3:17 Geneva introduces driverless buses – 15 self-driving minibuses will be deployed in 2025. Providing an on-demand, door-to-door service, 24 hours a day. This pilot project will run for 1 year alongside similar schemes in Germany and Norway.

4:55 Implants restore vision to blind people – The implants were given to 20 people by scientists at Sweden’s Linköping University and LinkoCare Life Sciences. 14 were blind and 6 were on the verge of losing their sight. After 2 years, none of them were blind.

Eye Health: The Causes Of Nearsightedness (Myopia)

Cleveland Clinic – Nearly 1 out of 3 people have a vision disorder called myopia, or nearsightedness, which makes it difficult to view things in the distance. How does it happen? And is there a cure?

Chapters: 0:00 Intro 0:32 What causes nearsightedness? 1:01 Why can’t you see far? 1:20 When does nearsightedness usually begin? 1:42 What are symptoms of nearsightedness? 1:59 Can nearsightedness be corrected? 2:23 Is there a cure for nearsightedness?

What is myopia?

People who have myopia (also known as nearsightedness) have difficulty seeing distant objects, but can see objects that are near clearly. For example, a person who is nearsighted may not be able to make out highway signs until they are just a few feet away.

Myopia affects a significant percentage of the population. It’s an eye focus disorder that is easily corrected with eyeglasses, contact lenses or surgery.

How common is myopia?

Myopia is very common. According to the American Optometric Association, more than 40% of Americans are myopic, a number that is rapidly rising, especially among school-aged children. Eye experts expect this trend to continue in the coming decades.

Today one in four parents has a child with some degree of nearsightedness. Some eye experts believe that if your child spends an extraordinary amount of time engaged in “near” activities, such as reading or using smartphones and computers, it may raise the risk of developing myopia.

Can myopia lead to blindness?

Usually, myopia is a minor nuisance that can be corrected with eyeglasses, contact lenses or surgery. But in rare cases, a progressive type called degenerative myopia develops that can be very serious and is a leading cause of legal blindness. Degenerative myopia affects only about 2% of the population. It is believed to be inherited and is more common in Jewish, Japanese, Chinese and Middle Eastern people.

Views: The Beautiful And Bizarre ‘Eyes” Of Animals

“The cornea, which in fish is simply a transparent protective cover for the eye, became an image-forming structure in its own right,” wrote the late Michael Land, a biologist at the University of Sussex in England, in a 2005 study in the journal Current Biology, “because it now had air on one side and water on the other.”

Some organisms have kept basic structures—flatworms and mollusks still have their simple pit eyes—while others sprouted mirrored components, elaborate pupil dynamics and arrangements that let their owner see above and below a waterline simultaneously. Even in animals that rely primarily on sensations besides sight, incredible eye features persist.

Health Talk: “Macular Degeneration” – Diagnosis & Treatment (Mayo Clinic)

On the Mayo Clinic Radio podcast, Dr. Sophie Bakri, a Mayo Clinic ophthalmologist and retina specialist, discusses macular degeneration, a common eye disorder with age. This interview originally aired Feb. 29, 2020.

Dry macular degeneration is a common eye disorder among people over 50. It causes blurred or reduced central vision, due to thinning of the macula (MAK-u-luh). The macula is the part of the retina responsible for clear vision in your direct line of sight.

Dry macular degeneration may first develop in one eye and then affect both. Over time your vision may worsen and affect your ability to do things such as read, drive and recognize faces. But this doesn’t mean you’ll lose all of your sight.

Early detection and self-care measures may delay vision loss due to dry macular degeneration.

Diet Studies: Age-Related Macular Degeneration Linked To Processed, Refined And Fried Foods

From a Genetic Engineering & Biotechnology News release:

Age-Related Macular Degeneration“Our work provides additional evidence that that diet matters,” Millen added. “From a public health standpoint, we can tell people that if you have early AMD, it is likely in your best interest to limit your intake of processed meat, fried food, refined grains, and high-fat dairy to preserve your vision over time.”

Participants who ate a diet high in red and processed meat, fried food, refined grains, and high-fat dairy were three times more likely to develop an eye condition that damages the retina and affects a person’s central vision, according to the results of a study, “Diet patterns and the incidence of age-related macular degeneration in the Atherosclerosis Risk in Communities (ARIC) study,” from the University at Buffalo (UB) that appears in the British Journal of Ophthalmology.

The condition is called late-stage age-related macular degeneration (AMD), which is irreversible and affects a person’s central vision, taking away their ability to drive, among other common daily activities.
