Pinhole glasses are a powerful tool which can help to improve your sight and limit the use of regular glasses or contact lenses. When you wear these pinhole glasses frequently, the eye tension will be reduces which increases the sharpness of your sight.

This effect is caused by the perforated glass which ensures that the light from the side does not reach your eyes. Each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. The glasses work best strengths from -4 to +4, but can also improve visibility at higher or lower values.

Besides, it can also be used with highly frequent work with computer screens. How does that work? Computer screen work increases staring and leads to tiredness, while these glasses forces your eyes to function more actively which reduces the amount of staring.
