Benefits and Answers about Pinhole Glasses
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.
