Difference – Contact Lens & Glasses by Best Optical Shop in Port Louis
Similar to an eyeglass prescription, a prescription for purchasing contact lenses from the best optical store in Port Louis is also needed to correct the refraction error of the eye, be it myopia or near sightedness or hyperopia or far sightedness or even astigmatism.
However, based on the level of the refractive error you have contracted and the kind of lens which has been prescribed, the contact lens prescription will be much different from the ones for the eye glass prescription.
Also, a prescription for contact lens has further additions which are not present for a glasses prescription. These specifications can be ascertained only after the patient gets a thorough contact lens examination and fitting. Those include:
- Base Curve – Abbreviation BC is used for this parameter. The curvature of the back of the lens is determined by this. The shape of the cornea determines the BC. This helps in ensuring a fitting which is neither too loose nor too tightly fitted.
- Diameter – DIA is the abbreviation for this. It is the total size of the lens with its base curve. Usually, this ranges from 13.5 to 14.5 mm. Diameter ranges between 8.5 to 9.5 mm.
- Brand of Lens and Material – Which brand and material of contact lens should be used is also mentioned in the prescription while purchasing from the best optical shop in Port Louis. Every material has a certain level of oxygen permeability.
- Date of Expiry – Most of the contact lenses are active for a year. A doctor’s appointment is needed before the next purchase and the opticians in Mauritius would need that prescription.
Who Can Get this Prescription?
Not every eyeglass user is entitled to this. Many people face conditions like dry eyes and blephartis which need to be checked for before wearing contact lens. There are some individuals who have sensitive corneas and so cannot get acquainted to contact lenses.
A contact lens is always a very sensitive process and should be handled in a very delicate manner to ensure optimum eye safety.
