Khi quan sát nhật thực không được quan sát trực tiếp bằng mắt thường.

Người xem nhật thực bắt buộc phải đeo kính chuyên dụng hoặc quan sát qua tấm phim lọc ánh sáng Mặt Trời để bảo vệ mắt.

Cơ quan Hàng không Vũ trụ Mỹ (NASA) ban hành một loạt hướng dẫn an toàn trước khi hơn 300 triệu người dân quan sát nhật thực toàn phần diễn ra vào tháng tới. Nhật thực sẽ bắt đầu vào ngày 21/8 ở bang Oregon và đi qua 12 bang trước khi kết thúc ở South Carolina. Bề rộng đường đi của nhật thực là 108km.
