1. Who and when were the Vision Therapy Eyewear or Pinhole glasses invented?
a. It is not known who invented the pinhole glasses, but the scientific principles of pinhole effects were discovered many centuries ago. Pinhole glasses are widely sold in America, Europe and Australia as substitutes to prescription glasses since the 1950’s at least.
b. The basic optical principles of the pinhole are commented on in Chinese texts from the fifth century BC. Chinese writers had discovered by experiments that light travels in straight lines. The philosopher Mo Tsu was the first – to our knowledge – to record the formation of an inverted image with a pinhole or screen.
c. Aristotle (fourth century BC) comments on pinhole image formation in his work Problems. d. Sir David Brewster, a Scottish scientist, was one of the first to make pinhole photographs, in the 1850s.

2. What is the benefit of the Eyewear?
a. It helps relief strain and stress caused by prescription glasses, and yet enabling clearer vision.
b. Promotes an important vision habit to perfect vision – central vision, since you can see clearly
only straight ahead centrally.
c. Trains your mind, eyes and muscles to see without dependence
on your prescription eye crutches.

3. Are there side-effects?
a. None, except that due to the restricted peripheral vision, one should not wear the Eyewear when driving or moving about outdoors for safety considerations.

4. When and how long do you wear the Eyewear?
a. Frequent substitute of prescription glasses (TV, computer, reading) with the Vision Therapy
Eyewear will result in improved vision, natural, risk and drug-free.
b. You are likely to experience 10-20% vision improvement in 2-4 weeks.
c. For severe myopic, astigmatic and presbyopic
cases (>5.0 diopter), stepped-down prescription glasses are helpful when used in conjunction with the Eyewear.

5. How long do we need to wear the Eyewear to experience vision improvement?
a. It is not the length of time wearing the Eyewear to achieve vision improvement but reducing or eliminating the root cause of vision challenges – stress and strain in the visual system.
b. Minimise the use of prescription glasses helps.
c. Substituting the overpowered glasses with
the Eyewear or stepped-down glasses also helps whenever it is safe and appropriate.

6. How do we know my vision has improved?
a. The world has become super-sharp, and your existing pair of glasses feels over-powered and may even cause a headache.
b. You can also use a Snellen Eye Chart to measure your vision
improvement.
c. You should consider using your previous pair of lowered-powered glasses or have the lenses stepped-down.

7. What is model S, M, L and H?
a. They indicate the different frame sizes for different face shapes and width
b. S = XSmall (kids), H=Small, M=Medium, L=Large
c. The pin-hole plastic in all of them are the same. There is no lens or prescription specification for different degrees of myopia, astigmatism or presbyopia.

8. What are the Free Eyecharts?
a. A Snellen Eyechart will be made available for all Vision Therapy Eyewear customers so that vision improvement can be easily measured at home/work daily
b. A Near chart for presbyopic customers will also be provided
c. The charts are to be self-printed by customers (pdf file which can be printed on LTR/A4 home/office printers)

9. What is the relationship between Vision Therapy Eyewear and The Bates Method?
a. The Bates Method is a 85-year-old eye-mind training program where regaining perfect vision is possible without the use of drugs, surgery or special equipment.
b. Going without glasses and training the mind-eye to see naturally is facilitated by the use of the Eyewear (sharper vision without prescription glasses). Glasses, as taught by Dr Bates, is part of the problem.
