A 37-year-old woman recently went to her eye doctor complaining of itching and watering eyes. While taking a close look, the doctor saw this freaky sight staring back.
It may sound like something out of “Star Trek”: Doctors have implanted a device in patients that has restored some central vision after advanced eye disease left those individuals with only limited peripheral vision. This is the first time that artificial and natural vision has ever been integrated in humans, the U.K.-based research team said.
Scientists have used stem cells to cure blindness in rabbits—which could be incredible news for visually impaired people.
Vision problems may sometimes be the only symptom a person has of a serious cardiovascular condition, a new case report suggests.
Eat For Your Eyes
Don’t worry, I’m not going to tell you to add carrots to every meal. You can enjoy a range of foods that are good for your eyes if they’re rich in lutein and zeaxanthin, two antioxidants found in veggies like dark leafy greens (think spinach and kale), Brussels sprouts and corn. In one large-scale study, researchers discovered that women whose diets contained the highest amounts of these eye-healthy nutrients were 32 percent less likely to develop cataracts than those who ate the lowest.
The eye is an organ of extreme perfection. I have a strong interest in evolution, and eyes have developed stunning adaptations over time. This mayfly (above) is a male with what are called turban eyes—greatly enlarged eyes at the top of the head in the shape of a turban. The male uses his eyes to scout for the silhouette of a female in the dim light of dusk. He doesn’t even have a working mouth. If you live for only one day, as adult males usually do, you don’t need to eat. But you do need tremendous eyes to find a female before you die.
