Selection of Contact Lenses with the Issuance of a Prescription in the Chain Dim Optics

Vision diagnostics involves testing visual acuity, computer diagnostics and selection of optimal correction. Visual acuity is checked subjectively, separately for each eye, using a sign projector of different sizes. As a rule, with myopia (myopia), distance vision is significantly reduced; with age-related farsightedness (pressbyopia), it can remain one hundred percent.

Computer vision diagnostics are carried out using an automatic refractokeratometer POTEC, which objectively and quickly determines the type and degree of refractive error of the eye (myopia, farsightedness, astigmatism). This test does not determine fundus conditions or measure intraocular pressure. It is the best help for the correct and accurate selection of contact correction. In children, it is preferable to do this with preliminary dilation of the pupil.

When selecting contact lenses, in addition to diagnosing vision and determining correction, the services of an ophthalmologist also include a slit-lamp examination (biomicroscopy), where the condition of the anterior segment of the eye is assessed under high magnification. This is necessary to determine the condition of the cornea and conjunctiva, identify contraindications for wearing lenses, possible inflammatory or allergic complications, assess the fit of the lens on the eye, as well as identify dry eye syndrome, etc.

The selection of lenses ends with training, during which detailed instructions are given on how to put on and remove lenses, how to care for them and what to avoid. If necessary, it is possible to return to the doctor for additional consultations, clarification of details, re-examination of vision or eye condition.

Regular clients of the Dim Optics salons can also get advice in case of problems with the anterior part of the eye.
