The optic shop uncle told me during bmt only black coloured
specs are allowed, cos they dunwan everyone got diff colour like
very fancy like that, later some pink, some white, some blue.
The truth is that, in the past, the SAF provided needy recruits
with grants to make prescription glasses, only for its enforcement
to narrow down to plastic, black-rimmed functional frames. The
regimentation loosened with better affluence &, I suppose, 99%
of today's intake needing to wear them ~lol~
Was the uncle talking about the lenses instead, eg. sunglasses?
