Selected Dates in Vision:
Corrective Technologies and Innovations

ca.1286 — First glasses are created in Italy by the Dominican friar, Giordano da Pisa.

1508 – Leonardo da Vinci is first to introduce the concept of “contact lens” in his Codex of the eye, Manual D. Though none are produced at the time, the concept explored the idea of directly increasing corneal power of the eye.

1784 – Benjamin Franklin writes a letter to George Whatley, which describes his recent invention of “split double spectacles,” or bifocal lens glasses.

1786 – Valentin Haüy publishes a book titled An Essay on the Education of the Blind, in which he describes a process wherein the typographical characters used on a printing press would emboss letters upon the wet paper medium, thus creating a tactile font.

1823 – Creation of the first Fresnel lens, as attributed to Augustin-Jean Fresnel. Fresnel lenses are different from the regular spherical lens of a standard magnifying glass in that the former can be much thinner due to its structure, which is comprised of a set of thin raised concentric sections. As sight aids, Fresnel lens technology has been used to create flat magnification sheets that can be placed over a TV screen, helping to magnify the image.

1829 – Louis Braille publishes a book titled Method of Writing Words, Music and Plainsong by Means of Dots for Use by the Blind and Arranged for Them, exhibiting and explaining the original Braille type in French that is based on dots. More that half a century later, Braille type is introduced in Britain.

1837 – August Seebeck, classifies two distinct types of color blindness and is first suggest that the condition can be augmented with corrective lenses.

1851 – Hermann von Helmholtz invents the first ophthalmoscope, calling it an “eye mirror,” which is used to illuminate the interior of the eye behind the pupil.

1888 – Adolf Gaston Eugen Fick produces and fits the first successful pair of contact lenses. They are made of heavy blown glass with a dextrose solution inside. Although the original Fick lenses were a breakthrough, they were rather bulky and could only be worn for several hours at a time.

1905 – Eduard Zirm performs the first successful corneal graft surgery, by transplanting corneal tissue and partially restoring sight to a blind man named Alois Glogar.

1949 – Sir Harold Ridley performs the first-ever successful implantation of intraocular lens, a procedure that many contemporary ophthalmologists considered impossible at the time.

1980s – Scanning Laser Opthalmoscope is developed to view microscopic layers of the retina of the living eye, and aids in diagnosing retinal disorders.

1999 – Professor Ingo Potrykus invents Golden Rice. This genetically engineered varietal was designed to contain beta carotene, which, when consumed is converted to vitamin A in the human body. Since vitamin A deficiency is linked to blindness, especially in the developing countries, the Golden Rice, along with Orange-fleshed sweet potato, are examples of biofortification tools that aim to prevent vision problems linked to VAD in the future.

2001 – ChromaGen lens human subjects study is published in Ophthalmic and Physiological Optics. The study used the ChromaGen brand color blindness corrective lenses in a two-week experiment that yielded positive subjective results in its wearers, among which were the significant reduction of Ishihara error rates, the later being the most common color blind test of circles and dots of varying sizes and with numbers represented in contrasting colors.

2002 – Argus Retinal Prosthesis is developed by Second Sight TM. This bionic eye project created a product that is a retinal prosthetic system, which induces visual acuity of blind patients by means of electrical stimulation to the retina, bypassing the damaged photoreceptors. With an aid of compact camera and video processing unit (VPU), the device “sends” the scene captured via camera though a cable to the VPU, to reconstruct the visual information for the Argus-II wearer. In September 2012, FDA recommended the approval of the second-generation Argus-II device, following several successful clinical trials in Europe, Mexico and United States.

2005 – Elizabeth Goldring, artist, poet, and head of the Vision Group at the Center for Advanced Visual Studies at the Massachusetts Institute of Technology, leads a team of engineers and physicians in the development and first clinical trials of the Seeing Machine Camera (SMC). The device uses liquid crystal display (LCD) and light-emitting diode (LED) technologies to affordably and portably replicate principles of the industrial-grade Scanning Laser Opthalmoscope. The SMC projects imagery directly onto the retina with highly-focused, bright light, avoiding the normal distortions and refractions of the impaired eye. The SMC allows people with a visual acuity of 20/70 or less to see things they would otherwise be unable to see (including small details of facial features), and to produce photographs of what they see.

2009 – Gene therapy is shown to successfully cure color blindness in two squirrel monkeys. The therapy worked by increasing the red end of the spectrum sensitivity of cone cells, effectively restoring color vision in the study’s subjects. The results of the study suggest further implication for treating human color blindness in the future.

2010 – First success with biosynthetic cornea transplantation procedures is reported by Fagerholm et al. of Linkoping University in Sweden. The development of the biosynthetic corneas rose out of shortage of donated corneas readily available for transplantation. The corneas in the Fagerholm’s lab were produced by injecting the human gene, responsible for collagen production into a type of yeast cells that were later molded into the corneal shape.

