Convexo-concave

Convexo-concave describes a lens or other object that possesses a shape exhibiting both convex (outwardly curved) and concave (inwardly curved) surfaces. This dual curvature is crucial for focusing or diverging light depending on the specific design and refractive index of the material. The lens is thicker in the middle and thinner towards the edges. This shape is also employed in various contexts outside of optics, such as in specific anatomical structures or mechanical components where the shape is useful for specific purposes. This hybrid structure offers unique advantages for diverse applications, including vision correction and structural support.

Convexo-concave meaning with examples

• The optician prescribed glasses with convexo-concave lenses to correct my nearsightedness. The design allowed for both refraction of light entering the eye and focus. The lenses corrected the curvature. The blended structure provides clear vision at varying distances. They were effective in focusing images correctly on the retina.
• The meniscus, a fibrocartilaginous structure in the knee, can be described as convexo-concave due to its shape. The cartilage design is thick at the edges and thin in the middle. This configuration provides stability, load distribution, and lubrication within the joint. Its unique geometry cushions the knee, providing support to the wearer.
• Engineers designed the new bridge supports using a convexo-concave profile to enhance its structural integrity. The curved shape helped distribute weight evenly, increasing the span the bridge could cover. The geometry offered increased stability and could withstand higher loads. The design ensured the support system was sturdy.
• The specialized contact lens used a convexo-concave design to counteract astigmatism. This configuration corrected the visual distortion. The hybrid lens allowed for improved vision, particularly for individuals with corneal irregularities. The lenses were extremely effective. They were a perfect shape to match their patient.
