What is astigmatism and how to choose the right glasses?

Astigmatism is a vision defect - like far-sightedness or myopia. Astigmatism is corrected by cylindrical lenses with properly selected axis. Ophthalmologist should put these two values ​on prescription.

On the prescription are usually two tables of values. At the top of prescription usual are given D.V. - which means Distance Vision, and to a bottom are usual N.V. (Near Vision) values for near vision. Your ophthalmologists or optometrists should always put on prescription P.D. - which means Pupil Distance.

How do I know which index lens to choose?

We have several indexes of lenses (or lens thickness) correction. The higher the index is the lens is thinner. Standard thickness index is 1.50, which is done most of the glasses. We often make the glasses in the index 1.60 - even with small powers. They are more esthetic and lighter by about 25%. The next step is an index of 1.67, which is 35% thinner. Depending on the power of the lens can be thiner to reduce its weight to a maximum index of 1.74 or up to 50% in the lens of plastic and even index 1.90 - that is, up to 60% but in this case it will be necessary to mount glass lens - which will be thinner but will be more fragile, because made of glass. The weight of such lenses 1.90 will also be heavier because the glass itself is heavier - but if you depend on the maximum thinning it will be the best solution. There are polycarbonate lenses called lens Trixex otherwise called PNX lenses. This is a special material to 10x more resistant to cracking and breaking! NOTE: PNX is not suitable for washing in ultrasonic cleaners!
