We Assure You Better Eyesight and a Clearer Tomorrow

There are three different parameters which need to be tested when it comes to eye testing. Now all these tests could be carried out with the help of lenses which are either spherical, cylindrical or axis type. These lenses come in trail cases where they could be stored in a large numbers. At Unitech Vision we have Optical Trial Lens Set manufacturer and supplier in India for ophthalmic instruments. We have a range of Trial lenses set. These trial lenses set are of different types and include deluxe trial case in leather briefcase, the illuminated trial case with wooden box golden silver, Illuminated trail case with wooden box red and black. The deluxe model contains around 225 lenses consisting of spherical lenses of +/_32 pairs. The wooden box also contains 20 pairs of cylindrical lenses, 10 prisms and seven accessories. All these lenses are reduced aperture lenses fitted in nodi zed metal mounts.

Every lens whether spherical or cylindrical in nature has a specific role. In case of a purely spherical lens it is useful for correcting near sightness or farsightedness. So individuals who have this only as a problem will need to create this lens. Here we are discussing about a simple convex lens for farsightedness or concave lens for nearsightedness calculation. This number tells us the corrective power of a lens. The positive numbers are for farsightedness and the negative numbers are for the nearsightedness. The unit of measurement is diopter.

Those individuals who have an irregular shaped corenea or have different internal lens of their eyes will

require the cylindrical lenses. Corrective lenses may need to vary in thickness across its surface rather than being symmetrical. Mostly the cylinder number is the amount of correction for astigmatism and is measured in diopters like the spherical lenses.

The axis parameter is another important factor while checking the eyes. The degrees are measured from zero degrees to one hundred eighty degrees. Axis indicates the orientation of astigmatism. In case the person’s eye is oblong, like an American football, the axis tells us how to rotate it to best represent the eye we're talking about. Unitech Vision is one such platform where you could find almost all the medical ranges and medical equipment required for eye and ear surgery.
