Find High-Quality Replacement Lenses for Your Glasses With These 3 Tips

Purchasing the right replacement lenses is essential, because, at the end of the day, you’ll be buying something that’s going to help improve your eyesight and allow you to feel comfortable throughout the day when doing everyday tasks.

Now, what I’ve noticed is that a lot of people tend to focus a lot more on the frame of their glasses, than on the lenses they’ll be obtaining. That’s probably because they prioritize appearance over health.

Maybe I’m wrong, however, what I would like to remind you is to never forget how crucial lenses are. If you want to be sure you’ve acquired the most suitable ones, then pay attention to these tips below.

Let’s Begin With Materials

This is for sure the first step that has to be made during this process. Long gone as the days when people had only one option when it comes to lenses. I’m referring to glass. Nowadays, the selection of lenses is much bigger, although there’s no doubt that glass lenses are still very high in demand.

However, since new sorts came into play, I would like to discuss them a little bit. So what’s at your disposal then?

Polycarbonate – Here’s a material that’s very resilient. What I like about it is the fact that it’s not going to shatter or crack easily if you accidentally drop your glasses. Besides that, they provide superior clarity which can be very essential to people who have an active lifestyle. In comparison to conventional plastic lenses, there are much lighter and come with superb UV light protection.

Trivex – Here’s a newbie when it comes to lenses. This one is made from a plastic that resembles the one that’s used to make polycarbonate lenses. This material is generally very impact-resistant, light, and thin, and is able to improve vision for some individuals.

High-index plastic – High-index lenses are capable of correcting some refractive mistakes, such as astigmatism, nearsightedness, presbyopia, and farsightedness. If by any chance you have a strong prescription, with it, you’ll be able to wear glasses that come with relatively thin, and less perceptible lenses. 

Photochromic – These are ideal for people who are obligated to wear glasses constantly. The main duties of these sorts of lenses are to safeguard your eyes from harmful UV rays and to eliminate the need for another pair of prescription sunglasses.

Polarized sunglasses – These lenses are capable of lowering glare from a surface such as water, so they are ideal for active people and drivers.

The Refraction Index

Another factor that you must take into account when it comes to this is precisely this one. It is widely known as the refractive index, which can be defined as a system of assigning a particular number to lenses based on how efficient the lenses can be when bending light as it strikes the material.

And that’s something that oftentimes puzzles people because they’re not sure how to determine that. If you do not want to make any mistakes during this process, then I would advise you to consult somebody who has enough experience and is knowledgeable when it comes to this. In a nutshell, the most important thing to focus on is the index of the material. The higher it is the slower the light movement is going to be as it moves through the lenses. This further means that less material is necessary in order to effectively manipulate light in the best possible way for the person who wears the glasses.

The Importance Of Abbe Value

So what do we know about it? It represents a number that is a good indicator of dispersion, which is also known as the dispersion index. In case you didn’t know, a lens that comes with a low Abbe value can cause a high dispersion, which can result in undesirable chromatic aberration. 

And what is chromatic aberration? It can be defined as a distortion of the picture because the lenses are not capable of concentrating on all colors onto the same focal point. This can cause eye-related inconveniences for people who are experiencing this.

Generally speaking, high index lenses provide a thin lens, however, they typically come with a lower abbe value. The higher the abbe value, the less distortion you’ll be having, and your vision is going to be much clearer. 

I know that to a lot of you, it can be quite challenging to hunt down lenses that are both aesthetically pleasing, plus provide optical clarity.

As you can see, there aren’t too many factors that you need to take into consideration when purchasing the right replacement lenses, however, if you want to make the right decision, then you cannot overlook anything that’s been mentioned here.
