Many people find themselves needing corrective lenses at some point in their lives. Today’s market is filled with features and options that can overwhelm someone that has not required glasses in the past. There a few things that you will want to consider when looking into purchasing your first set of eyeglasses.
What Are They Made From?
The main component outside of the lenses themselves are the frames that hold them. The most common materials used in frame construction are either metal or plastics. In the past, plastics offered lighter weights while metal frames were considered more durable. Advances in materials have closed the gap in these distinctions to the point that other factors play a more important role in deciding on frame materials.
Specific purpose glasses, such as safety glasses, are often made from materials such as polycarbonate. Eyewear designed for people who suffer from skin allergies like contact dermatitis will require frames made from stainless steel or even titanium.
Other construction considerations may include flexibility. Flexible frames are less likely to break. This makes them ideal for first-time users as well as children. Adding spring hinges also offer more durability by producing a less rigid frame and are often included in active or sportswear designs where the user needs flexibility.
The lens is at the heart of a pair of eyeglasses, providing the corrections needed to see clearly. Traditional lenses were made from glass, but many of today’s lenses are based on various plastics. The advantage of modern components is that the lenses are often thinner and lighter than previous generations of glasses.
Many designs provide multiple benefits based on your needs. Aspheric lenses generate greater contrast, while high-index plastics offers greater UV protection for those who spend a lot of time outdoors. An anti-reflective coating helps to reduce glare and might be ideal for those who wish to avoid eye fatigue generated by time at the computer. Age-related problems are addressed with bifocal or trifocal designs that bring smaller print into focus.
For many people, especially younger wearers, the dread of looking awkward can be addressed by the vast array of frame styles available. Frames come in a multitude of colors, inlays, and shapes that cater to a person’s personality. Just keep in mind that some designs may not work well with certain lens designs.
Keeping It All In Focus
Corrective lenses available today are far superior to those available even ten years ago. Properly fitted eyeglasses will fit comfortably and provide durability during use. Your optometrist will test your eyes to help identify the proper features to use that provide the clearest vision possible.
