How Often Do You Need to Replace Your Glasses and Contact Lenses?

As you age, your eyes age with you, which means the prescription eyeglasses you bought a couple of years ago may no longer be the right prescription for you. In fact, wearing an old prescription can do you more harm than good. Here are some signs it’s time to ditch your specs for an upgrade.

Signs You Need New Glasses

Optometrists recommend replacing your glasses every one to three years. However, everyone is different, and there’s no hard and fast rule. Your eyesight may change so slowly that it may not be obvious you need new glasses. If objects seem blurry, or if you need to squint while wearing your glasses, your lenses are probably outdated. Wearing eyeglasses with even a slight lens error can cause tired eyes, vertigo and frequent headaches. Another telltale sign you need new glasses is if you feel relieved and more relaxed when you take them off. If you notice any of these symptoms, book a general eye exam with an optometrist to check your prescription and update it if necessary.

More Than Lenses

It’s not just your lenses you need to worry about. Over time, the temples, bridge, and nose pads on your glasses can loosen and deform. This can cause your glasses to become uncomfortable to wear as they no longer sit correctly on your face. Additionally, the frames may fall out of fashion, and you may no longer feel confident wearing them in public. These are also good reasons to update your glasses. The above tips also apply to prescription sunglasses. Another thing to look for in sunglasses is the UV protection coating on the lenses. If the coating is starting to flake and peel, your sunglasses may not protect your eyes anymore, and you should get a new pair.

When to Replace Your Contact Lenses

If you wear contact lenses, you must be stringent about replacing them. Here’s a quick guide on what you need to know.

  • Daily disposable contact lenses should be discarded and replaced every day.

  • One- and two-week disposable contact lenses must be replaced according to the manufacturer’s instructions. Set a reminder on your calendar or create an alarm on your phone to remind you to change them.

  • 30-day contact lenses must be replaced once a month. Doing it on the first of each month will make it easier to remember.

  • Overnight lenses have a lifespan of a week to 30 days.

Ask your optometrist how often you should be replacing your contact lenses based on the type of lens and your ocular health. Contact lenses need to be stored in fresh contact lens solution when you’re not wearing them.
