Solar eclipse: Avoid eye damage with these precautions

Published

 on

If you are eagerly awaiting the total solar eclipse on April 8, there are some precautions you will want to take to protect your eyesight.

Dr. Mark Eltis, a Toronto-based optometrist, told Global News that viewers of the eclipse will need special glasses, with ISO 12312-2 rating, to protect their eyes from any possible damage.

“Those glasses are much darker than regular sunglasses,” he said. “You can’t wear regular sunglasses.”

The eclipse can provide a false sense of safety since the sun will be dimmer, but harmful rays are still present, he added.

Without proper eye protection, the light rays that do shine through will travel to the back of the eye, called the retina. That’s where the cells interpret the light and send the information to the brain. Damage from those rays can happen within a minute, Eltis said, and you won’t even feel it is happening.

“Our pupils will be more dilated because there’s less light, so the rays will go to the back of the eye and they can burn those cells that interpret the light,” Eltis said. “That’s the danger.”

You will only know there is damage “when it’s too late,” according to Eltis, and while the damage can be temporary, it can also be permanent.

Dr. Avnish Deobhakta, an ophthalmologist based in New York State, told Global News a story of a patient in New York City who was walking down the street during the 2017 solar eclipse. She looked up at the spectacle for about six seconds, realized she needed eye protection, borrowed glasses she thought were protective, and then looked at the eclipse for another 30-40 seconds.

“Unfortunately, about four hours later, she noticed that she had a defect in her vision,” Deobhakta said.

He said that they found damage in her retina in the shape of the eclipse. The sliver of the sun exposed during the eclipse had burned itself into her retina.

“The problem in New York City was that it was a partial eclipse.”

Deobhakta said that the rays of sunlight that make it past the moon during a partial eclipse, like that which will happen in Toronto on April 8, are usually the more powerful ones.

If you are watching a total solar eclipse, as will occur in certain parts of Canada, Eltis said it is possible to look at it without special glasses when it is in totality, but said it is dangerous if you are not sure when exactly that is happening.

The eclipse will pass through Ontario, Quebec, New Brunswick, Prince Edward Island, Nova Scotia, and Newfoundland and Labrador. Several cities and towns will go into complete darkness for a few minutes during the day.

The last time a total solar eclipse passed through Canada was in 1979.

A total solar eclipse occurs when the moon passes between the sun and the Earth, aligning perfectly and completely blocking the sunlight.

The eclipse will occur between mid and late afternoon in Canada, depending on location.

Even if you wear the protective glasses, Eltis suggests you look down at the ground before looking up at the sun, and then look down again after viewing the eclipse.

Deobhakta also recommended creating a projection device that you can wear to avoid any damage, as described on the Government of Canada website.

Symptoms of eye damage include blurry vision as well as black spots. If you feel something has changed in your vision, see an eye doctor, Eltis said.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
