Why Sunglasses and Contact Lenses Aren't Typically Stored in the Same Case
Sunglasses and contact lenses are both essential items for your visual health and comfort, yet they are typically stored in separate cases. This article explores the reasons behind this common practice and provides insight into how to properly store and care for both items.
Why Sunglasses Come in Separate Cases
Sunglasses are often stored in cases that are designed for aesthetic and practical purposes. Acrylic zipper cases, for example, are popular due to their protective qualities and durability. These cases are crafted to shield sunglasses from the wear and tear that can occur during travel or storage, ensuring that the lenses remain clear and scratch-free. In addition to their protective features, these cases often have design elements that add a touch of style and sophistication.
Contact Lenses and Their Storage Cases
Contact lenses, on the other hand, are typically stored in a different type of case, designed specifically for their unique needs. The primary case that comes with your contact lenses is usually airtight, designed to keep the lenses hydrated and protected from dust and dirt. This case is made of high-grade plastic and features two separate compartments—one for the left lens and one for the right lens. An additional case made of the same material is also provided for everyday use, which can be carried with you throughout the day.
The airtight design of the primary case is crucial because it maintains the necessary moisture content of the contact lenses, helping to keep them hydrated and prevent them from drying out. This is particularly important because contact lenses can become brittle and less flexible when they lose moisture, affecting their performance and comfort. The separate compartments are also important for proper hygiene. Keeping your left and right lenses in separate compartments helps prevent the spread of germs and ensures that each lens receives its own solution, which is designed to keep the lenses free from contamination.
One-Time Wear Contact Lenses
For contact lenses that are intended for one-time wear, the situation is different. These lenses are designed to be discarded after a single use. However, even with one-time wear contacts, many optometrists still recommend using a separate case that is specifically designed for storing these lenses. This is because the lenses need to remain moist and protected from contamination until they are discarded.
Common Misconceptions
There is often a common misconception that sunglasses and contact lenses can be stored in the same case. However, doing so can be detrimental to both items. Sunglasses, particularly those made of more delicate materials like metal frames or acetate lenses, can easily be scratched or damaged by the presence of contact lenses. Conversely, contact lenses can become contaminated if they come into contact with the oils and dirt from sunglasses.
Moreover, storing contact lenses and their solutions in the same case as sunglasses can lead to cross-contamination. The airtight primary case for contact lenses is not designed to handle the additional moisture and potential contaminants that could come from storing sunglasses with them. This could potentially lead to premature drying of the lenses or the growth of harmful microorganisms.
Proper Storage and Hygiene
To ensure the longevity and health of both sunglasses and contact lenses, it is recommended to store each in its own case. For sunglasses, choose a durable and protective case that is designed to shield the lenses from dirt, dust, and accidental scratches. For contact lenses, use the airtight primary case provided with your lenses, along with a separate carrying case for daytime use.
Additionally, it is important to follow proper hygiene practices when handling both items. Always wash your hands before handling contact lenses, and never store or handle them in unclean environments. Regular cleaning and maintenance of your storage cases is also crucial to prevent the growth of bacteria and mold.
Conclusion
In conclusion, while it may seem convenient to store sunglasses and contact lenses in the same case, it is best to keep them separate due to the differences in their materials and storage requirements. Proper care and storage of both items will help ensure they continue to provide the best possible performance and comfort. Whether you are a frequent user of sunglasses or wear contact lenses daily, investing in the right storage cases and following proper hygiene practices will have a significant impact on your overall eye health and visual experience.
