Perimeter Trial Lens Set Selection
Spheres The curved surface forms a part of the spherical lens and the dioptric power on all axis positions is the same. After passing through the lens, the light beam focuses on one point (or a virtual focus). Spherical lenses includes concave lenses (-) and convex lenses (+), which are used to examine myopia, hyperopia and presbyopia. Cylinders The curved surface forms a part of the cylindrical lens and the dioptric power on all axis positions is not the same. After passing through the lens, the light beam focuses into a straight line (or a broken line). Cylindrical lenses consists of concave cylindrical lenses and convex cylindrical lenses that are used to examine astigmatism. |
