Kontaktlinsenrezept

Kontaktlinsenrezept, often referred to as a contact lens prescription, is a specific document issued by an eye care professional that details the precise measurements and specifications for custom-made contact lenses. Unlike a glasses prescription, which is for eyewear worn externally, a contact lens prescription is for lenses that sit directly on the surface of the eye. This prescription is crucial for ensuring proper fit, comfort, and optimal vision correction with contact lenses.

The key components of a typical Kontaktlinsenrezept include several parameters. For standard spherical lenses, these are the sphere (SPH), which indicates the power of the lens to correct nearsightedness or farsightedness. The cylinder (CYL) and axis (AX) values are included for toric lenses, which are designed to correct astigmatism. The base curve (BC) specifies the curvature of the back surface of the lens, which needs to match the curvature of the wearer's cornea for a comfortable fit. The diameter (DIA) indicates the size of the lens, ensuring it covers the correct portion of the eye. For multifocal lenses, additional parameters like add power (ADD) are included to correct presbyopia.

Obtaining a Kontaktlinsenrezept involves a comprehensive eye examination by an optometrist or ophthalmologist. This examination includes not only vision testing but also measurements of the eye's surface, such as corneal curvature and pupil size. A fitting session is often part of the process, where the eye care professional will try different lenses to assess fit and comfort. The prescription is valid for a limited period, and regular check-ups are necessary to ensure the health of the eyes and update the prescription as needed. It is illegal to purchase contact lenses without a valid prescription in many regions due to the potential for serious eye damage from improperly fitted or prescribed lenses.
