Optics is playing an increasing role in industrial research and development, providing a wealth of opportunities for recent graduates and experienced professionals. As many academic physics and electrical engineering departments are placing more emphasis on research and teaching in optics, demand is growing for faculty who are well educated in this area as well.

Because of its interdisciplinary nature, optics allows students to experience a wide range of disciplines through class work, special seminars presented by the faculty, and individual meetings in which students and faculty members can discuss their interests. Students can then specialize in one of several of these disciplines while still in the optics program.

The self-adhesive prism foils are optimally applicable as a temporary solution until the corrective operation. They are also suitable for intermediate use in general conditions (such as diabetes). The high-quality plastic ensures excellent image quality.

How long a prism is needed depends upon your individual needs and your eye condition. Sometimes a prism is needed for several months, but the strength of it changes as your eye condition stabilises.
