 24th, 2009

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

June 22nd, 2009

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

June 21st, 2009

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.

Are Pinhole Glasses Right For You?

June 19th, 2009

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.

Benefits and Answers about Pinhole Glasses

June 19th, 2009

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:

  1. Clearer vision and the ability to distinguish close objects from one another
  2. Brighter focus on objects, particularly if light is poor in a space
  3. Great vision regardless of whether you have problems seeing near or far
  4. Versatility in use whether you are watching TV, typing at the computer or reading a book
  5. Sturdy construction and no worries about lens scratching obstructing vision
  6. 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.

Pinhole glasses for blurred vision

June 18th, 2009

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.

Pinhole Glasses: An Affordable Alternative to Perfect Vision

June 16th, 2009

Every year, many people suffer from blurry vision. Therefore, people visit their eye doctor to get a prescription for a pair of eyeglasses. While eyeglasses protect the eyes from various flying objects during a windy day and improve eyesight, they are very flimsy and they break very easily. Also, some eye doctors write the wrong prescription forcing their patients to wear bifocal glasses or trifocal glasses. As a result, many people decide to forgo their prescription glasses and invest on pinhole glasses.

Pinhole glasses don’t require lens and they are specially designed to improve vision by reflecting bright light through tiny round holes. Also, pinhole glasses costs twenty dollars and doesn’t require medical insurance. People can easily correct their vision without buying expensive medical insurance or visiting their eye doctor. In addition to the friendly price tag for consumers, pinhole glasses can be used as sunglasses or computer glasses. Pinhole glasses lasts a lifetime because they’re made out of an assortment of strong materials, and pinhole glasses are a safe and affordable alternative to expensive prescription glasses.

Expensive prescription glasses are priced between eighty dollars and a hundred and fifty dollars. These costs are a burden for consumers who don’t have medical insurance. Therefore, consumers without medical insurance will have an increase risk of obtaining consumer debt. In addition to consumer debt, prescription glasses need to be replaced every year. Also, prescription glasses need to be properly inserted in an eyeglass case to prevent scratches on the lens or smudges on the lens. As a result, prescription glasses are a gigantic responsibility to maintain.

In addition to the gigantic responsibility for maintaining prescription glasses, bifocal glasses and trifocal glasses are very dangerous. For example, when a person is in their Toyota and checks their side view mirror, there’s a fine print message in capital letters that displays, “objects in mirror are closer than they appear”. The same warning applies to bifocal glasses and trifocal glasses because they contain two or three lenses causing objects to zoom in. As a result, people have fallen from flights of stairs and suffered numerous injuries from wearing bifocal glasses or trifocal glasses.

Overall, pinhole glasses are safer than prescription glasses. By investing in pinhole glasses, many people will avoid consumer debt and they will be able to improve their vision. Also, there is no lens in a pair of pinhole glasses, so there are less injures and less accidental incidents. As a result, there will be less medical bills and people won’t have to worry about the consequences of being medically uninsured.

How Pinhole Eyeglasses Work

June 15th, 2009

Not a lot of people know what pin hole glasses are or how they can be used to improve both far sighted and near sighted problems. However, there are a lot of benefits to learning more about pin hole glasses.

These glasses, which are also known as stenopeic glasses,” have small openings in them. They are meant to improve upon a person’s vision. This is done by the small little pinholes that are found within the glasses’ lenses. The openings will lessen the amount of light that is able to enter into the eyes (the same effect that you will get by making a fist and looking through its tiny opening). Whenever this occurs you will be able to see objects more clearly. It also helps that lights that come from outlying areas will be blocked out and thus light will only be able to enter into the middle part of your pupil. In turn, refractive error will be reduced while your eyesight will be improved.

Pin hole glasses will improve upon your eyesight regardless of the distance. These glasses will cost you less than a pair of prescription eyeglasses but they are going to cost you a little bit more than a pair of reading glasses. Whenever you put a pair of pin hole glasses on you will notice that there is very little glare or distortion. You will be able to wear them for a long time before you will ever need to do any type of maintenance upon them.

There are actually two different styles of pin hole glasses available. The first type are traditional and have wider lenses with a little bit of a curvature. You will be able to see the holes in the lenses of these glasses. These will also lessen the amount of ultraviolet light that reaches your eyes. The second type are modern and have a more attractive design. This type of pin hole glasses looks like a pair of sunglasses and will provide you with full protection from ultraviolet light. Their holes are not nearly as noticeable.

Understanding Pinhole Glasses

June 14th, 2009

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.
