For visible light, the user should only be able to see the Sun, sunglint reflected off shiny metal, halogen bulbs, the filament in unfrosted incandescent bulbs, and similarly intense sources. Determining whether the glasses effectively block enough UV and infrared light requires the use of , which is a rather expensive piece of lab equipment. The eye's retina lacks , and thus damage can occur without one's awareness. The AAS said products meeting the ISO 12312-2 standard avoid risk to one's eyes, and issued a list of reputable vendors of eclipse glasses. The organization warned against products claiming ISO certification or even citing the same number, but not tested by an accredited laboratory. Another problem was counterfeits of reputable vendors' products, some even claiming the company's name such as with American Paper Optics which published information detailing the differences between its glasses and counterfeits. Andrew Lund, the owner of a company which produces eclipse glasses, noted that not all counterfeit glasses were necessarily unsafe. On July 27, 2017, Amazon required all eclipse viewing products sold on its website have a submission of origin and safety information, and proof of an accredited ISO certification. Short-term damage includes solar keratitis, which is similar to sunburn of the cornea. Symptoms usually occur within twenty-four hours and include eye pain and light sensitivity.

Depending on the severity of damage, vision problems can last for several months or be permanent. Lensrentals, a camera rental company based in , reported that many of its customers returned cameras and lenses with extensive damage. The most common problem reported was damage to the camera's. This most often happens when shooting in mode, where the sensor is continuously exposed to the eclipse image and becomes damaged by the sun's light. Another problem was the heat and brightness of the eclipse destroying the lens iris, which mechanically regulates the amount of light that enters the camera. The cost of all of this damage likely amounted to thousands of dollars. A on , alerting drivers of the eclipse Officials inside and near the path of totality planned — sometimes for years — for the sudden influx of people.

Idaho's Office of Emergency Management said Idaho was a prime viewing state, and advised jurisdictions to prepare for service load increases; nearly every hotel and motel room, campground, and in some cases backyards for nearly 100 miles 160 km north and south of the path of totality had been reserved several months, if not years, in advance. The state anticipated up to 500,000 visitors to join its 1. Oregon deployed six aircraft and 150 soldiers because the influx of visitors coincided with the state's fire season.

In Oregon, because an estimated one million people were expected to arrive, the Oregon National Guard was called in to help manage traffic in along and. Officials in Idaho, where the totality path crossed the center of the state, began planning for the eclipse a year in advance. The suspended construction projects along , which traverses , from August 18—22 in order to have all lanes open; , where many were expected to travel the 220 miles 350 km north via the highway from the , did the same. The ISP stationed a patrol car along I-15 every 15 miles 24 km between and the Utah border. The ISP tweeted a picture of bumper-to-bumper traffic stalled on the interstate just south of. Motorists reported to local news outlets that it was taking them two hours to travel the 47 miles 76 km from that city to to the south, a journey that normally takes 45 minutes. Others reported that it took three hours to travel from Idaho Falls to the closer city of , 30 miles 48 km farther north of Pocatello. In the rest of the state the impact was less severe. Traffic nearly doubled on , and was up 55 percent on. For some northbound travelers on , the had failed to make similar plans to those in Idaho, scheduling a road construction project to begin on August 21 that narrowed a section of the highway to a single northbound lane, near the exit to south of. Though that stretch of highway generally has a traffic count of less than 1,000 vehicles per day, on the day of the eclipse there were over a thousand vehicles per hour at peak times. As a result, traffic backed up as far as , creating a delay of at least an hour for travelers heading northward.

A spokesman for the allowed that the traffic jams were the worst he had seen in six and a half years on the job, noting that accidents had aggravated the already heavy traffic flows, attributed the I-75 congestion to -area residents heading for the totality path at and returning during what was the city's normal afternoon rush hour. Before the eclipse, state officials had described their traffic expectations as equivalent to that generated by the , the twice-a-season races at or the formerly-held fireworks festival. Alert signs on the highways also warned motorists not to pull over onto the shoulders to watch the eclipse as it could increase the risk of dangerous accidents and block the path of emergency vehicles.

The en masse departure of tourists via Interstate 69 as well as the Western Kentucky Parkway resulted in commute times double or even triple of normal. The Hopkinsville-to-Lexington commute under normal circumstances lasts three and a half hours. An eclipse causes a reduction of generation where the Moon shadow covers any solar panel, as do clouds. The predicted minor impacts, and attempted to measure the impact of the 2017 eclipse. Around 4 GW mainly in North Carolina and Georgia were expected to be 90 percent obscured. After the 2017 eclipse, grid operators in California reported having lost 3,000—3,500 megawatts of utility-scale solar power, which was made up for by hydropower and gas reliably and as expected, mimicking the usual. When the eclipse began covering California with partial darkness, which reduced its usual amount of solar-generated electricity, NV Energy sent power there. Likewise, when Nevada received less sunlight, other west coast states supplied electricity to it. During the solar eclipse, the state of Nevada lost about 450 megawatts of electricity, the amount used by about a quarter million typical residences. The caused manageable solar power decreases in Europe; in Germany, solar power dropped from 14 to 7 GW, of a 38 GW solar power capacity. A took place on August 7, 2017, in the same. It was visible over Africa, Asia, Australia, and eastern Europe.
