A new study from the Journal of the American Medical Association says that there are better options to make sunglasses cheaper than the competition.
Read moreAt least 10 years ago, researchers at the University of Arizona, who led the study, began investigating what made people wear sunglasses in the first place.
They found that they were made from a material that would help them blend in with the environment.
This material, called polyethylene, is made up of a series of layers of carbon nanotubes.
The layers combine to make the glass.
The researchers say that these layers were the main reason why sunglasses were designed with such low light-absorbing properties, and why they can be so easy to use.
“A high-quality, lightweight, low-cost, and high-performance eyewear is essential for people with disabilities,” said Dr. Jason Mazzocco, an associate professor of ophthalmology at the Mayo Clinic.
“When you’re looking at a person who is looking at an LED on a smartphone or computer screen, it’s very hard to make a good eye mask because the light from that LED is bouncing off of your retina,” he added.
“But with sunglasses, you don’t have to worry about that.”
Researchers found that the better the quality of the materials used to make glasses, the cheaper they would be to buy.
“This study is really about the consumer, and it’s about how sunglasses are made,” said professor Mazzucco.
“What are the benefits of this material?”
“We know that the materials that make up the lens of a light-emitting diode are very light-sensitive.
That’s why we’ve found that when you’re putting sunglasses on your face, the light is not bouncing off as much,” said co-author Dr. Scott Mott, an ophthalmologist at the Harvard School of Public Health.
“So, by putting materials that are really light-resistant on your eyes, you’re reducing the amount of light bouncing off the glass.”
The researchers found that polyethylenes are also less reflective than glass, which could mean that you could get the same results with a more expensive lens.
This means that if you have a high vision impairment, sunglasses might actually be cheaper than regular glasses.
The study is available online in the journal PLOS ONE.
