Wah lah!

I received my very first free pinhole glasses. I am so excited! I have signed up to test and review this product. I have actually seen one of these pinhole eyeglasses in my local pharmacy. I was wondering what it was. I did a little online research to investigate how it works.
Pinhole Glasses consist of a series of pin size holes about 1 mm on the lens. Light enters our eyes through these pinholes, reduces the size of the circle of confusion as the restricted rays are coming straight from the viewed object. These rays do not need focusing which makes the image clearer in our eyes.

I was surprised when I tried it on without my prescription glasses, everything is so clear. By the way I am short sighted. It is kind of cool. However I still have trouble reading words far or near. I guess it takes longer for my eyes to adjust to it. Some folks claim that these pinhole glasses will improve vision, help myopia or cataracts. However some experts say that there is no scientific proof. One important benefit is that it is 100% harmless. It will not make your eyesight worst.
I will definitely put it to the test. It will be effective if I wear it frequently for at least 6 months. I probably will wear it at home else people will stare at me if I take it out.
I must say that wearing pinhole glasses help my eyes to relax. Prescription glasses can strain my eyes some times. If I read too long or work on my computer too long, my eyes will get tired easily.
It is not very effective when it is use on a dim lighting. It blocks out a substantial amount of light which lowers the quality of the images. Not encourage to use pinhole glasses at poor lighting area. It is also illegal to drive with pinhole glasses.
You have a try, it may work on you. It is cheap too! By the way come back in 6 months and I will tell you whether it has improve my vision.
