Just like the frame of your eyeglasses, your lenses also play an essential role in determining how happy you are with your eyeglasses. Buying a lens is not an easy task as you can easily get confused with so many options available.
Why is it Important to Choose Right Lens For Your Eyeglasses?
When you purchase eyeglasses, the frame you choose only impacts your appearance but the lens you choose impacts four different factors: comfort, appearance, vision, and safety. Most people make one common mistake because they don’t spend enough time choosing the right lens and coatings for their glasses. As a result, they face discomfort when they wear their glasses, and their eyes get tired just after a few hours of wearing lenses.
This article will give you a basic idea about eyeglass lenses so that you can wisely choose which lens suits you the best.
Different Materials of Eye Lenses and Their Benefits
Glass lenses have been used for vision correction for quite a long time. In the early days, all lenses of vision correction were made from glass. Although they are exceptionally good at correcting vision-related problems, they are very heavy and easily breakable. Thus, glass lenses are not widely used in eyeglasses, but some people prefer to have a glass lens in their prescription glasses.
The first polycarbonate lens was made for safety glasses in the early 1970s. Today polycarbonate lenses are trendy all over the world. It is more lightweight and more impact resistant as compared to CR-39 plastic. This is the reason that polycarbonate lenses are much recommended for kid’s eyewear.
In 2001, a similar lightweight eyeglass lens material was introduced known as Trivex. It had identical impact-resistant properties the same as polycarbonate.
In the past few years, people started to prefer more thinner and lightweight lenses. Therefore eyewear manufacturers introduced a new material that was 60% lighter and thinner than the standard plastic lenses.
What Kind of Lens Coating Should You Choose?
Once you have chooses the right material for your lens, now it is time to select the suitable coating for your lenses. If you want to have comfortable, good-looking, and durable glasses, then you should consider the following treatments for your lenses.
All plastic materials used in eye lenses are more prone to scratches and abrasions than glass lenses. It is because they are soft and lightweight. Although the plastic lenses are more impact-resistant, they need to have an anti-scratch coating on them; otherwise, you will see a lot of scratches on your lenses. When an anti-scratch coating is applied to your lenses, it makes them almost scratch-resistant and adequate for durability.
Anti-reflective coating improves the quality of your lenses and makes them better. It eliminates the reflection on your lenses that affects your contrast and clarity. They also make your lenses nearly invisible. It allows you to make better eye contact with others, and you do not get distracted due to reflection, especially when you are driving during nighttime.
You need to have an anti-reflective coating, especially if you choose to have high-index lenses. The refractive index of these materials is much higher, due to which they reflect more light. In some cases, these lenses can reflect 50% more light as compared to ordinary plastic lenses.
If your eyes are exposed to UV light for long time intervals, you can face several eye-related problems. So, it is important to protect your eyes from UV radiation from your childhood. If you choose polycarbonate or high index lenses, then they already have 100% UV light protection. But if you choose regular CR-39 plastic lenses, then you need to have an additional coating for UV protection.
If you add photochromic coating on your lenses, they will automatically darken in UV light or high-energy visible light rays. When you move indoors, they automatically start fading and become clear.
Blue Light Protection Coating
It is scientifically proven that blue light is harmful to our eyes. So, if you use computers and electronics for extended time periods, you must have an anti-blue light coating on your lenses. It will help you to filter blue light and reduce its harmful effects on your eyes.
