Wearing the wrong glasses can lead to headaches. This problem occurs when the visual system works harder to compensate for inaccuracies in vision correction. Understanding why this happens and what steps to take can help alleviate such discomfort.
How Incorrect Glasses Cause Headaches
When glasses do not provide the precise correction needed, the eyes and brain must exert additional effort to achieve clear vision, leading to eye strain. The visual system attempts to compensate for inaccuracies, causing muscles around the eyes and in the forehead to tense.
An incorrect prescription is a frequent cause of this strain. If the lenses are too strong, too weak, or if the correction for astigmatism is inaccurate or outdated, the eyes struggle to focus properly. Similarly, an improperly measured interpupillary distance, which is the space between the pupils, can force the eyes to work harder, contributing to eye strain and headaches. This misalignment means the optical centers of the lenses do not match the wearer’s pupils, creating distortions that the brain tries to correct.
The physical fit of the frames also plays a significant role. Glasses that are too tight can pinch the nose or press behind the ears, directly causing headaches. Conversely, frames that are too loose and constantly slide down the nose can disrupt the visual alignment. The position of the lenses relative to the eyes, such as sitting too high or low, can also lead to discomfort and visual challenges.
Progressive or bifocal lenses can introduce challenges if not properly fitted or measured. These lenses have multiple viewing zones, and if the reading areas are not correctly aligned with the wearer’s natural gaze, it can cause adaptation difficulties. The brain must learn to navigate these different powers, and during this adjustment period, symptoms like headaches, dizziness, and nausea can occur.
Recognizing the Signs and Finding Relief
Headaches caused by incorrect glasses are often accompanied by other symptoms. Individuals might experience persistent eye fatigue. Blurred vision, where objects appear fuzzy or unclear even with glasses on, is another common indicator that the prescription may be off. Some people may also notice double vision, dizziness, or difficulty concentrating, as the brain works overtime to process distorted visual information.
If there is a suspicion that glasses are causing headaches, schedule a comprehensive eye examination with an optometrist or ophthalmologist. During this visit, it is helpful to discuss all symptoms thoroughly, including the frequency and nature of the headaches and any accompanying visual discomfort. The eye care professional can then assess if the current prescription is accurate and if the frames are properly fitted.
Ensuring the frames are correctly adjusted can provide immediate relief. An optician can adjust nose pads and temple arms. Considering the age of the current prescription is also valuable, as vision changes over time and an outdated prescription can lead to eye strain. It is not advisable to self-diagnose or ignore these symptoms, as persistent issues warrant professional evaluation to ensure both comfort and vision health.