2012 – Prosthetics + Mouse retina code

2013 – Implantable telescope for age-related macular degeneration


Living the American Dream, with or without eyesight

In anticipation of the forthcoming Glimpse issue on the theme of Blindness, we reflect on the societal contributions and civil rights of those born without, and those who have lost their eyesight, worldwide. Here in the United States, today, October 15, is Blind Americans Equality Day by resolution of the White House:  “Today, let us recommit to ensuring we remain a Nation where all our people, including those with disabilities, have every opportunity to achieve their dreams.” We couldn’t agree more. Read the Full White House resolution below.

The White House
Office of the Press Secretary
For Immediate Release
October 11, 2013
Presidential Proclamation — Blind Americans Equality Day, 2013

– – – – – – –

Blind and visually impaired persons have always played an important role in American life and culture, and today we recommit to our goals of full access and opportunity. Whether sprinting across finish lines, leading innovation in business and government, or creating powerful music and art, blind and visually impaired Americans imagine and pursue ideas and goals that move our country forward. As a Nation, it is our task to ensure they can always access the tools and support they need to turn those ideas and goals into realities.

My Administration is committed to advancing opportunity for people with disabilities through the Americans with Disabilities Act and other important avenues. In June of this year, the United States joined with over 150 countries in approving a landmark treaty that aims to expand access for visually impaired persons and other persons with print disabilities to information, culture, and education. By facilitating access to books and other printed material, the treaty holds the potential to open up worlds of knowledge. If the United States becomes a party to this treaty, we can reduce the book famine that confronts the blind community while maintaining the integrity of the international copyright framework.

The United States was also proud to join 141 other countries in signing the Convention on the Rights of Persons with Disabilities in 2009, and we are working toward its ratification. Americans with Disabilities, including those who are blind or visually impaired, should have the same opportunities to work, study, and travel in other countries as any other American, and the Convention can help us realize that goal.

To create a more level playing field and ensure students with disabilities have access to the general education curriculum, the Department of Education issued new guidance in June for the use of Braille as a literacy tool under the Individuals with Disabilities Education Act. This guidance reaffirms my Administration’s commitment to using Braille to open doors for students who are blind or visually impaired, so every student has a chance to succeed in the classroom and graduate from high school prepared for college and careers.

We have come a long way in our journey toward a more perfect Union, but we still have work ahead. We must fulfill the promise of life, liberty, and the pursuit of happiness and expand the freedom to make of our lives what we will. On this day, we celebrate the accomplishments of our blind and visually impaired citizens, and we recommit to building a Nation where all Americans, including those who are blind or visually impaired, live with the assurance of equal opportunity and equal respect.
By joint resolution approved on October 6, 1964 (Public Law 88-628, as amended), the Congress designated October 15 of each year as “White Cane Safety Day” to recognize the contributions of Americans who are blind or have low vision. Today, let us recommit to ensuring we remain a Nation where all our people, including those with disabilities, have every opportunity to achieve their dreams.

NOW, THEREFORE, I, BARACK OBAMA, President of the United States of America, by virtue of the authority vested in me by the Constitution and the laws of the United States, do hereby proclaim October 15, 2013, as Blind Americans Equality Day. I call upon public officials, business and community leaders, educators, librarians, and Americans across the country to observe this day with appropriate ceremonies, activities, and programs.

IN WITNESS WHEREOF, I have hereunto set my hand this eleventh day of October, in the year of our Lord two thousand thirteen, and of the Independence of the United States of America the two hundred and thirty-eighth.


Final call for submissions: GLIMPSE journal #10 – Blindness

Blindness, Issue #10

Deadline: March 1, 2013

GLIMPSE’s issue on the theme of blindness will investigate interpretations, explanations, and manifestations of blindness through the lenses of science, social science, art, and the humanities. We are interested in writings that tackle blindness as a physical state and/or as a state of mind. Do certain manifestations of blindness disrupt traditional views of a body/mind divide, i.e. cases in which blindness may be psychosomatic? How do individuals classified as “blind” express their blindness to others and, conversely, how do non-blind individuals interpret and make sense of blindness?

From a scientific point of view, how does the brain compensates for physical blindness, and why does blindness often render other senses more acute? How have medical and technological advancements undermined the ‘permanence’ of blindness, and how do these developments change both the lifestyles of those with physical blindness and the discourse surrounding blindness? Indeed, what is the discourse that surrounds blindness, and how is the notion of ‘blindness’ manifested in language (for example: to turn a blind eye; love is blind; to blindside)?

We invite works that cover any of these suggested topics, and also encourage submissions that approach other relevant issues. Submissions may not exceed 2500 words (or 6 pages for non-textual visual submissions). Research articles presented for the layperson, essays, interviews, book and film reviews, and visual works are all welcomed.

Does your work fit? Read our submission guidelines.
