As an optician, you can only guide your customer to make the right choice when it comes to choosing the lens for his or her eyewear. And so it is the optician’s duty to ensure that the customer makes an informed choice…

Choosing the right lens for the eyewear is an important ritual of the entire purchase routine that the customer goes through. After all, this decision will play a key role in deciding how happy or sad will your customer be with the purchase.

The type of lens that a customer opts for is what converts the simple eyewear into a masterpiece or the perfect vision aid. Here is a guide on important points that you need to cover while talking to your customers about the different lens options.

Not just appearance!

When buying eyeglasses, appearance should not be the only concern, because comfort, vision and safety are equally important. Choosing a good lens allows the wearer to extract the best possible performance from the spectacles. From the material to the make and the coating, several factors are taken into consideration while choosing the lens for the eyewear. In this article, we take a look at these factors and their impact on the choice of lens.

Make and material

There was a time when glass was the only option available to customers investing in spectacles. The glass lenses may offer exceptionally good optical properties, they are very heavy and could end up becoming an uncomfortable option for daily wear.

As a solution, plastic lenses were introduced in 1947. In spite of being half the weight of glass, the plastic lenses have excellent optical properties. They continue to remain a popular choice even today, of course, there are different types of plastic, all with a different set of properties. Another option is the polycarbonate lens which is lighter and significantly more impact-resistant than CR-39 plastic. However, polycarbonate is recommended as a good choice for safety glasses and children’s glasses

A newer material called Trivex was introduced in 2001 with a higher abbe index making it a good choice for progressive eyewear. There are various other variants of high index plastic lenses which are lightweight, durable and offer exceptional optics.

What kind of coating does one need?

Anti-reflection coating

This could well be the irony of optics. Any lens surface reflects light as an inherent property. So, then why ask for an anti-reflection coating. Well, very simply, an anti-reflection coating on the lens makes it easier for those who have to regularly work in varying light conditions or indulge in activities like night driving.

A high-quality anti-reflection coating consists of various layers. The interaction of these layers is what helps in reducing the reflection from the surface of the lens. Reducing the reflections of light of various wavelengths optimizes clarity of vision and at the same time reduces eye fatigue.

UV block

The rays of the sun can be harmful to the eyes, if the exposure is extensive. Opting for a lens with UV block treatment will ensure that the wearer enjoys clear and accurate vision in varying daylight conditions. However, a UV block treatment does not compensate the need for a sunglass. Another option in this category is opting for lens with photochromic treatment. In this case, the lens becomes darker when exposed to sunlight.

The right combination

Leading lens companies offer various types of lenses differentiated on the basis of their coatings. The extensive range of products includes lens with multiple coatings making it easier for customers to find something to suit their needs.

However, as an optician before you recommend options to your customers, ensure that you understand their requirements precisely. From their profession to their lifestyle, every detail will help you narrow down to the right lens options for your customer.

Some offerings by leading brands

Just like it is important to find the right coat to your business suit for that impressive style statement, it is important to find the right coating for the lens of the eyewear. Listed below are a few brands that offer various types of innovative lens coating options for eyeglasses.

Rodenstock has some good options that include: Solitaire® Protect Plus 2
