It has been shown in various scientific studies that the wavelength’s spectre of the blue-ultraviolet light is harmful to the eye, being a factor that accelerates eye diseases such as cataracts, macular degeneration or retinitis pigmentosa.
Using these filters the person has fewer glares without losing visual acuity, improved contrast sensitivity, increased visual comfort, and even increased reading speed and therefore greater reading comprehension.[/vc_column_text][/vc_column][/vc_row][vc_row row_height_percent=”0″ override_padding=”yes” h_padding=”2″ top_padding=”0″ bottom_padding=”3″ overlay_alpha=”50″ equal_height=”yes” gutter_size=”4″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ el_class=”inverted-device-order” uncode_shortcode_id=”197672″][vc_column column_width_percent=”100″ gutter_size=”3″ overlay_alpha=”50″ shift_x=”0″ shift_y=”0″ shift_y_down=”0″ z_index=”0″ medium_width=”0″ mobile_width=”0″ width=”1/2″ uncode_shortcode_id=”353278″][vc_column_text uncode_shortcode_id=”110530″]Among these selective filters there are Corning selective filters, internationally recognized and which provide maximum protection from harmful lights.

The lighting environment in which they are to be used and the person’s degree of photosensitivity will determine the most suitable color for each person.[/vc_column_text][/vc_column][vc_column width=”1/2″][vc_single_image media=”101394″ media_width_percent=”100″ uncode_shortcode_id=”148509″][/vc_column][/vc_row]
