About TÜV Rheinland Eye Comfort 3.0
TÜV Rheinland Eye Comfort 3.0 certification
program presents a consumer-friendly star rating
scheme to the display industry promoting eye
wellness from safety to eye care. Compared to
existing certifications, the 5-star-rating program
adds rigorous testing requirements on overall
eye care attributes such as low blue-light, flicker-
free, refresh rate, color gamut, color accuracy
and ambient light sensor performance. It lays
out requirement metrics and rates the product
performance on five levels, and the sophisticated
technical assessment process provides consumers
and buyers with indicators that are easier to judge.
The eye wellness factors being considered remain
constant, however, the standards for the various
star ratings are different. The higher the star
rating, the more stringent the standards. The table
below lists the major eye comfort requirements
which apply in addition to the basic eye comfort
requirements (such as pixel density, uniformity of
luminance and color, and freedom of movement).
