Guide to NAU! Lenses

Myopia

MyopiaMyopia

WHAT IS IT?
Difficulty in seeing clearly objects that are far away.
WHICH LENSES ARE USED?
Lenses
To correct myopia, lenses tend to be thicker at the edge. The more severe the myopia the thicker the edges of the lens, creating the unpleasant bull’s eye effect.
In addition, the more severe the myopia the heavier the lens, meaning glasses that are less comfortable.
NAU! SOLUTIONS
To correct myopia, we recommend a wide range of lenses that guarantee a good result aesthetically and with regards to performance : reduction of lens thickness, weight, and bull’s eye effect.
With this in mind we recommend lenses produced with particularly thin and lightweight materials that are designed using the most advanced technology. The lenses necessary for myopia correction can also be produced for sunwear to provide better vision comfort in the sun and to offer you the opportunity to enjoy wearing prescription sunglasses inspired by the latest fashion trends or in the desired colour.
Myopia

The NAU! Expert recommends: in the presence of medium, medium-high and high myopia small frames are better, because the smaller the frame, the smaller, lighter and thinner the lenses are.
Hyperopia

HyperopiaHyperopia

WHAT IS IT?
Difficulty in near vision and, to a lesser extent, also in far vision.
WHICH LENSES ARE USED?
Lenses
Lenses used to correct this condition tend to be thicker in the centre. The more severe the hyperopia, the thicker the lens in the centre, creating the unpleasant magnification effect.
In addition, the more severe the hyperopia the heavier the lens, meaning glasses that are less comfortable and stylish.
NAU! SOLUTIONS
To correct hyperopia we recommend lenses that can guarantee a good aesthetic and functional result: reducing the lens thickness weight and magnification effect.
With this in mind we recommend lenses produced with particularly thin and lightweight materials that are designed using the most advanced technology. The lenses necessary for hyperopia correction can also be produced for sunwear to provide better vision comfort in the sun and to offer you the opportunity to enjoy wearing prescription sunglasses inspired by the latest fashion trends or in the desired colour.

The NAU! Expert recommends: in the presence of hyperopia we recommend that you use aspheric lenses. This lens construction geometry guarantees better vision quality and reduced weight, thickness and magnification effect.
Astigmatism

WHAT IS IT?
Difficulty in seeing the image contours clearly.
WHICH LENSES ARE USED?
The lenses necessary for astigmatism correction are the same as those used for myopia or hyperopia but have a second correction parameter, called cylinder.

To correct astigmatism we recommend lenses that can guarantee a good aesthetic and functional result: reducing the lens thickness weight and magnification effect.
With this in mind we recommend lenses produced with particularly thin and light materials that are designed to the most advanced technology.

Presbyopia

PresbyopiaPresbiopia

WHAT IS IT?
Difficulty in seeing at reading distance.
WHICH LENSES ARE USED?
Lenses
Presbyopia can be corrected by using progressive lenses: lenses that enable you to see clearly at all distances using just one pair of glasses. Progressives are in fact lenses with three visual areas: near, intermediate and far.
The use of progressive lenses requires a short adjustment period, by the end of which visual ability becomes similar to natural vision.
NAU! SOLUTIONS
To correct presbyopia we recommend that you use progressive lens glasses that guarantee the following advantages:

• clear vision at all distances, from near to the infinite using just one pair of glasses
• no lines on lens, just like a normal prescription lens
• dynamic vision, close to natural vision.

Our stores offer a wide range of progressives that guarantee a good aesthetic and functional result.
In addition, depending on your visual requirements and lifestyle, we offer a range of progressive lens designs to provide glasses tailored specifically to your eyes.
The lenses necessary for presbyopia correction can be used in sunwear to provide better vision comfort in the sun and to offer you the opportunity to enjoy wearing prescription sunglasses inspired by the latest fashion or in the desired colour.
Presbyopia

The NAU! Expert recommends: at the first signs of presbyopia, it is recommended to start using progressive lenses to maintain a natural and dynamic vision.
OPTIONAL
OPTIONAL BENEFITS
ANTI-REFLECTIVE TREATMENT
With anti-reflective treatment the lens surface is coated with totally invisible metal substances that can eliminate reflection and glare from the surface of the lens.
Anti-reflective lenses are coated with hardening, water-repellent and anti-static substances.
High vision clarity through the lens.
Improved lens transparency: eyes are seen in their natural state.
Simpler lens cleaning, thanks to the water-repellent and anti-static particulates that repel dust and dirt.
Maggiore resistenza ai graffi.
Better scratch resistance.
UV protection.
TINTING
The lens is tinted by deeping in special substances with coloured pigments.
TINTING
Sunwear lenses guarantee you with better vision comfort in the sun and give you the opportunity of wearing prescription sunglasses inspired by the latest fashion trends or in the desired colour.
To provide you with optimal UV protection we recommend that you ask for UV treatment too.
UV TREATMENT
UV treatment consists of applying a special clear varnish to the lens that blocks ultraviolet rays from lens to the eye. UV lens treatment is highly recommended in prescription sunwear.
100 per cent protection from UV rays particularly harmful to the eyesight.
PHOTOCHROMIC LENSES
These lenses darken automatically when exposed to UV rays and lighten in a few instants in an environment with lower ultraviolet light. The process takes place because the external surface of the lens is treated with a special clear varnish containing UV light-sensitive micro cells. When these particles are touched by UV rays, they activate and darken the lens. When UV rays decrease, the lens gradually lightens and becomes clear again.
Photochromic lenses protect from UV rays.
Convenience of wearing just one pair of glasses that adapts to the light conditions outside.
It is worth remembering that photochromic lenses do not replace sunglasses lenses.
POLARIZED LENSES
All surfaces that reflect sunlight (snow, water, asphalt roads) act like a mirror, increasing the intensity of glare. Polarized lenses are designed to eliminate this issue. These lenses can select the sun radiation so as to reduce the intensity of light reaching your eyes. In this way images are perceived more clearly.
Improved quality of vision and comfort.
Total eye protection against UV rays particularly harmful to your eyesight.
HARD COATING
Hard coating is a treatment whereby a special clear varnish is coated on the lens surface increasing scratch resistance when dried.
Improved scratch resistance.
