There are 2.2 billion people living with visual impairment globally. Some are living with inherited retinal diseases that are progressive and can lead to complete blindness. Up until recent years, blind and visually impaired people were told that no treatment is available. This is changing as genetic testing is paving the way for a surge of gene therapies.

As people age, they often experience a number of changes in their physical, mental and social health. Among these are eye and ear changes, and diseases that usually result in vision and hearing loss. Changes to our eyes and ears occur as a result of disease, genetic factors, “wear and tear” and environmental factors.

EVERYTHING seems to stiffen up as people age, and our eyes are no exception. As the years go by, the lens of the eye becomes harder and less elastic. The result is a gradual worsening of the ability to focus on objects up close, called presbyopia.
Here is a clear plea, written in legible 12-point type, from middle-aged women to package designers.

make the first move
prove we are
just like everyone else
