Over time, our eyes become more sensitive and react more strongly to light. It is therefore necessary to do some adjustment in the lighting of the house in order to maintain a good quality of life and sight. Space can become more comfortable even when the signt changes with age.
How does the perception of light change with age?
Changes in vision can occur throughout life, but once you reach a certain age, these changes become even more worrying than simply not seeing objects from a distance. Just like the rest of the body, some muscles of the eye begin to weaken. Have you ever shined a light in one eye and watched the pupil dilate? The muscles involved in this phenomenon are intended to control the quality of the light collected and, as we get older, they find themselves lagging in their reaction time. This implies that the eyes take longer to adapt to dark or bright environments. Other changes may occur such as yellowing of the lens that affects the perception of colors, the appearance of spots or “floating” in the vision caused by particles in the vitreous of the eye and cataracts that cause areas of fog in the eyes. Medical measures may be takento repair these phenomena or improve these conditions, but good lighting may also help to compensate for some of these eye disorders.
What kind of light should be installed to adapt to these changes?
The troubled vision due to age can often be solved by simply using more light than usual. This does not necessarily mean that you have to raise the brightness of all the lighting in your home to extreme levels, but you can use bright lights for some tasks, such as table lamps, floor lamps, lighting under cupboards to provide more lighting for activities such as cooking, reading or using the bathroom mirror, etc. That being said, it’s not necessarily a bad idea to increase the general level of lighting in your home.
As mentioned above, older eyes have difficulty adjusting to different levels of light as quickly as before. In order to bring as much comfort as possible to the eyes, you need to set up uniform ambient lighting throughout the house. This means that no room should be brighter or darker than another, so there must be smooth transitions from one room to another. The addition of dimmers (dimmers) can also make it easier to adjust light levels in different rooms.
The glare of the extremely powerful light emitted by the light bulbs can trigger vision problems and even worse, “eye floaters”. These eye floaters and other eye injuries can cause light scattering in the eye. This increases the sensitivity to glare, which is not the case for low light levels. To avoid glare, make sure your light sources are shaded or not directed directly to the eyes. For example, you can use spots with frosted lenses to hide the light source.
Precision of color
Because the coloring of lenses on the eyes may change, it is important that light sources have a very high CRI or CRI (Color Rendering Index) – usually above 80 – for colors to be more authentic.
