Glasses Lens Technology, What You Need and What You Don’t

When buying eyeglasses, choose the best frame and lens to suit your needs. Eyeglass lenses are available in different materials. The lens material does not alter the corrective power but can affect comfort and function. Lenses have various lifestyle and cosmetic benefits. It is essential to choose the right lens type for your eyeglasses. 

Choosing Eyeglass Lenses 

If your prescription changes, you need to get new lenses. You can change or replace your eyeglass lenses without getting a new frame. Ensure a professional does the replacement to avoid damaging the lens or frame. There is no single eyeglass lens that is ideal for every person. 

When shopping for new eyeglasses, consider the lens material that works for you. The choice will depend on various factors, including your vision correction requirements, lifestyle, and budget. Choose the best coatings for your environment and vision needs. 

Eyeglass Lens Technology 

Technology advancements have led to the production of highly functional and durable lenses. From using mainly glass, manufacturers now use high-quality plastics. The new lenses are lighter, thinner, and more scratch-resistant, making them more attractive. They do not break easily while allowing treatments to help shield the eyes from glare and UV light. The new lenses correct vision much better than old plastic and glass lenses. 

Eyeglass Lens Materials

When buying eyeglasses, opt for the best lens material. You have various options, including the following:

• Hi-index lenses. Made from special plastic, these lenses are much thinner than regular ones. The lenses are light and comfortable. They usually cost more than regular lenses
   

• Polycarbonate lenses. They are thin, light, impact-resistant, and usually have built-in UV protection. They are ideal for sports and safety eyewear
   

• Trivex lenses. The lenses are similar to polycarbonate, but they provide higher-quality vision. The rigid material makes the lens ideal for rimless frames
   

• Aspheric lenses. The lens design is flatter, reducing the bulging effect common with regular lenses. The curves reduce distortions, improving peripheral vision

Choosing Eyeglass Lens Features 

Consider features that will make your eyewear more functional and comfortable when choosing lenses. They may not be essential, but they are helpful. The features include:

• Antireflective coatings

• Scratch-resistant coating

• Ultraviolet (UV) protection

• Photochromatic lenses 

• Polarized lenses

What You Need and Don't Need 

The lens technology you choose will depend on your vision goals. Some eyeglass lens features are necessary, such as UV protection, but others are optional. You can choose optional lens enhancements for your eyeglasses. 

Hydrophobic lenses repel water, which helps prevent smudging. Anti-fatigue coatings are ideal for individuals who want to avoid eye fatigue. Blue light-blocking lenses are ideal for those who spend hours using computers. 

Tinted lenses and mirror coatings are more about appearance than function. If you have age-related vision problems, you can get multifocal eyeglass lenses. Your eye doctor can help you choose the best lens for your needs. Schedule regular eye exams to check your prescription and keep your eyes healthy.
