The Contact Lens Rule from the Federal Trade Commission in US is our major reference guideline for the prescription checking procedure of the prescription-only devices. We may apply the mentioned checking procedure to our customers in worldwide if necessary.

For order from region other than Hong Kong, we may require customers to provide prescription from their ophthalmologist/optometrist before we ship out the orders. 

For first time customers, we may manually contact them by phone or email and request for their prescription, and we may contact the customers for further information if necessary. Customer may also email their prescription to sales@leadingbridge.com before ordering.

For existing customers, we may manually verify if their previous prescription record is still within the valid period by checking the expiration date. If the previous prescription record is out of the valid period, we may contact the customers to provide us their latest prescription record.

If you need any further information before ordering, please feel free to contact sales@leadingbridge.com.
