 On the planet, over 90 percent of the population 45 years and older have difficulty reading, but their distance vision is OK. The current bifocal lenses are divided ... so when people are driving they are not using the bifocal lens. Our lens, with the focusing power, allows them to use the whole lens for different vision tasks at the same time. |
| People can use the whole field of the lens to see objects. |
| The field of view is limited in such bifocal eyeglasses, requiring the user to gaze down to accomplish near visions tasks and in some cases causing dizziness and discomfort. In stimulated and actual human vision tests, the new lens performed well at both near and far focusing tasks. These results represent a significant advance in vision care. |
| This makes them safe to use for driving. |
| We want to improve the quality of life for a large population. |
| When it's on it has focusing power that can be used for reading. When it's off, it has no focusing power—it's just like a piece of glass—and can be used for driving and seeing far off things. |
