Early eye disease test developed
A new, quick and simple eye test can predict who is more at risk of age-related macular degeneration (AMD), a leading cause of blindness worldwide. Researchers at Australia’s Vision Centre (VC) have found that while people with early AMD can still see in fine detail, other parts of their vision may be damaged and this […]

If you’re one of the 36 million contact lens wearers in the U.S., chances are you went through a mini-course in hygiene when you first got your prescription. You know the drill: First wash your hands with soap and water before drying them with a clean, lint-free cloth or paper towel. Then, carefully take the contact lens […]
Read More...Automated Method to Detect Glaucoma in Its Early Stages
A team of researchers led by Jun Cheng of the A*STAR Institute for Infocomm Research, Singapore, has developed a novel automated technology that screens for glaucoma more accurately and quickly than existing methods1. Glaucoma is a chronic, progressive eye disease that damages the optic nerve. It is the second leading cause of blindness worldwide, and […]

In some cases of corneal disease, a scleral lens fitting is the only option that can save a patient from undergoing a corneal transplant. This article describes just such a patient from Sao Paulo, Brazil, who came to our clinic at Instituto de Olhos Dr. Saul Bastos (IOSB) in southern Brazil. He had bilateral keratoconus, […]

People with cataract-related vision loss who have had cataract surgery to improve their sight are living longer than those with visual impairment who chose not to have the procedure, according to an Australian cohort study published this month in Ophthalmology, the journal of the American Academy of Ophthalmology. After comparing the two groups, the researchers found a […]

Drawing heavily upon nature for inspiration, a team of researchers has created a new artificial lens that is nearly identical to the natural lens of the human eye. This innovative lens, which is made up of thousands of nanoscale polymer layers, may one day provide a more natural performance in implantable lenses to replace damaged […]
Read More...The Camera Versus the Human Eye
This article started after I followed an online discussion about whether a 35mm or a 50mm lens on a full frame camera gives the equivalent field of view to normal human vision. This particular discussion immediately delved into the optical physics of the eye as a camera and lens — an understandable comparison since the […]
Read More...New layer of the eye discovered
A new layer in the front layer of the human eye has been discovered by researchers at The University of Nottingham. The findings, published in the journalOphthalmology, could significantly help doctors carry out corneal grafts or transplants. The layer has been called the “Dua’s Layer”, named after the researcher who led the study, Professor Harminder […]
Read More...Basic Anatomy of the Eye
Although small in size, the eye is a very complex organ. The eye is approximately 1 inch (2.54 cm) wide, 1 inch deep and 0.9 inches (2.3 cm) tall. The tough, outermost layer of the eye is called the sclera. It maintains the shape of the eye. The front sixth of this layer is clear and […]

What allows you to read the articles in this magazine? Obviously, at a more complex level, you have to understand the English language. But before you even begin to decipher what is written, you must see it. In fact, an amazingly complex series of actions takes place between your eyes and your brain for you to see […]
