It's a good product, but the sunshine is sparkling in the holes, it's disturbing. It shades pretty well, so it requires strong light when in use. With my aging eyes, I can easily read with the help, if there is enough light because it even sharpens even the small letters.

For the price I paid I cannot complain about the product. They help reduce eye strain while reading, either on the computer, smart phone, or hard copy books. I prefer to use these compared to cheap reading glasses, which create eye fatigue. My main complaint mainly about these particular pinholes is that they create a haze under certain lighting conditions, mainly when there is sunlight in present. I believe this is due to the reflective properties of the type of plastic material used. When there is less intense daylight they work much better. I have another pair of pinholes which work better in all light conditions and produce less distortion, but which cost much more..

My eyes have improved tremendously. I now am able to read without reading glasses some times. There is an exercise booklet that one should purchase with the pun hole glasses. That book, paired with the glasses is awesome. Trust in my words Peaceful journeys

Pros: 1) Lightweight 2) Sits more than comfortably 2) Does the job even for people with advanced myopia Cons: none really Summary: I had a pair of these plastic glasses many years ago and surprisingly found similair pair on eBay. They are indeed great for eye training, I can confirm that. Narrow holes are just the right size to do the job.

The pinhole glasses of this item allow you to read the subtitles of the television or tablet with an acceptable clarity, and reduce the influence of blue screen light on the brain, which facilitates the production of melatonin for better sleep.
