Most people expect a few changes in their eyesight as they age. Changes in eyesight are so common that racks of inexpensive reading glasses in a series of strengths stand in most any variety or drugstore.
One of the unexpected changes that can happen to the aging eye includes the color yellow. For some people the lens of the eye becomes increasingly dense and more yellow with age. With that change, contrast sensitivity declines and dark colors can be difficult to distinguish from each other.
The yellowing effect may not be affecting you personally, but if you are a retailer or manufacturer selling products, how your products are being perceived by the older customer with this condition affects your sales.
Yellow labels can “disappear” against a bright yellow background. Decreased contrast sensitivity can cause blue and black or blue and green to appear the same. White or light colored type on a black or dark colored background may be almost impossible to read for that customer.
Colors not only affect people differently because of personal and cultural conditioning and experiences. The visual abilities of each person affects how and if they perceive a color. Keeping in mind the possibility for differences in color perceptions is especially important for color consultants. Yellow is not always a sunny color.
