Proteye Protects Your Eyes

Product information

Safety goggles

All Proteye safety glasses comply with the European directive 2016/425 for personal protective equipment EN166 and have been tested according to the legally required standards and guidelines by: Inspec International Ltd. Notified body: 0194

A brief description of the European eye protection standards EN 166
All manufacturers of safety glasses must comply with European standards. The frame and lenses are tested and must both bear the CE mark and the manufacturer's logo. The CE marking guarantees that the product meets the EU requirements of consumer safety, health and the environment.

EN 166 Personal eye protection
The frame is marked Proteye, EN 166 F and CE. This indicates that the frame has been tested and meets the European standard. Other information on the temples of frames; model number, spring length, color. Any additional information on the bridge of the nose; disc/glass size and nose size. The lenses fall into optical class 1. This is the highest optical class for everyday use.

The safety classes of glasses fall into the increased robustness class S, the minimum resistance is against the impact of a 22mm steel ball hitting the glass surface at 5.1 m/sec. The safety class with high speed with low energy falls into class F. The minimum requirement here is an impact resistance of a 6 mm steel ball with a speed of 45 m/s.

The markings you will find on the lenses are always: CE, Proteye logo and optical class 1. In addition, the lens resistance class markings; S, F.

Diving masks

To be able to make diving glasses for a diving mask, a number of basic data must be known. Depending on the type of glass that is desired, these include:

  • distance correction strength
  • correction strength nearby
  • pupil distance
  • pupil height
  • segment height

The segment height in particular sometimes gives rise to confusion. Proteye uses the so-called boxing system in which the height of the reading segment (H) is determined by measuring:

  • from the deepest point of the base pane in the mask (viewed from the outside) and above any visible silicone inner rim;
  • to the highest point of the reading part / segment transition to be made. Height=minimum 20mm

Reading parts
By default, the reading parts are round at the top. Bifocal lenses are also round at the dividing line between the distance and reading parts. Depending on the strengths, the dividing line is more or less visible, so it is important that it is not directly in front of the pupil.

It is recommended to indicate the height/segment transition with a (waterproof) marker, imitating the posture underwater as much as possible. This is often different from an upright position.

Draw a horizontal line that the customer looks over in the distance for vision and for possibly. reading looks underneath. This is the transition line between the reading and the verte part. So also for look-unders.

Pupillary distance
You can indicate/measure the pupil distance by having the customer look straight ahead and then place a mark at the height of the pupil. The distance between the two marks is the pupillary distance. You can do this. also measure with a ruler without a mask.
