Presbyopia usually occurs beginning at around age 40, when people experience blurred near vision when reading, sewing or working at the computer. Researchers are exploring ways to treat presbyopia and eliminate the need for reading glasses. One of these new techniques, called PEARL, shows promising results. PEARL (PrEsbyopic Allogenic Refractive Lenticule) is a procedure that places a small piece of tissue from one part of the cornea into another part. This inlay changes the shape of the cornea, improving near vision. With the PEARL procedure, the eye surgeon uses a laser to make a small cut in the cornea. A small disc of corneal tissue, called a lenticule, is removed through this cut. The lenticule is sculpted and reshaped with a laser, then placed into a small pocket made in the patient’s cornea. PEARL may offer safety advantages over artificial corneal inlays for presbyopia. Because the inlay is made of the patient’s own tissue, it is biologically compatible, making it less like

Every five second one person go to blind and one child every  one minute go to blind in the world. World wide 39.8 percent blind and adding 1 to 2 million people in every year.  80 % blindness are in avoidable blindness. Wake up all and rise up to the situvation . So many programes are conducted by the part of VISSION 2020 , VISSION 2020 shut it down with in 4 years so all eye health professionals push up our limitis.

Toric IOLs are specially shaped IOLsdesigned to offset the imbalance created by the irregular shape of the cornea. Once implanted and aligned inside the eye, they stay fixed in place thereby eliminating pre-existing astigmatism. Here are several manufacturers of Toric IOLs that are available to correct various amounts of astigmatism. Your doctor will select the Toric IOL that is best suited for your eye condition. Toric IOLs are considered “premium” IOLs which means there will be additional costs associated with these lenses.

Per day Eight to ten hours spends younger generation in front of cell phone, tablet, computer or televisionscreens. All that screen time is causing eye strain and other vision problems. searchers surveyed more than 7,000 people and found that screen time is steadilyincreasing for kids and adults. Over the past year, the number of people who admitted spending 10 hours per day on electronic devices rose 4 percent. Problems can happen in eyes :- 1. Headache 2. Defective blinking cause dryness 3. Blue light leads retinal changes 4. Near vission affected How to fix the problems ?

ARMD is a major cause of blindness among individuals with European ancestry and accounts for more than 50% of all blinding conditions. The Eye Disease Prevalence Research Group estimates that 1.2 million U.S. residents are living with neovascular ARMD and 970,000 have geographic atrophy; these numbers expected to rise 50% by the year 2024. There are three major purported risk factors for ARMD: age, positive family history and smoking. In fact, smoking is the only consistently proven risk factor for ARMD. As with other age-related diseases, the free radical theory of aging has been proposed as an underlying cause of ARMD. This theory proposes that oxidative stress occurs in the retina because levels of reactive oxidative intermediates (ROIs) increase to a level that exceeds the detoxifying capacity of antioxidants. The researchers evaluated the protective effects ofzincand/or a formulation that consisted of nutrients with antioxidant properties,including vitamin C,vitamin E and beta-

                                  Zika virus can cause GLAUCOMA in infants Exposure to the Zika virus during pregnancy causes birth defects of the central nervous system, including microcephaly. Brazilian and Yale School of Public Health researchers had reported early during the microcephaly epidemic that the virus also causes severe lesions in the retina, the posterior portion of the eye. However, until now, there has been no evidence that Zika causes glaucoma, a condition that can result in permanent damage to the optic nerve and blindness. for more details : please click the link   sciencedaily.com

Using the latest technologies and methods to restore vision in the blinds   The bionic eye devices to restore a sense of vision to people with   retinitis pigmentosa and age related maccular degeneration. The bionic eye consist of a spectacle with centralised camera, external processor and a implant with a microchip and stimulating electrodes surgically placed in the back of the eye ball. The bionic vision system consists of a camera, attached to a pair of glasses,which transmits high-frequency radio signals to a microchip implanted in the eye. Electrodes on the implanted chip convert these signals into electrical impulses to stimulate cells in the retina that connect to the optic nerve. These impulses are then passed down along the optic nerve to the vision processing center of the brain.                                                                                                                          Another ways and technology use to retina detached,a

    BLUE LIGHT CAUSE TO MACULAR DEGENERATION The light is a energy source, so its pass energy one to another.The main source of the blue light and uv light such as digital                   screens,TV,COMPUTERS,LAPTOPS,SMARTPHONES,TABLETS,FLUORESCENT LIGHTS,LED LIGHTS etc..... it was include the main energy source SUN.                                                                                                          Blue light has a wavelength of between approximately 380nm and 500nm; making it one of the shortest, highest-energy wavelengths.                              The majority studies are indicates,the 60  %   of  peoples are spent more than six hours in a day in the digital media.       Blue light  exposure was lead to macular degeneration and permanent loss of vision.
