How to tell if the lenses are of good quality?

In the vast world of glasses, understanding whether lenses are good quality is essential.

As for sunglasses, they are not just fashionable accessories but also defenses against the harmful UV rays, invisible and potentially harmful. Therefore, to consider them as a summer accessory is definitely a mistake, since the eyes are exposed to UV rays all year round. This is even more important in the case of children.

Now, even in the field of eyeglasses, the market offers a wide variety of prices and models, each designed to meet the needs of the individual.

Considering the vast range of proposals in the field of eyewear, it is essential to distinguish between personal taste, fashion and quality.

Let’s discover the secrets to evaluating frames and lenses together, so you can make a conscious choice.

1. Type of materials used

Choosing the perfect glasses is not always easy. In addition to fashionable frames and eye-catching colours, the type of materials used is very important to ensure that your eyes are wrapped in comfort and visual clarity.

In quality glasses, each lens material is designed to correct your specific refractive errors: myopia, hypermetropia, astigmatism or presbyopia.

The key element of different lens materials is the refractive index. The higher the index, the thinner the lens. So, lens materials are selected based on your optician’s or optometrist’s prescription, the type of frame and your unique lifestyle.

There are 3 main types of lens materials in circulation:

• glass;
• plastic;
• polycarbonate.

Glass offers a crystal clear and long-lasting viewing experience, which has the disadvantage of being heavy and less resistant to shocks. In general it can be considered a good solution for those people with very high myopia.

Polycarbonate is a thin, impact-resistant material. Attractive for those seeking duration and dynamic activities, it can be subject to possible chromatic distortions.

2. Precision and centring

The lens must also be perfect in terms of precision and centering.

The size of the frame determines both the aesthetic appearance and the functional performance of the glasses you choose.

To be sure that the frame fits perfectly with your style and needs, it is essential to understand the meaning of the number defining the caliber.

For example, a small caliber, such as 47-49, suggests glasses with smaller lenses, ideal for female or smaller faces. This option can also be suitable for high-dioptre lenses, ensuring flawless vision without compromising style and also reducing lens thickness and weight.

On the other hand, if you prefer a more masculine design or have a larger face, a larger caliber (53-55-59) is the right choice. This option lends itself well to glasses with a strong and defined cut and can accommodate drop lenses, perfect for those who want a touch of elegance without sacrificing practicality. In this case, the lenses of medium-low diopters will fit harmoniously, maintaining an elegant profile.

Always remember that investing in high quality lenses is not only an aesthetic issue, but a fundamental step to ensure you have optimal vision in the long term, blending style and functionality with maximum precision.

3. Anti-reflective coatings

If you want to maintain the clarity and sharpness of your lenses, anti-reflective treatment is the secret to flawless vision, especially for those who wear glasses every day.

Anti-reflective coating is the key to optimal vision, especially for those who spend hours in front of the computer or driving at night. Reduces eye fatigue, improving vision in every situation.

In particular, as we have just mentioned, the lenses treated with anti-reflection offer superior night vision, reducing the glare of artificial lights.

So, investing in good quality lenses, making sure they are anti-reflective and with the ideal width for your lifestyle and visual needs, is the smart choice to ensure yourself a clear and sharp vision without compromise.

Of course, to get the most benefit, you will have to be careful not to spoil your lenses by regularly cleaning them with suitable products.
