Home-try on is a free service, and does not connect to purchase. The home loan glasses may be kept for five days from the day that they have arrived in your mailbox or the shipping supplier, and the customer borrowing home loan glasses commits to returning the package in the supplied return bag. The customer is responsible for ensuring that the eyeglasses are handled carefully during the time they are borrowed. If the eyeglasses are not returned in time, Nividas.com will send reminders by email. Glasses borrowed but not returned are billed with an invoice.
