Focus Solar Eclipse Glasses with ND5 filter film (Focus Sport Optics, SKU: 116175) are intended for direct observation of the solar disc with the unaided eye. The ND5 filter material strongly reduces the intensity of visible light and blocks harmful ultraviolet and infrared radiation, enabling observation of the Sun during eclipses and on other occasions that require safe direct viewing of its disc.
The next total solar eclipse will occur on 2 August 2027 and will be one of the longest total solar eclipses of the 21st century. The path of totality will begin over the Atlantic Ocean, cross southern Spain and the Gibraltar region, and then continue through Morocco, Algeria, Tunisia, Libya, and Egypt. The Moon's shadow will then pass across the Red Sea, Saudi Arabia, Yemen, and Somalia before leaving land over the Indian Ocean. Near Luxor in Egypt, totality will last approximately 6 minutes and 23 seconds, providing an exceptionally long opportunity to observe the solar corona and the characteristic darkening of the daytime sky.
In Poland, the eclipse of 2 August 2027 will be visible as a partial solar eclipse. Depending on the observer's location, it will begin at approximately 10:16–10:27, reach maximum at approximately 11:17–11:22, and end at approximately 12:13–12:27 CEST. In Warsaw, the event will last from approximately 10:26 to 12:19, with maximum at 11:22 and a magnitude of 0.412. In Chorzów, it will last from approximately 10:20 to 12:21, with maximum at 11:20 and a magnitude of 0.483. Magnitude describes the fraction of the Sun's diameter covered by the Moon, so at both locations a clearly visible indentation in the solar disc will gradually grow and then recede. Because totality will not occur in Poland, protective glasses must be worn throughout the observation.
As demand tends to increase immediately before an eclipse, it is worth preparing the glasses well in advance, particularly when planning family, school, or group observations.

Warning! The glasses are intended exclusively for viewing the Sun with the unaided eye. Do not use them to look at the Sun through a telescope, binoculars, spotting scope, finderscope, camera, or any other optical device. Radiation concentrated by an optical instrument can damage the filter and cause permanent eye damage or loss of sight. When observing through optical instruments, use appropriate solar filters mounted in front of their objectives.
