How are pinhole glasses different from regular glasses?
The continual use of eyeglasses or contact lenses can cause the eyes to become weaker and weaker, and this is why one pair can be used for only so long before it has to be changed for ‘stronger’ ones. Wearing eyeglasses for long hours in front of a computer screen can cause eye strain, sore eyes and headaches. Pinhole glasses can never have those effects, no matter how long you wear them, and pinhole glasses can never weaken a person’s eyesight. There are no ‘stronger’ or ‘weaker’ pinhole glasses. They are all the same.
