Selecting the perfect frames is just one part of the eyeglass shopping process. Equally important, if not more so, is choosing the right lens material for your prescription glasses. The material of your lenses affects not only their appearance but also their weight, durability, and thickness. In this blog, we will explore the various lens materials available and help you make an informed choice for your eyeglasses.
CR-39 Plastic Lenses: Classic and Lightweight
CR-39, also known as organic lenses, is one of the most common materials used for prescription eyeglasses. These lenses are lightweight and provide excellent optical clarity. They are a fantastic choice for those with low to moderate prescriptions. CR-39 lenses are also highly impact-resistant.
Polycarbonate Lenses: Ideal for Active Lifestyles
Polycarbonate lenses are known for their impact resistance and durability. These lenses are thinner and lighter than CR-39, making them an excellent choice for individuals with active lifestyles or children. They also have built-in UV protection, which is a great bonus for safeguarding your eyes from harmful rays.
High-Index Lenses: Thin and Lightweight
High-index lenses are designed for individuals with higher prescriptions. They are significantly thinner and lighter than CR-39 or polycarbonate lenses. This not only reduces the thickness of your lenses but also the weight of your glasses, making them more comfortable to wear. High-index lenses come in various indexes, with higher index numbers indicating thinner lenses.
Trivex Lenses: The Best of Both Worlds
Trivex lenses are a relatively new entrant to the market and offer a balance between the thinness of high-index lenses and the impact resistance of polycarbonate. They are an excellent choice if you want thin and lightweight lenses with superior impact resistance.
Glass Lenses: Classic and High-Quality
While less common today, glass lenses remain an option. They offer excellent optical clarity and scratch resistance. However, they are heavier and more fragile than most other lens materials. Glass lenses are best suited for individuals who require a very high level of optical precision.
