Contact Lenses Contact lenses are listed by the Health Science Authority of Singapore as medical Devices. It is therefore only available on prescription by Optometrist and Medical practitioners. Every contact lens importer , must apply for a license to bring in contact lenses into the country. This ensures that contact lenses imported are of high quality and comply with safety standards. There Are Two Components To Purchasing Contact Lenses. The Contact Lens And The Professional Service. The Purchase To ensure you continue wearing your contact lenses safely, both these components must go hand in hand. It is very important to safeguard yourselves from fake branded contact lenses by buying from reputable contact lens practices. I say this because we have had an occasion where fake lenses were identified and confiscated by authorities here in Singapore.
