Hurricane Irma made landfall in Florida over the weekend, causing widespread damage, leaving millions of people without power.

The storm which has been downgraded from a hurricane to a tropical storm now moves toward the northwest, likely to strike southern states on Monday, according to CNN.

Close to 5.2 million people are without power in Florida, with FEMA chief Brock Long saying some places wont have power for weeks, CNN reported.

Flooding filled the streets of Miami, Naples and parts of Tampa, according to CNN.

Officials still warn people to stay off the streets, even as the storm winds die down.

"Stay off the roads, stay off the streets, let us complete our assessment, clear the roads of water, power lines, trees and then you can get out there and determine what happened to your individual property or your neighborhood," Fort Lauderdale Mayor Jack Seiler told CNN.

So far, few images of the damage have popped up, as the storm takes its final breaths on Florida. ABC News shared drone footage that depicts the aftermath of Naples, which was better than expected, officials said.

Reporters shared videos on Twitter of the storm, as they stood out during the fierce winds and savage rain to report on the devastation.

The Miami Herald shared its front page, which captured the devastation from the storms surge of seawater.

Miami faced floods.

A Miami roof got ripped off because of the winds.

One Naples resident tried to captured footage and was almost hit by a tree.

Glass panels fell from the Panorama, which is the tallest building in Miami.

Storm chasers stood outside to measure the storms strength. As Volusia emergency management said, do not do this!

One meteorologist could barely stand his ground during the storm.

Two Americans spoke with CBS News about what it was like to be in St. Martin during the storm.

CNN also shared drone footage of Tortola and the British Virgin Islands after Hurricane Irma.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
