The Future of Eye Lens Radiation Protection – Model BR330

The common goal of setting new standards for radiation protection glasses
and eye lens dosemetry has united the three project partners Dosilab,
the AWST Evaluation Centre of the Helmholtz Centre and MAVIG.


  • Precise and reliable dose determination
  • Accredited measurement laboratory in Switzerland and in several European countries
  • More than 50 years of experience in dosemetry


  • Germany’s oldest and largest individual dosimetry laboratory
  • Largest measurement laboratory
    in Europe
  • Individual-, local- and environmental dosimetry at a high level
  • Accredited measurement laboratory with over 1.8 million evaluated dosemeters per year


  • Manufacturer of high-quality medical devices and personal protective equipment
  • Leader in quality and innovation in the field of X-ray protection since 1921
  • Innovative research and development with experience and craftsmanship


The pooling of our expertise in the fields of radiation protection, dosemetry,
and dosemetry services has resulted in a product that confidently meets
the  requirements of today and those of the future.

With the implementation of the European EURATOM Directive 2013/59
into national law on 6 February 2018 and the new Radiation Protection
Act (which came into force on 01/10/2017), the annual limit value for the eye lens dose will, for the first time be set at a mandatory threshold
limit of 20 mSv per year (for persons over 18 years of age).


Integration of Dosemeters

In the case of monitoring the eye lens dose, a constant position
of the dosemeter(s) is most ideal. Together with project partners
AWST Evaluation Centre of the Helmholtz Centre and Dosilab,
MAVIG has developed a new type of radiation protection glasses
that integrates lens dosemetry into the approach in a beneficial way.

The BR330 glasses allow the use of dosemeters due to the patented
dosemeter connection on the left, right or on both sides.
The dosemeter connection has been designed in such a way that
there are no user restrictions and yet the best possible dosemetry
is guaranteed.


Special Quality Features Optimise Use in the Medical Field

  • Frame made of high-quality plastic materials with high shape stability
  • Complete elimination of the use of plasticisers during production
  • The materials used ensure the glasses are as hypoallergenic as possible
  • Design and material help prevent the risk of injury
  • Easy cleaning and a high degree of chemical resistance (resistance to disinfectants)
  • Standard anti-reflective coating of the lenses
  • Optical corrections are available both as single-vision and varifocal/progressive lenses


  • Ocean Blue, universal/adjustable
  • Obsidian Grey-Black, universal/adjustable

Lead equivalent value at 50 – 150 kV, extended front / lateral protection (weight):

  • Pb 0.50 mm/ 0.50 mm (approx. 120 g)

Other Features:

  • Adjustable temple length
  • Inclination adjustable (± 22,5°)
  • Dosemeter mounting: none, left, right, or both sides
  • Anti-reflective coating of the lenses
  • Glasses strap
  • Conformity: IEC 61331-1:2014 / IEC 61331-3:2014
