If you know your exact eye power, all you need to do is submit your prescription at eyemyeye.com once your order is placed. If not, visit your local optician to know your power & then place the order. Remember, the numbers on your Prescription card can look a bit complicated. Make sure you fill in your power details correctly or you may also connect with our customer care experts who will help you with the same. You can also learn how to do it yourself with our easy Prescription Guide.
