Cylindrical Eye Power

About "Cylindrical Eye Power"

If a person is said to have cylindrical eye power, they have what is known as astigmatism, a refractive error. It means that the correction required is unequal in different meridians of the eye. So, they will need a spectacle lens with a cylinder power correction in addition to the spherical power correction.

What the Numbers on Your Spectacle Prescription Indicate
Article Overview: The recent trend of an increase in near-vision work, be it on the Android phone, laptops or on paper has caused us to see the number of myopic patients go upward. This shocking trend can be seen by as much as 50 % of the students in higher primary to pre-university being prescribed glasses for low to moderate myopia. With such an ample number of customers, optical shops and smaller spectacle outlets more often than not, are forced to employ untrained or inexperienced labor to cut costs. It is the right of a patient to be fully aware of what modality and magnitude of treatment s/he is being offered and its relevant aspects. This article has been written with an aim to shed light on the various measurements and their meanings in practical terms to the average spectacle wearer, so that the next time s/he is in a tough spot, s/he will have at least some knowledge and basic understanding of his condition rather than simply taking the word of the optical shop owner and his workers.  Read Article »
