Headaches experienced while wearing glasses are a common concern, often signaling that the eyes and brain are working harder than they should to process visual information. These headaches can arise from various factors, ranging from the initial adjustment to a new prescription to issues with existing eyewear. Understanding the underlying causes helps address discomfort and maintain visual comfort.
Headaches from New Glasses
When you receive new glasses, especially with a different prescription, your eyes and brain undergo an adaptation period, which can lead to temporary headaches and eye strain. For instance, a significant change in prescription or the introduction of progressive lenses, which have varying focal points, can initially cause blurry vision, dizziness, and discomfort due to peripheral distortion. The brain needs time to learn how to navigate these different zones and interpret the new way light enters the eyes.
The precise measurement of your pupillary distance (PD), the space between the centers of your pupils, is crucial for new glasses. If the optical center of the lenses does not align correctly with your pupils, your eyes may have to work harder to focus, leading to visual distortions, eyestrain, and headaches. Incorrect frame fitting, where the glasses sit too high or low, or are too tight, can contribute to discomfort and headaches. These adjustment-related symptoms should resolve within a few days to two weeks for single vision lenses, though progressive lenses may require up to two or three weeks.
Headaches from Existing Glasses
Headaches can develop from existing glasses, indicating issues that have arisen over time. An outdated prescription is a frequent cause, as vision changes gradually, forcing the eyes to strain to compensate for inadequate correction. This increased effort can lead to eye fatigue and tension headaches, often described as a dull ache around or behind the eyes. These headaches may become more noticeable later in the day or after prolonged visually demanding tasks.
Ill-fitting frames can cause headaches, even if they once fit well. Frames that are too tight can put pressure on the temples or nose bridge, while loose frames that slip down can force the eyes to constantly adjust their focus. Damaged lenses, such as those with scratches, can distort light, making it harder to see clearly and leading to eyestrain and headaches as the eyes compensate for blurred or distorted images. Over time, even the coatings on lenses can degrade, potentially contributing to visual discomfort.
Immediate Steps for Relief
If you experience headaches while wearing your glasses, several immediate steps can help alleviate the discomfort. Taking short breaks from wearing your glasses can provide temporary relief for your eyes. Resting your eyes for about 15 minutes in a darkened room can help them relax.
Performing simple eye exercises can reduce strain. The 20-20-20 rule is a practical method: every 20 minutes, look at an object 20 feet away for at least 20 seconds. Blinking frequently can help lubricate the eyes, especially during prolonged screen time when blinking naturally decreases. Gently placing warm palms over closed eyes for 30 to 60 seconds, known as palming, can soothe tired eye muscles. Ensuring your lenses are clean and free of smudges or scratches can immediately improve visual clarity and reduce eye strain.
When to See an Eye Doctor
While temporary discomfort with glasses is common, persistent or severe headaches warrant professional attention. If headaches continue for more than a few days to two weeks, especially after getting new glasses, it is advisable to consult an eye doctor. Headaches that are severe, occur frequently, or are accompanied by other symptoms such as blurry vision, double vision, nausea, or dizziness, suggest a comprehensive eye examination is needed.
An eye care professional can accurately diagnose whether the issue is an incorrect prescription, improper pupillary distance, ill-fitting frames, or an underlying eye condition. Regular eye exams, typically every one to two years, are important for detecting gradual changes in vision that might lead to headaches. Only a qualified professional can make the necessary adjustments to your prescription or frames, or identify other potential causes for your discomfort.
