5 Signs You Need A New Eyeglass Prescription

Est. Reading Time: 5 mins

Changes in your vision happen all the time. There are instances where the changes can pass and are treated simply with a little bit of rest. If you’ve ever stayed up late and felt your eyes having trouble focusing you can attest to this momentary poor vision. 


Lack of sleep, stress or eye strain caused by visual fatigue (picture long days on a computer) can temporarily affect how well you’re seeing. This makes it difficult to determine if your vision problems are a case of tired eyes or if it may be time to book an appointment with your Eye Care Professional.


Luckily, there are some early warning signs to look out for that could be directly related to changes in vision.  Although the sudden loss of vision is possible, the changes are usually gradual and you may not even notice right away. If you’re constantly experiencing any of these symptoms, it may be a good indicator that it’s time to contact your Eye Care Professional. They can give you greater insight into the health of your eyes and may recommend an adjustment in your prescription.  

1. Blurred Vision

Right off the bat, if you experience unexpected blurriness in vision when you’re already wearing glasses; there’s a good chance your vision has changed. Your glasses are designed to correct your deficiencies in seeing clearly and if they’re not working you may need to adjust the lens power.


Booking a comprehensive eye exam is strongly recommended when symptoms of blurriness in vision occurs. A comprehensive eye exam will not only help you in getting the appropriate lens correction but it may identify any underlying eye health issues at the earliest stage. 

 

2. Squinting

 

Squinting is a natural way of improving focus and clarity in your vision. You may not realize how often you’re actually squinting mostly because it happens automatically as you need more clarity. 

However, excessive squinting can be an indicator that your vision has changed. If you find yourself squinting every time you’re trying to read a road sign, use a computer/laptop or reading a book then a change may be necessary for your eyeglass prescription

Excessive squinting means you’re constantly straining your eyes. This eyestrain will worsen over time and could cause your clarity in vision to decline. It may require a stronger prescription to correct your vision problem in the future. 

3. Eyestrain

Eye strain or the feeling of your eyes hurting/being tired can be attributed to multiple factors like the amount of sleep you get or even seasonal allergies. However, in cases where eyestrain is persistent; it could signal a change in eyewear is required. Either with a new prescription or a different type of prescription lens altogether.

If you feel your eyes are hurting or tired when you have glasses on but then it subsides when you take your glasses off, consult with an Eye Care Professional as soon as possible. This is a clear indicator you need an adjustment in your prescribed power. 

4. Headaches

Many people may not experience noticeable changes in their vision but they will report an increase in headaches. Headaches are usually one of the first signs of needing an updated eyeglass prescription.

 People who are nearsighted (myopia) tend to experience headaches at the front of the head or right above the brow line. Meanwhile, those who are farsighted (hyperopia) will get headaches when reading or looking at things up close for extended periods. 

5. Difficulty seeing at night

People may have a “clear” vision in the daytime but begin to face challenges as it gets darker in the evening. This is due to the fact that there is more available light during the day. Your pupils are smaller and provide a greater depth of field in the daytime.

At night, however, your pupils begin to dilate to take in more light. This makes blurriness caused by vision deficiencies (hyperopia, myopia, astigmatism, and presbyopia) become more apparent. 

The bottom line

Although experiencing one or more of these symptoms may not always translate into a problem in your vision, It’s always recommended to schedule regular eye exams. Your optometrist or ophthalmologist can monitor the health of your eyes. They will determine if your current prescription still works as well as screen diseases or eye conditions.
