The purpose of having prescription eyeglasses is to optimize your vision. If they no longer do this, several things may happen. You lose your ability to see well, and vision issues can deteriorate rapidly. For this reason, you must know what to look for when reviewing your prescription.

Several signs can point to this before booking an appointment with your eye doctor. They include:

Recurring Headaches

Constant headaches are among the clear signs of change in your vision. Noticing these slight changes is not easy. Most people tend to overlook them. The truth is that your brain recognizes these fluctuations. Once it gets an alert of these changes, it tries hard to correct them. The process disperses large portions of energy, wearing the brain out and causing headaches.

Eye Fatigue

Eye fatigue can result from several factors. Some include seasonal allergies, insufficient sleep, illness, or focusing on something for too long. However, if tiredness lasts for more than 48 hours, there could be a change in your vision. Visit your eye doctor for recommendations on what to do. They may retest your eyes and prescribe a new pair of eyeglasses.

Sensitivity to Light

Bright light can make you squint or want to shelter your eyes. But if pain exists, you need to review your eyeglass prescription. Book an appointment with your optometrist since eye sensitivity can be a symptom of several things. They can be a symptom of eye infections, overworking, or chronic vision issues that need immediate attention.

Squinting is something most people do involuntarily throughout the day. Without addressing the issue, it can result in more damage to your eyes. It ends up straining the eye, exacerbating your vision issues. If you notice this happening more often than usual, it may be time to update your prescription.

Blurry Vision

Blurry vision is the most noticeable sign of a significant change in your vision. Fluctuations in eyesight are not often consistent and are easy to overlook. It is also natural to have a different prescription lens for each eye. You may notice that one eye requires constant reviews while the other remains the same. The changes can either be severely disorienting or subtle.

Old Eyeglasses

Having the same eyeglasses for multiple years is a valid reason for getting a new pair. Your eyes typically deteriorate over time. The prescription lenses have an expiry date, just like any other product. Eye doctors recommend that spectacles should not reach their second birthday. It is imperative to have an annual eye exam. Other than checking the health of your eyes, they also confirm whether your eyeglass prescription is current.

Eyeglass prescriptions that are out of date make vision problems worse. Your eyes strain more, resulting in unnecessary pain, discomfort, and damage. Yearly updates on your spectacles help sustain good eye health.

You may also need new glasses when they have scratches on the lens or are tedious to clean. Even minute nicks can compromise your vision in ways you do not know. They can also cause a strain on your eyes.
