If you decide to give this technique a try, follow these steps to apply Vaseline effectively:

Clean the Lenses: Begin by thoroughly cleaning your lenses using a microfiber cloth and lens cleaner. This step ensures that any existing dust, dirt, or smudges are removed before applying the Vaseline.
Apply a Small Amount of Vaseline: Use a cotton swab or your fingertip to apply a tiny amount of Vaseline to each lens.
Spread Evenly: Use a soft cloth to spread the Vaseline in a thin, even layer across the lens surface.

Wipe Off Excess: Gently wipe away any excess Vaseline with a clean, dry cloth until the lenses are clear.
Inspect the Lenses: Ensure that the lenses are clear and not greasy before using the glasses.
Alternatives and Other Practical Uses
If Vaseline is not suitable for your glasses or personal preference, there are alternative methods for preventing lens fogging and reducing scratches, such as anti-fog sprays and lens cleaning wipes specifically designed for eyeglasses.

However, Vaseline remains an accessible and cost-effective solution that can be used for multiple purposes around the home. Its versatility extends beyond eyeglass care, serving as a skin moisturizer, lubricant for stuck zippers, and even as a protective barrier for minor cuts and burns.

Conclusion
Applying Vaseline to your eyeglass lenses is a surprisingly effective method to address common problems like fogging, scratches, and smudges. While this simple solution may seem unconventional, it has practical benefits that are easy to overlook in favor of specialized, often expensive products. This technique reflects a blend of traditional wisdom and modern-day needs, showcasing how everyday items can still solve common problems.

That said, it is important to consider the type of lenses you have and any coatings they may feature before using Vaseline, as well as testing for any personal sensitivities. If done properly, this low-cost solution can extend the life of your glasses and reduce maintenance efforts, offering a practical alternative for eyeglass care.
