Why You Should Never Just 'Top Off' Your Contact Lens Case With Fresh Solution

For those with less-than-perfect vision, rinsing and storing contact lenses each day might be a familiar routine. But as the American Academy of Ophthalmology (AAO) points out, few people actually clean their lenses properly.

One investigation by the Centers for Disease Control and Prevention revealed that 99 percent of people who wear contact lenses exhibit at least one behavior that puts their eyes at risk for irritation or infection. There are more than a dozen things that contact lens wearers should never do—from swimming in contacts to using the same case for months or years—but the dangers of wearing lenses that have been left to soak in old contact lens solution are often overlooked.

People who wear contacts sporadically might have a habit of keeping their lenses stored in a case for days or weeks at a time, only to pop their lenses in when they need them without ever changing the solution. Even if you rinse your lenses with multi-purpose immediately prior to inserting them, the AAO says this is still a bad idea.

"Disinfecting solutions lose their efficacy over time, leading to microbial overgrowth in the case and on the lens," the AAO said in a statement. If you're going to store your lenses for a few days, be sure to swap out the solution the night before you wear them in order to disinfect the lenses and remove all harmful bacteria. That could be as often as once a day if you wear lenses regularly.

The same guideline applies to "topping off" whatever old solution remains in your contact case with a squirt of fresh solution. It seems like a cost-saving measure, but you may end up spending more on co-pays at the doctor's office to treat an eye infection.

And yes, contact solution does go bad, so if you have any travel-sized bottles lying around, check the expiration date before you wind up with an eye infection on your next vacation.

This Innovative Cutting Board Takes the Mess Out of Meal Prep

There's no way any of these ingredients will end up on the floor.

Transferring food from the cutting board to the bowl—or scraps to the compost bin—can get a little messy, especially if you’re dealing with something that has a tendency to roll off the board, spill juice everywhere, or both (looking at you, cherry tomatoes).

The TidyBoard, available on Kickstarter, is a cutting board with attached containers that you can sweep your ingredients right into, taking the mess out of meal prep and saving you some counter space in the process. The board itself is 15 inches by 20 inches, and the container that fits in its empty slot is 14 inches long, 5.75 inches wide, and more than 4 inches deep. Two smaller containers fit inside the large one, making it easy to separate your ingredients.

Though the 4-pound board hangs off the edge of your counter, good old-fashioned physics will keep it from tipping off—as long as whatever you’re piling into the containers doesn’t exceed 9 pounds. It also comes with a second set of containers that work as strainers, so you can position the TidyBoard over the edge of your sink and drain excess water or juice from your ingredients as you go.

You can store food in the smaller containers, which have matching lids; and since they’re all made of BPA-free silicone, feel free to pop them in the microwave. (Remove the small stopper on top of the lid first for a built-in steaming hole.)

Not only does the bamboo-made TidyBoard repel bacteria, it also won’t dull your knives or let strong odors seep into it. In short, it’s an opportunity to make cutting, cleaning, storing, and eating all easier, neater, and more efficient. Prices start at $79, and it’s expected to ship by October 2020—you can find out more details and order yours on Kickstarter.
