Blurry vision after wearing a sleep mask is often caused by excessive pressure on your eyes. Fortunately, this is usually temporary and easily remedied.
Understanding the Cause
The problem typically stems from a sleep mask that's too tight, applying undue pressure to your corneas. This pressure can temporarily distort the shape of your cornea, leading to blurry vision upon waking. The good news is that this blurriness is usually short-lived and resolves within a few hours to 24 hours after removing the mask. [1, 2, 3, 4, 5, 6, 7]
Solutions for Blurry Vision
- Loosen Your Mask: The simplest solution is to adjust your current sleep mask to ensure it's not too tight. Make sure it fits comfortably without pressing heavily on your eyes. [1, 4, 7]
- Buy a Better-Fitting Mask: If loosening your mask isn't sufficient, consider purchasing a new sleep mask designed for better comfort and fit. Look for masks with adjustable straps and soft, breathable materials. [1, 4, 7]
- Give it Time: In most cases, the blurriness will clear up on its own within 24 hours. Simply remove the mask and allow your eyes to rest. [2, 3]
When to See a Doctor
While temporary blurry vision after wearing a sleep mask is common, persistent blurriness that lasts longer than 24 hours warrants a visit to an ophthalmologist or optometrist. This prolonged blurriness could indicate a more serious underlying eye condition. [1, 4]
Prevention
- Choose a Comfortable Mask: Select a sleep mask made from soft, breathable materials. Avoid masks that feel constricting or uncomfortable even when loosely applied.
- Adjust Regularly: Throughout the night, subconsciously check the tightness of your sleep mask and adjust it if needed.
By following these simple steps, you can usually eliminate or minimize blurry vision related to sleep masks. Remember, prolonged or unusual blurry vision requires professional medical attention.
