What does IF mean in the view of view?
When we perform an examination of view, it is common to come across various acronyms and technical terms that can leave us confused. One of the most common acronyms is FHS, which means sphere. In this article, we will explain what FHS means in the view of view and how this term is used by ophthalmic professionals.
What is FH?
FHS is the abbreviation of sphere, which is one of the measures used to evaluate a person’s visual acuity. The sphere is responsible for correcting myopia -related vision problems (difficulty seeing from afar) and hyperopia (difficulty seeing closely).
When we perform an examination of view, the ophthalmologist uses a table called “Snellen Table” to evaluate the patient’s visual acuity. This table consists of letters of different sizes, and the patient should read the letters to a certain distance.
How is the FHS measurement?
FHS measurement is done in dioptrias, which is the unit of measurement used to correct vision problems. When the ophthalmologist identifies that the patient has myopia, he prescribes a negative lens (with negative ESF value) to correct the problem. In the case of hyperopia, a positive lens (with positive bud value) is prescribed.
It is important to note that the FHS is just one of the measures used in the view of view. In addition to the sphere, other parameters are also evaluated, such as the cylinder (responsible for correcting astigmatism) and the axis (which indicates the orientation of astigmatism).
Conclusion
The acronym in the examination of view means sphere, which is one of the measures used to correct vision problems related to myopia and hyperopia. It is important to perform ophthalmic exams regularly to identify and correct any vision problem, thus ensuring good quality of life and visual well-being.
