On April 8, 2024, a total eclipse will cross parts of North America. The astronomical spectacle is what happens when the moon passes between the sun and Earth and completely blocks the sun, darkening the sky during daytime. , the eclipse will start in 맥스카지노�South Pacific Ocean and will cross North America, passing over Mexico, United States, and Canada.맥스카지노� Weather permitting, the phenonom will be visible in Texas before traveling through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine, before exiting continental North America at 5:16 p.m. NDT.

But as enticing as it is to stare into the sky waiting for the eclipse, looking directly at the sun is never a good idea unless it맥스카지노�s completely blocked by the moon 맥스카지노� . Otherwise, stick to eye proper protection in the form of solar eclipse glasses.

맥스카지노�Regular sunglasses are not OK to watch the eclipse with. We are protecting our sight with these simple tools,맥스카지노� says Kelly Korreck, Ph.D., NASA맥스카지노�s eclipse program manager in Washington, D.C.

Luckily, it isn맥스카지노�t too hard to tell which eclipse glasses are safe맥스카지노�the (ISO) 12312-2 certification has set clear guidelines for glasses that맥스카지노�ll keep your eyes protected. Korreck says, 맥스카지노�This is the beauty of a standard맥스카지노�the glasses that meet this standard all should work about the same and protect one of our most valuable tools맥스카지노�our sight.맥스카지노�

If you don맥스카지노�t want to make your 맥스카지노�or use one of Korreck맥스카지노�s recommended 맥스카지노�we found a slew of solar viewing glasses that are certified for safety so you can look at the eclipse as it happens. These protect your retinas from permanent eye damage or even vision loss while providing a glimpse at annular eclipses and this year맥스카지노�s total eclipse, right before the phenomenon hits totality.

From bargain buys to sun spotting binoculars, these are the best solar viewing glasses and products to protect your eyes from the sun맥스카지노�s harmful rays.

What to Consider

Safety

Solar viewing glasses, also called eclipse glasses, have specialized lenses that block harmful radiation from penetrating your eyes and protect them from vision issues or even blindness. It doesn맥스카지노�t matter how dark or thick those glasses are; regular sunglasses are unsafe to use to look at the sun.

According to Richard Tresch Fienberg, PhD and Project Manager of the AAS Solar Eclipse Task Force at the , 맥스카지노�such filters are at least 1,000 times darker than the darkest ordinary sunglasses. They not only dim the sun맥스카지노�s visible light by a factor of 100,000 to several million, but also block potentially harmful ultraviolet and infrared radiation.맥스카지노�

The safest solar viewing glasses carry the ISO compliance label on their packaging. Look for any solar viewing glasses marked as being in line with the ISO 12312-2 (sometimes labeled as ISO 12312-2:2015) international safety standard. Although ISO sets the standards, a third-party lab tests products against the standard맥스카지노�the ISO does not approve or certify products itself. ISO-compliant sunglasses reduce sunlight to safe viewing levels and block solar UV and IR radiation.

Although the ISO is independent, both and the recommend using its approved products. Alternatively, NASA says 맥스카지노�considered the highest caliber of eye protection for welders맥스카지노�can also be used for viewing the sun.

맥스카지노�At no time during an annular or partial solar eclipse is the entire disk of the sun covered,맥스카지노� says Fienberg, 맥스카지노�and even the tiniest sliver of the sun맥스카지노�s brilliant face cannot safely be viewed directly. Looking at the sun without eye protection risks injury to the retina, the light-sensitive surface lining the inside back of the eye. Our instinct to turn away from intense light protects us from retinal injury.맥스카지노�

Even when you맥스카지노�re wearing eclipse glasses, don맥스카지노�t look through a camera lens, binoculars, or telescope as it맥스카지노�ll amplify solar rays and cause them to burn through the retina.

맥스카지노�Extremely bright light causes photochemical reactions in the retina맥스카지노�s rod and cone cells, damaging them so that they no longer respond properly,맥스카지노� Fienberg says. 맥스카지노�If the exposure is brief, the injury will heal over time. But if the exposure is too long, the damage will be permanent, leaving you with blind spots.맥스카지노�

If your lenses are scratched or torn, throw them away맥스카지노�you need complete protection to keep those eyes from UV and IR harm. And make sure to wear your glasses before and after the event to reduce the risk of injury.

Style and Budget

Fienberg says that the most common and least expensive eclipse glasses have cardboard frames with lenses made from a thin, metal-coated polyethylene film or a thin black-polymer resin, sometimes with a metal coating on one side.

Plastic frames with thicker, more durable lenses are slightly more expensive, while 3-by-5-inch handheld viewers made with the same materials as cardboard eclipse glasses are available as well.

Legitimacy

Ebay, Amazon, and other major retailers often see an uptick in counterfeit solar viewing glasses from third-party sellers in the days leading up to an eclipse. A list of reputable manufacturers can be found at the website. These have been tested by the and are guaranteed to protect your retinas from temporary or permanent damage.

While NASA recommends only using ISO-approved eclipse glasses, it doesn맥스카지노�t officially endorse any pair. Products labeled 맥스카지노�NASA-approved맥스카지노� or similar rely on marketing tactics to sell safety. Avoid them.

As for trusted brands, Fienberg only recommends U.S. companies 맥스카지노�that have been around for decades and are likely to be around long after the 2023 and 2024 solar eclipses are behind us,맥스카지노� specifically calling out products by American Paper Optics and Rainbow Symphony. 맥스카지노�They both use metal-coated black polymer film manufactured by Thousand Oaks Optical, and most of the resellers on get their glasses from either APO or RS맥스카지노�including some big retail chains such as Home Depot, Lowes, and Walmart.맥스카지노�

Eclipse Glasses With Prescriptions

If you wear prescription eyeglasses or contacts, you may be worried about comfort during your eclipse spotting. Denise Hill, heliophysics communications and outreach lead at NASA, has good news for you: solar viewing glasses are constructed to work with existing frames. 맥스카지노�Eclipse glasses are meant to be worn over prescription glasses or contacts,맥스카지노� Hill says. 맥스카지노�They are not for 맥스카지노�viewing,맥스카지노� but rather, they act as a shield.맥스카지노�

For those with eyeglasses, consider grabbing a larger pair of eclipse glasses or even solar binoculars to assist.

How We Evaluated

To find the best solar eclipse glasses, we followed advice from authorities in astronomy and well guidance from NASA's and Senior Advisor to the Executive Officer and Project Manager for the American Astronomical Society Richard Tresch Fienberg, PhD. Our list consists of glasses from reputable manufacturers according to the , and two alternatives to traditional solar viewing glasses: binoculars for strong magnification and a pair of welder맥스카지노�s glasses for a sturdier build.
