It would be nice if we could buy one pair of eyeglasses and wear them for the rest of your life. Unfortunately, as much as we would like to think that our current pair of glasses still allow us to see perfectly fine, they can actually be causing eyestrain and fatigue. So the question that we're left with is how often we need to change out our eyeglasses and why.

Talk To Your Optometrist

The best way to know if you need a new pair of glasses is to talk to your eye doctor about your current prescription and follow their advice about any changes you may need to make. You can ask at your annual eye appointment whether or not you should switch out for a new pair. You should also bring your old pair in with you so that your optometrist can inspect them for any damages.

Damage

As we mentioned before, damage happens with eyeglasses and could cause them to be less than effective. Some damages are subtle and can only be detected by a professional. However, if there is noticeable damage to your eyeglasses such as a cracked or scratched lens or weakened frames that is a clear sign that you need a new pair. As tempting as it may be to see past the damage and continue to wear them, it could damage your eyesight further so it is always best to replace them instead.

Subtle Eyesight Changes

The changes in your vision happen so slowly that you will often not even notice that you are struggling to see. One day you might notice that you can't quite make out the letters on a street sign or you have to struggle to read small print. That's the first sign that you should get your prescription updated.

New Eyewear Technology

The technology in eyeglasses is always evolving and keeping up with it can help you to see even better. It can adapt to your lifestyle and offer you the best possible fit for your personal needs. For example, if you are someone that works with computers a lot there are glasses that can protect your eyes against harm caused by blue light. Even if you do not need a new pair for any other reason, adopting new technology could improve your quality of life by leaps and bounds.
