You can tell your optometrist that your last trial pair did not fit properly and bothered your eyes. You could say that your current contacts are prone to rips and tears and you want to find a more durable lens. You are interested in testing out prescription color contact lenses to freshen up your look and want a trial pair. You find the daily contact lenses you currently use a bit of a hassle and would like to test out the two-week lenses (or vice versa).
It works best with contacts that are at least two-week wear. Think about it — is it really worth it to do a round-robin with seven different opticians for one free trial pair of dailies?
For example, Acuvue often gives out free trial lenses. [5] X Research source
For example, some retailers will offer a promotion for a buy one and get one free on contact lenses. Although this will require a payment you will still receive some contact lenses for free.
Remember, however, that contact lenses are considered medical devices and must be prescribed by a licensed physician. The manufacturer will need your prescription to do this.
