In general, plastic single vision lenses will last around 2 years while glass lenses typically last 3-5 years. However, individual situations vary - it's important to monitor vision and glasses condition regularly rather than waiting too long between replacements. Replacing glasses before visual issues arise helps maintain clear sight. Consult your optometrist if unsure.

An informal survey showed that for many consumers, choosing eyeglasses is as casual a decision as picking socks. However, unlike socks where quality is apparent through touch, there is asymmetric information when buying glasses. Customers rely heavily on recommendations from optical store or clinic staff who casually throw around technical terms to confuse buyers. These terms can relate to brand, price, materials, optical design, UV protection, blue light blocking, digital lenses and more. This article focuses on one frequently mentioned term - optical design.

When we are used to wearing glasses every day for work and life, have we ever seriously thought about the relationship between lenses and our glasses, and how lenses correct our vision? Today we will unveil the mystery of how things work, discover how glasses improve vision, and what are the scientific principles behind their design? Let’s break down some key concepts in optics so we can better understand this marvel of medical technology.

As humans, vision is an important sense that our lives rely on, and clear vision is what we have always pursued. But when did lenses appear in our lives, and what is the history behind lens technology? While my early frames felt clunky and simple, today's lenses are thinner, lighter, and can even correct problems like astigmatism that would have been unimaginable just a few decades ago. I started to wonder - how did we get from the original pair of lenses to the high-tech innovations we have today? Let’s take a look at some of the key developments over the centuries that brought clarity to the lives of many people.

Eyeglasses have become an essential tool for many individuals, helping to correct vision problems and improve overall visual clarity. One crucial component of eyeglasses is the lenses, which come in various types and designs to meet different vision needs. In this blog, we will explore the basics of eyeglass lenses, shedding light on their functions, types, and how they can enhance our daily lives.

Choosing the right glasses frame material is crucial as it not only affects the aesthetics but also determines the comfort, durability, and functionality of your eyewear. With a wide range of materials available, it's essential to consider several factors to find the perfect match for your needs and preferences.
