I notice lately that an increasing number of youngster, in the streets of hong kong, are putting on spectacles with no lenses. It prompts me to think how people who need spectacles to aid their vision, want to do without them. And yet, there are people who do not need spectacles put them on as fashion.
Maybe one day, spectacles would be part of being trendy. People might keep a few pairs at home and even match spectacles with their daily wears.
If that is the trend, can consider a new business model. Trendy Specs.
