Professionally fitted glasses normally correct defects in night vision, 3D vision and color perception. Color perception can be optimized using special filter lenses adapted to each wearer's personal defective color vision. If the lenses are optimally fitted, feature an anti-reflection coating and correct the patient's current refractive status, they make a significant contribution to enhancing color perception. 3D perception and night vision can also be improved by wearing perfectly fitted glasses. It is important that the lenses take all of the eye's visual defects – also known as aberrations – into account. Therefore, it is essential to determine these aberrations right from the outset. The i.Profiler® and lenses featuring i.Scription® technology are ideal for identifying and correcting the aberrations of the eye - and achieve better vision, also in poor light or at night.
Lenses without i.Scription technology correct aberrations only on the basis of the subjective refraction. The refraction values are obtained by using trial lenses, normally in well-lit surroundings. The prescription is therefore suitable for daylight conditions, but not necessarily for night. However, the i.Profiler® also measures the eye with the patient's pupil dilated, therefore imitating night vision, and can obtain the information required in this way. As a result, the lenses obtained provide good vision during daytime conditions as well as correcting poor light or nighttime vision. At the same time, contrast perception is often also increased because halo effects are reduced on the retina.
Although the i.Profiler® cannot sufficiently test color perception because the retina plays a key role here, it has been shown that sharp vision is a must for the perception of rich, saturated colors. This means that more precise lenses also lead to better color perception in many cases.
