Eyewear guide for high myopia Part 6 lens coating

From my experience with high myopia glasses, I've learned that the lens coating is both a crucial and delicate feature. Lens coatings improve clarity and reduce reflections but are highly sensitive to heat and chemicals. For instance, exposing lenses to hot air from hairdryers or leaving them in a hot car can cause irreversible blistering or peeling of the coating. I've found that even quick moments, like placing glasses on a bathroom counter where a hairdryer is used, can lead to damage. To keep your lenses in top condition, I always store my glasses in a dedicated microfiber case and clean them with neutral lens solution and a soft cloth. Avoid harsh chemicals or alcohol-based cleaners because they can strip the coating. Never rinse your glasses with very hot water and keep them away from steam during showers. It's surprising how common these pitfalls are, yet the damage is permanent, often necessitating expensive lens replacement. Additionally, scratches are unforgiving and easily caused by friction with hard surfaces or improper cleaning methods. I recommend gently rinsing your glasses with water before wiping to avoid grinding dust particles against the lens surface. Lastly, avoid exposing glasses to acidic or alkaline liquids which could corrode the coating. In summary, protecting your lens coating through careful handling and mindful storage is essential to maintaining optical quality and comfort when wearing glasses for high myopia.
