The American Optometric Association issues guidelines on how to safely view the solar eclipse that will occur on Monday August 21, 2017. Here are the four tips:
- Use approved solar eclipse viewers. The viewers must meet international standard ISO 12312-2 for safe viewing.
- Technique of the pros. Before looking at the sun cover your eyes with the eclipse viewers while standing still. Glance at the sun, turn away and then remove your filter. Do not remove the filter while looking at the sun.
- Totality awesome. Only within the path of totality-and once the moon completely blocks the sun-can eclipse viewers safely be removed to view totality. Once the sun begins reappearing, however, viewers must be replaced.
- Visit your doctor of optometry. If you should experience discomfort or vision problems following the eclipse visit your doctor of optometry for a comprehensive eye examination.
