you guys shouldn't buy contact lenses off the shelves or online.
IMHO, i think the reason why counterfeit contact lenses could be sold in optical shops is because of YOU PEOPLE. Optical businesses make use of your STUPIDITY and IGNORANCE to sell these lenses to you consumers.
Contact lenses are medical devices. You do not walk in to a shop and buy them OFF THE SHELF as though they are cosmetics. You have to go through a comprehensive eye examination before the optometrist choose the right lenses that are suitable for your eyes. You are not buying clothes here. GROW UP SINGAPOREANS, don't wear lenses just to look good. You have a brian, USE IT.
Getting your eyes checked every time you replenish your lens supply will ensure that eye infections get detected early and referred for medical attention ASAP. should lenses be unsuitable during your follow up visits to the optometrist, you may be asked to change the type of lenses. Just like taking medications, DO NOT BE YOUR OWN OPTOMETRIST!
We optometrists also would not know if the lenses we are selling for our bosses are genuine or not if our bosses don't tell us. So, Help us! CHECK YOUR EYES AT EVERY VISIT. SO YOU WON'T HAVE TO BE AFRAID OF CATCHING AN EYE INFECTION AND GOING BLIND JUST BECAUSE OF A PIECE OF CHINA MADE PLASTIC. AND WE CAN CATCH ALL THOSE IRRESPONSIBLE *******S RUNNING "LEGAL" BUSINESSES IN SINGAPORE.
