reduce the cost of corrective eye wear

If you've had your current prescription glasses for more than two years, it's time to get your vision checked. Prescription lenses aren't intended to last forever. Even if you think your vision is the same as it was when you last had your vision tested, it might have undergone changes that you're not aware of. Even minor vision changes can cause problems if you're wearing the wrong glasses. Here are four signs that your current prescription isn't working anymore. If you recognize any of the signs, it's time to have your vision tested again.

You Rub Your Eyes More Often

Wearing the wrong prescription lenses can really tire your eyes out. Once your eyes are fatigued, they'll let you know it. If you've been rubbing your eyes more often or taking your glasses off to rest your eyes, they're trying to tell you something. If you're wearing old prescription lenses, your eyes are probably trying to tell you that they need a change.

You're Getting More Frequent Headaches

If you're wearing the wrong prescription lenses, your eyes are straining to see properly. In fact, to your eyes, wearing the wrong prescription is the same as wearing no glasses at all. The strain that you're putting on your eyes while wearing the wrong prescription is going to lead to an increase in headaches. If you've been experiencing more frequent headaches, it's time to have your vision checked. The glasses you're wearing could be putting too much strain on your eyes.

You're Experiencing Nausea or Dizziness

You might not realize this but your eyes see two different images. Each eye processes the image it's seeing, and then both eyes process it together to give you the image that you see. If you have different vision problems in each eye, you'll need glasses that correct each eye individually. If your prescription is outdated, your eyes are trying to process two images through lenses that are incorrect. The end result may leave you feeling nauseous or dizzy. If you're beginning to experience either of those symptoms while you're wearing your glasses, you need to have your vision tested. Your prescription may have changed over the years.

Your Vision Seems Cloudy

If your vision appears cloudy when you put your glasses on, chances are good that your vision has changed since the last time you visited your optometrist. You could have developed either cataracts or glaucoma, both of which can cause cloudy vision. To identify any new vision problems, you should schedule an appointment with an optometrist at facilities like San Juans Vision Source.
