As reported by Eye7 Chaudhary Eye Centre when your retina gets damaged your vision gets seriously impaired. Main causes for damage to the retina are diabetes, hypertension but also old age, if you are having an eye problem visit an eye clinic. A technological solution to that problem might be the “Bionic Eye”.
Light amplification could be achieved by implanting quantum dots – nanoscale specks of semiconductor – into the retina. These fluoresce when hit by photons and would have the effect of making any received retinal image brighter.
Taking care of Contact Lenses is critical to protect your sight. Yesterday I switched back to contact lenses from glasses. I have worn contacts off and on for the last 25 years or so and over the last three years I have almost exclusively worn contact lenses. I rememver the last time that I got contact lenses my optometrists asked me how long I wore my contact lenses and I replied “about 12 hours a day”, he was shocked and asked me what I had against my eyes to treat them so badly.
Quantum dots have several advantages: they require no external power source, are much smaller than silicon chips, and can be coated with a bioactive material that causes them to become lodged in only specific tissues in the retina.
Tests on rats have shown this approach works, the patent application says. Rats that had quantum dots injected into their retinas afterwards had more electrical activity in their retinas than those that received control injections of saline, or no treatment at all.
University of Colorado Hospital’s Jeffrey Olson has developed a procedure for improving eyesight that involves injecting nano-sized semiconductors called “quantum dots” into the retina. Most of the people who suffer from vision problem are asymmetric pupillary distance,
Pupillary distance (or PD) is the distance between your pupils and it’s measured in millimeters (mm). Remember, your pupils are the dark circles located within the colored iris of your eye. The aim of PD is to line up the center of your lenses with the exact center of your eyes. Makes sense, right? Without a good pupillary distance measurement, your prescription glasses might do more harm than good. You could experience blurriness, headaches, double vision, nausea, or other eyesight issues if the measurement is off.
Make sure to request that your doctor includes your pupillary distance (PD) with the prescription. Having your pupillary distance (and the exact measurement in millimeters!) allows our team to locate the optical center of your lenses so that your prescription is correctly placed. With this pupil detection and location we’re able to offer you the best prescription glasses solution.
The number of people suffering seriously impaired vision due to damaged retinas is increasing in the developed world, as populations age and diabetes becomes more common, however this one can be treated with Child & Family Eyecare. The search for a technological solution to the problem has led to growing interest
