Acanthamoeba keratitis is a rare but serious eye infection primarily affecting contact lens wearers, caused by a parasite found in water and soil, which can lead to permanent vision loss if not diagnosed and treated early. Proper lens hygiene, avoiding water contact, and prompt medical attention are crucial for prevention and management.
Novelty contact lenses can enhance Halloween costumes but pose serious risks like infections and eye damage if not purchased and used safely. It's recommended to buy from reputable sources, preferably with a prescription, and to follow proper hygiene practices to avoid eye injuries or vision problems.
Eye doctors recommend avoiding sleeping in contact lenses, ignoring eye exams, staring at screens without breaks, ignoring sudden vision changes, leaving makeup on overnight, looking directly at the sun, smoking or vaping, rinsing contacts with tap water, eating an unbalanced diet, and neglecting eye lubrication to maintain healthy eyes and prevent serious issues as we age.
Eye doctors advise against sleeping in contact lenses, ignoring sudden vision changes, staring at the sun, smoking, and neglecting regular eye exams. They emphasize the importance of proper contact lens hygiene, protecting eyes from UV damage, maintaining a balanced diet, and seeking prompt medical attention for eye issues to prevent serious damage and preserve vision.
Justin Herbert is wearing UV protection contact lenses to improve his vision and reduce squinting during games, opting for tinted lenses over visors, and plans to confirm their league compliance for the season.
Researchers at the University of Science and Technology of China have developed contact lenses containing upconversion nanoparticles that enable humans to see infrared light without external power, potentially revolutionizing vision and applications in security, medicine, and beyond.
Scientists have developed contact lenses embedded with nanoparticles that enable humans to see in total darkness and detect infrared signals, potentially transforming fields like medicine and firefighting by allowing users to see through smoke or locate tumors without additional equipment.
Scientists have developed contact lenses that enable users to see in the dark by converting infrared light into visible light, with potential applications including aiding colorblind individuals and transmitting wireless data, though the technology is still in development and not yet perfect.
Brooklyn McCasland, a 23-year-old from Texas, lost vision in her right eye after contracting Acanthamoeba keratitis, a rare parasitic eye infection, from swimming with contact lenses. Despite practicing good lens hygiene, she was unaware of the risks of wearing contacts in water. The infection, which is difficult to diagnose, has left her in severe pain and light sensitivity, requiring a corneal transplant. McCasland aims to raise awareness about the dangers of mixing contact lenses with water.
Top eye surgeons are warning of a growing risk of blindness in children due to excessive screen time and lack of outdoor activities, leading to a surge in cases of myopia. Children as young as four are now wearing special contact lenses to counter the problem, with some experiencing severe short-sightedness. The prolonged use of screens and reduced time spent outdoors during the Covid pandemic have exacerbated the issue, prompting calls for parents to limit screen time and ensure children get ample daylight exposure.
The CDC has linked Acanthamoeba infections to nasal rinsing, particularly through the use of neti pots, and poor hygiene in people who use contact lenses. Acanthamoeba is a dangerous amoeba found in the environment that can cause rare but severe illness and death. Symptoms of infection can include eye discomfort, skin infections, and serious neurological problems. The CDC recommends using boiled, sterile, or distilled water for nasal rinsing and following strict hygiene practices for contact lens use to prevent infection.
Ophthalmologists have developed a spiral-shaped contact lens, known as the spiral diopter, that maintains clear focus at different distances and in varying light conditions, potentially revolutionizing ophthalmology. The lens, inspired by severe corneal deformations, creates an optical vortex that allows for multiple clear focus points, simplifying the process of creating optical vortices and marking a significant advancement in optics. The lens could benefit contact lens technologies, cataract implants, and compact imaging systems, offering a powerful tool for depth perception in advanced imaging applications.
Scientists have developed a revolutionary spiral-shaped contact lens that utilizes an "optical vortex" to enable the eye to focus at different distances and in various lighting conditions. The lens, known as a spiral diopter, could potentially transform ophthalmology and also find applications in miniaturized imaging systems. Unlike existing multifocal lenses, the spiral diopter maintains multifocality regardless of pupil size and lighting conditions, offering consistently clear vision. While further research and testing are needed, the lens has shown promising results in simulations and volunteer experiments, with potential applications in eyewear and compact imaging systems.
During a broadcast of Today with Hoda and Jenna, NBC anchor Hoda Kotb experienced an on-camera incident involving a contact lens getting stuck in her eye, prompting concern from co-host Jenna Bush Hager. Contact lens wearers can relate to the discomfort caused by such incidents, and advice was given on how to handle the situation. Ultimately, it serves as a reminder to always remove contact lenses before bed.
A 25-year-old woman in the UK almost lost her vision after developing an ulcer on her eye caused by her contact lenses. Initially experiencing itchiness, she consulted an eye doctor who discovered aggressive bacteria in her eye, leading to the ulcer on her cornea. Despite daily antibiotics, the ulcer did not heal, resulting in a cornea transplant. Her vision has improved, and it is hoped it will fully return by October. The incident highlights the importance of regular sight tests and immediate consultation with an optometrist for any eye concerns.
