Contact lenses are a great way to enhance your vision and are often so comfortable that users forget they are wearing them. Unfortunately, while contact lenses are reliable, they are not immune to issues. If you don’t always keep a spare pair of contacts around, consider the following scenarios:

Traveling

You’ve spent months planning and hundreds or thousands of dollars booking flights and accommodations. Now imagine you’re experiencing the trip of a lifetime in another country, only to have an issue with your contact lenses. What happens if you lose or rip a contact lens on vacation? If you wear daily contact lenses this might not be an issue, but imagine a monthly or fortnightly wearer that only brought one pair for a week-long trip.

If you lose a contact, you will need a prescription to replace the lost or torn lens. That means if you don’t have a spare pair, you could be in trouble. Imagine missing out on some amazing sightseeing because you only have one contact, or having deal with the hassle of wearing glasses for your entire trip. Truthfully, even overnight trips shouldn’t be an exception. You should always pack a spare pair of contact lenses when you travel, no matter how short or long the trip.

Driving

Imagine that your work day is ending and you hop in your car ready to head home. You’re about to pull out of the parking lot when something happens—either you get debris in your eye or your contact rips—and now you are unable to see well. This might not affect contact wearers with lighter prescriptions, but some wearers will have a very difficult time seeing. It is extremely dangerous to drive with impaired vision, not only for you, but also for the other drivers on the road. There is a reason you must take an eye test before being granted a driver’s license and this is a major reason to always have a spare pair of contacts. It is always a good idea to keep a spare set of contacts in your car at all times just in case.

Sports

When it comes to vision correction, athletes prefer contact lenses over glasses. Championship games don’t come around every day and you want to prepare for them as best you can. There’s no point in spending hours prepping in practice and running through game tape, if the big day comes and your contact rips at the most inopportune time. That is why you always want to have a spare set of contact lenses on hand, no matter how big or inconsequential the contest is.

Lens Issues

As reliable as they are, contacts are not immune to ripping or tearing. Imagine heading into an important work meeting or big exam and having an issue with your contact lenses? How about at night while you’re watching your child’s school musical or play?  Truth be told, you never know when you are going to have an issue with your contact lenses, which is why you should always have a spare pair handy.
