SeniorView -Elderly Vision Simulator-



SeniorView: Elderly Vision Simulator

SeniorView enables you to experience the visibility of the color world seen by the elderly. Thus, you can understand the difficulties that aged people suffer in their daily lives. In addition, you can improve your color designs for all ages by using Senior View even though you are not part of the elderly. Furthermore, you can create true universal color designs considering color deficiency too by using it together with Variantor.

     

The filters of SeniorView can precisely simulate the spectral transmittance of an aged human lens. They were designed based on a two-factor model so that the human lens of the standard 32 years old person with healthy eyes can virtually be replaced for the human lens of the standard 75 years old person with healthy yellowish eyes.

The relationship between a young observer of age X and an elderly person of age Y is shown below.
