Assessing occupational risks is the first step in drawing up company health and safety policy, and it is the duty of the employer to assess and provide the necessary PPE for employees to carry out their job safely.
It is important to clearly identify the types of risks present to provide each employee with suitable equipment and to check that the risks, directives, standards and markings on the protection are all in line with each other.
And this includes eye protection.
To help you with this task, the optics department at Bolle Safety has selected the best technology: lens materials, design quality, coatings and tints, to protect and optimise your employees’ eyesight.
Let’s take a closer look at the Bolle Safety lens material.
The main feature of polycarbonate is its resistance to impact. This material is by far the most resistant of all and it is particularly recommended for protection in the workplace.
Polycarbonate is 10% thinner than glass and 15% thinner than CR39. But it is a soft plastic and is therefore easily scratched. An anti-scratch coating is applied as standard to remedy this issue.
Polycarbonate has the added advantage of absorbing all ultraviolet rays from 280 nm up to 380 nm (99.99%).
Lens markings = 1FCE
European standards EN166 - EN170 - EN172
Rating: 1.59
This is an organic resin lens, which is stronger than glass lens, 50% lighter and absorbs part of ultra-violet rays.
On the other hand, they scratch more easily, so a hard coating is applied to the lens. At equal power, they are thicker than glass or polycarbonate lenses.

Trivex® glass initially has the advantages of polycarbonate and CR39. Indeed, Trivex® is more robust than CR39 and, unlike polycarbonate, is highly resistant to chemicals and solvents.
It is also one of the lightest materials on the market thanks to a density of 1.11g/cm3 which ensures perfect optical vision and filters out 100% of UVA and UVB rays.
Trivex® is however more expensive than other materials and has a narrower correction range than CR39 or Polycarbonate.
