Hi, it is worthwhile to make a trip to Holiday Plaza at JB to make ur prescription glasses. All the optical shops r qualified like those in S'pore. U can request to see the opticians' qualifications and certificates to practise.
I have found out that City Square and KSL at JB quote higher prices due to their higher rents. Remember the high price we paid for a product goes to pay the shop rent mainly. So a gd location and posh mall demands high rents.
Let me share some inside information regarding the makeup of a pair of prescription glasses from a friend who is in this business. The price quoted is about 5 times. 1 part is the cost and the other 4 parts is to cover the rent, labour, other liabilities and profit. So if u r quoted 200 dollars for ur pair, the real cost is about 40 dollars.
Walk around Holiday Plaza and check up the prices of the various shops. Last year a friend made one on the spot at Holiday Plaza after considering the price she paid for a similar pair in Singapore. She said it is 30 percent cheaper. I am sorry I cannot recall the shop name.
If u have further questions u may pm me.
