Around the world, billions of people rely on prescription glasses to see well. Consumers plan to spend hundreds of dollars on each eyewear purchase, while most need replacement eyewear every 1-3 years. However, it is usually not the whole pair of glasses that needs to be replaced. Rather, it’s just the lentils. Lenses may require replacement due to scratches, breaks and prescription changes. Buy replacement lenses can be done at a fraction of the cost of a new pair of glasses. If you like your current frames and want to save money, consider replacing only the part of the glasses that needs to be replaced.
Since you are only buying new lenses, you may be able to afford more sophisticated lenses than not. Replacement lenses can upgrade any frame with the latest vision technology. Whether you need bifocals, progressive lenses or high index lenses for your prescription, these are closer to your reach than you previously thought. You would no longer need to consider buying different glasses for reading and driving.
However, lenses are not limited to focal lengths. Another dimension is material; the most common types of lenses today are plastic, glass, and polycarbonate. Different lens materials can affect clarity and durability of vision. Plastic is the most affordable option, but it lacks the natural scratch resistance of glass. Glass has the greatest optical clarity, but is more susceptible to breakage than polycarbonate lenses.
You shouldn’t just rely on the lens material to provide eye protection. Lens coatings can provide additional benefits. In addition to fighting scratches, lens coatings can also provide UV protection, blue light reduction, and fog resistance. Most lenses today come with scratch resistance and free UV coatings. The former adds more durability to polycarbonate and high-index lenses in particular.
Now that you know the most common lens features, let’s talk about some more unusual features available to consumers. Color-tinted lenses may look stylish, but did you know they can also provide visual benefits? Different colors bring different benefits to the wearer. Yellow and orange tints improve contrast in low light conditions. They can make night driving easier. Brown tints can reduce the tension of nearsighted people in direct sunlight. The gray reduces fatigue and allows the lenses to function as versatile sunglasses. Blue and purple tints improve vision in foggy conditions and provide protection against highly reflective surfaces. Finally, pink (or pink) lenses improve depth and detail perception. They can also reduce migraines. For people with dyslexia, tinted lenses may cause them fewer problems than other types of glasses.
All lenses above are for regular eyewear. And the sunglasses? Sun lenses can be added to all frames, with or without a prescription. Polarized lenses disperse light rays to reduce the intensity of sunlight and glare. They provide UV protection and reduce glare, but may not be compatible with LCD screens or some windshields. Transitional lenses are lenses that darken when exposed to UV rays, combining a pair of sunglasses for the sun and indoors. However, it takes some latency to adapt to new conditions.
Let’s say you order replacement lenses. How long does it take to receive them? It can be as little as 5 days! All you have to do is ship your frames to a lab, wait for new lenses to be created and fitted to your frames, and then they will be shipped back to you. Because you’re not going through an optometrist, you can avoid the extra markup that many such stores charge. Upgrading your favorite glasses with new lenses is convenient and easy for all consumers.
