Can The Wrong Prescription Eyeglasses Make My Vision Worse?

Can The Wrong Prescription Eyeglasses Make My Vision Worse?

Eyes can change over time. This means your prescription can change and you need to get new eyeglasses lenses to ensure clear vision. If your vision changes but you do not upgrade your prescription lenses, your eyeglasses will not improve your vision and may even cause some uncomfortable symptoms. If you receive new eyeglasses that do not have the correct prescription, your vision may become drastically altered and cause uncomfortable physical symptoms. Wearing the wrong prescription, even over a long period, won’t actually change the prescription you require or damage your eye health, but it can still cause temporary issues that will resolve once you start wearing the correct prescription eyeglasses.

The Symptoms Of Wearing The Wrong Prescription

Wearing the wrong prescription of glasses will neither make your vision worse nor create lasting health issues. It will not actually impact your eye health at all, but it can impact your ability to see clearly and cause some uncomfortable symptoms. Once your prescription eyeglasses are updated with the correct prescription, your symptoms should resolve. Here are some common ways wearing the wrong prescription can negatively impact your vision and how that may affect you.

Blurry Vision
When you’re not wearing the right prescription or not wearing eyeglasses when you need them, your vision will be blurry. Eyeglasses are designed to improve your vision and if they aren’t properly customized to your eyes, they won’t work right. Eyeglasses function by bending light that comes through the eyeglasses lens so that it is directed onto the correct area of your eye. Because light has to hit the back of the eye (the retina) just right for a clear image to form, if the light entering your eye is not bent to your specific prescription, your eye will not be able to interpret it clearly.

Your prescription will not only alter your clarity of vision, but it may also alter your depth perception. Changes to depth perception can cause a person to feel dizzy. It is normal to feel some mild dizziness or disorientation when you first switch to a new prescription, but this should not persist past two weeks of regular eyeglasses wear. Any dizziness from a new eyeglasses prescription should not be severe; you should not be dizzy to the point of nausea or falling down. If your dizziness is severe after receiving a new prescription, the prescription may not be right.

Eyestrain And Headaches
If you are wearing the wrong prescription and your vision is blurry, you will naturally try to focus to correct for this. Constantly focusing your eyes in an attempt to see properly will create eyestrain. Eyestrain happens when your eyes get tired from intense use. When your eyes focus, it forces your eye muscles to contract. Over a long period, the eye muscles become strained and can trigger a headache. The longer or more frequently your eyes try to focus, the worse your headache will become. Along with causing headaches, eye strain can result in eyes that are sore, tired, watery, burning, or sensitive to light.

Some of the most obvious signs that you need corrective eyewear or a prescription upgrade include trouble focusing, blurry/double vision, frequent headaches, and constant squinting. A routine eye exam with your eye doctor is the best way to confirm if there are any changes to your vision.

When you have a comprehensive eye exam, your Calgary eye doctor will determine your prescription through a series of ocular tests. The eye doctor will ask you to read a series of letters that get increasingly small, called a visual acuity test. The optometrist will also have you look through a phoropter to determine which lenses make your vision clearer. After your Calgary optometrist determines your prescription, they can have it printed out for you to take with you if you would like.

To find the perfect pair of eyeglasses, there are several factors you must consider including your current eye health and visual acuity, your lifestyle, your face shape, eye/hair/skin colour, and of course your personal style. The opticians at Blink Eyewear can help you find a pair of eyeglasses that are both functional and stylish.
