*For existing customers who have a record with us, you can select the option 'Follow Prescription' and we will issue you based on your last purchase/record with us. If you are not, you need to get your eye-check and contact lens fitting done with our optometrist at W OPTICS. You may still place your order first and we will contact you soonest to arrange an appointment. Disposable contact lenses are medical devices in Singapore and patients are subjected to an eye examination.
