Pinhole Glasses
If you are starting to need reading glasses and want to strengthen your eyes these really work.
You wear them for 15 minutes a day when you are reading and the pinhole effect lets less information through to the retina and the muscles around the eyes move the information into clarity so you can read without spectacles. Then when your muscles are practiced they can move your eyes into the correct place for seeing naturally.
Not for driving and they don't work on extreme eyesight conditions more in the 40- 55 year old bracket when eyesight seems to be less effective.
Most people who try them in my shop say "Wow I can read" and are amazed on about 90% of people.
I have four different types and they all seem to work the same so it will be a random choice in sending unless you can specify number 1 2 3 4 but not all are in stock at all times
