Wearing contact lenses that have expired or surpass the recommended wearing time can have severe consequences for your eye health. It is vital to prioritize safety and adhere to the instructions provided by your eye doctor and the lens manufacturer.
Even if you diligently clean and care for your contact lenses, using expired ones can significantly increase the risk of eye irritation, infections, and corneal abrasions. When you come across a batch of expired lenses or consider wearing daily disposable lenses beyond the recommended duration, it is essential to think twice.
If you experience discomfort or notice any eye changes while wearing lenses, you must replace them promptly with a fresh pair. If any eye discomfort or issues persist, seeking professional assistance from an optometrist or eye care specialist is highly recommended.
Bacteria On Your Contact Lenses
One of the reasons contact lenses have expiration dates is to prevent the accumulation of bacteria on the lenses. Contact lenses can act like sponges, absorbing bacteria, dust, and allergens. Over time, bacteria can multiply, leading to infections that can cause corneal ulcers and potentially damage your vision.
Our Eyes Need Oxygen
Expired contact lenses also pose a concern regarding oxygen permeability. As lenses age, they become less permeable, making it more difficult for oxygen to reach your eyes. Inadequate oxygen supply can lead to eye swelling, redness, and irritation.
Suppose you experience these symptoms or require an updated contact lens prescription. In that case, it is important to contact an optometrist or eye care professional for guidance and evaluation.
Ensuring the safety and health of your eyes should always be a top priority. By following the guidelines your eye care professional provides and avoiding expired contact lenses, you can maintain clear vision and minimize the risk of complications.
Conclusion
In conclusion, it is crucial to prioritize your eye safety and avoid wearing expired contact lenses or exceeding the recommended wearing time. Proper care, regular eye check-ups, and adherence to the instructions provided by your eye care professional are essential for maintaining good eye health.
If you need an eye exam or are looking for new eyeglasses, consider visiting an optical store like Westpoint Optical, where you can find quality frames that suit your style and preferences.
