MY PERSONAL OPINIONS ONLY :-
In the western countries this is what happens as described above. But in Malaysia, we are a developing country, and the rules are not as strict as in the western countries. During the 60″s and 70″s there were not many optical shops run by qualified optometrist.
According to Google, the “World Optical Company” was established in 1934 by Mr. Johnson Lam Chih Yeah in Penang. I think it was in Leigh street. He was an American trained Doctor of Optometry.
Another was Shu Tong Mow also founded in the 1930″s by a first-generation migrant from Shanghai. There was also Malaya Optical founded in 1957.These were the earlier pioneers of the optical industry in the then Malaya.
I remembered when I was 15 years old, I went to the “The World optical Company” to make my first spectacle. in Sungai Patani. They did not open a full shop or branch there. They only rented the back portion of a shop lot in Jalan Ibrahim , somewhere near the clock tower. Furthermore, they did not open everyday but only 3 days a week and that was only in the afternoon. It costs my parents Rm18.00 for a plastic frame and a glass lens. It was a big amount in those days.
During those years there were not many optical shops and moreover not many people were shortsighted like the present generation. If you live in a small town, you will have to go to Penang to make an eyeglass.
There were also not any readymade glasses like those found abundant today. China at that time was behind a bamboo curtain…
During those times, one can only get an optometry degree from the U.K or Australian universities. It would cost a hand and foot to go there. There were no courses offered in the local universities then. The authorities did not pay much attention to this field, and many optical outlets began to mushroom throughout the country. At that time almost 80% to 90% of those optical outlets were run by non qualified opticians.
When the authorities took notice of the situation, they granted a grandfather’s license for all those who opened their optical shop and who were members of the optical association. The authorities later tighten the rules and those with a degree from a recognize universities can only open an optical shop. Still, there are many optical shops opened in the rural or semi rural areas without a license.
The optometrist has a green certificate while the opticians is blue in colour .
