Experiencing headaches or discomfort with new glasses is common. The eyes and brain often require a period of adjustment to new visual information, which can manifest as temporary physical sensations. This article explains why these sensations happen, what to anticipate during the adjustment phase, and when to seek professional guidance.
Understanding Initial Discomfort
New glasses can cause headaches and discomfort as the eye muscles and brain adapt to altered visual input. When a new prescription is introduced, eye muscles must work differently to focus through the new lenses. This change in effort can lead to muscle strain, often resulting in headaches, especially with a significant prescription change or a first pair of glasses. The brain also needs to recalibrate how it processes the newly sharpened images.
This adaptation is particularly noticeable with certain lens types, such as progressive lenses or those correcting astigmatism. Progressive lenses, offering multiple vision zones, require the brain to learn how to navigate different focal points, sometimes causing initial disorientation or a “fishbowl effect.” Astigmatism correction can alter spatial perception, leading to temporary dizziness or an off-balance sensation as the eyes adjust. Beyond prescription changes, the physical fit of new frames can also contribute to discomfort. Tight frames can exert pressure on the nose or temples, leading to tension headaches.
Typical Adjustment Period
The adjustment period for new glasses typically lasts a few days to two weeks. During this time, minor symptoms like eye strain, mild headaches, or slight visual distortions are considered normal as the visual system adapts. Consistency in wearing the new glasses helps facilitate this adjustment process.
Some individuals might experience a longer adjustment, particularly with a substantial prescription change or when transitioning to specific lens types like bifocals or progressive lenses. First-time glasses wearers may also find the adaptation period extended. Most symptoms should gradually diminish as the eyes and brain learn to work together with the new lenses.
When to Consult an Eye Care Professional
While some initial discomfort is common, persistent or worsening symptoms indicate it is time to consult an eye care professional. If headaches continue for more than one to two weeks, or if they worsen, it suggests a potential issue beyond normal adjustment. Persistent or severe eye strain that does not improve with rest warrants professional evaluation. Symptoms such as distorted vision, double vision, or significant blurriness that does not resolve should also prompt a visit, as these can indicate an incorrect prescription or a problem with the lenses.
Feelings of nausea, persistent dizziness, or a sensation of being off-balance are additional signs that require attention. These symptoms can arise if the prescription is not accurate or if there are issues with lens alignment. Physical discomfort from the frames, such as pinching or constant pressure that cannot be resolved with minor adjustments, also signals a need for professional fitting or frame modification. Follow-up appointments are important if recommended, allowing the eye care professional to assess the fit and prescription for optimal vision and comfort.
Tips for Adapting to New Glasses
Several practical strategies can help ease the adjustment to new glasses and minimize discomfort. Wearing the new glasses consistently is often recommended, especially during the initial days, to help the eyes and brain adapt more quickly. If significant discomfort or eye strain occurs, taking short breaks from wearing the glasses can provide relief, gradually increasing wear time as comfort improves. Ensuring the glasses fit properly is also important, as ill-fitting frames can cause physical discomfort and headaches; an optician can adjust them.
Avoiding immediate engagement in strenuous visual tasks, such as prolonged computer use or extended reading, can prevent exacerbating initial eye strain. Instead, gradually introduce these activities as the eyes adjust. Keeping lenses clean with a microfiber cloth and lens spray can also prevent visual strain from smudges or dirt.
