How to know if your glasses prescription is wrong

 

Specsavers

During your eye test, the optometrist will check for any refractive errors and assess the type of vision correction you need. During the test, your optician will look at the overall health of the eye and record any issues. They will then create the prescription lenses needed in order to provide clear vision.

Sometimes, your eyeglass prescription can be wrong because you didn’t give accurate readings in your eye exam (especially if you’re experiencing eye fatigue). It could be due to human error from an incorrectly written prescription. It could also be because your prescription has changed over time. Just one wrong number in your prescription can dramatically change your overall vision. Any medications you are on, the quality of the measuring instruments in your eye test and your biorhythm can also all lead to fluctuations in visual performance.

If your glasses prescription is even slightly wrong, it can cause several side effects such as:

  • Blurred vision
  • Dizziness/vertigo
  • Headaches
  • Nausea
  • Worse vision in one eye while the other eye is closed
  • Eye strain

How long does it take for your eyes to adjust to new glasses?

Sometimes you will need time to adjust to a new pair of glasses. The adjustment period can sometimes take a few days, a few weeks or even up to a month. This will depend on the individual and their type of prescription.

Can glasses actually make your vision worse?

Some people believe that wearing glasses will weaken your vision. This is because some people believe that using their eyes without glasses will eventually correct their vision, but this isn’t true.

Will your eyes be ruined by wearing the wrong prescription glasses?

Although your eyes won’t be damaged by wearing the wrong prescription, it can have a negative impact on your ability to do daily tasks. You may find you have trouble driving, operating machines and concentrating for long periods of time. Imperfect vision can be irritating and distracting, even if you don’t experience some of the more uncomfortable symptoms. It’s worth going back to your optician to have your eyes checked over again.

Ensure you understand your glasses prescription

If you need glasses for the first time, it can be difficult to understand all the symbols and numbers on your glasses prescription. You should ask your optician of anything you are unsure of; you can also read our helpful guide on how to read your glasses prescription.
