subject: Proper Lighting Makes Your Eyes Be Away From Disorders [print this page] As known to all, eye disorders are caused by many incorrect actions such as wrong posture and bad reading habits, and bad lighting plays a quite vital role in causing eyesight to decrease.
First, we should come into a common sense that our eyes will not easily get tired with right lighting and with less eye using, muscles cant be fatigued in that way. So reading in good circumstances makes great sense.
Even though many years ago we have achieve the goal that everyone owns bright and enough light, a majority of people have a great willing to choose lights considering its decorative value rather than its healthy value nowadays. Many factories produced more and more complicated lighting fixtures regardless of their utility value. In addition, false directing of consumption makes people to take decorative value into consideration primarily without doubt. But are there lighting fixtures with both decorative value and utility value? Or can people buy some lights good for reading in the study room?
Many lighting companies provide free services in guide of which kind of lighting fixture meets your need and you can also get information about which to choose on the internet. So consider more before you decide to buy to lighters so as to make sure you can get the right light.
I think both light producers and human-beings should attach importance to environment - friendly lighting fixtures.
Enough Light
Sit with right posture, let the light come over your left shoulder and fall directly on the page, never read facing a direct light.
When read by artificial light, youd better choose a tall table lamp with a 150-watt bulb more or less. Place the lamp on the left corner of table and make sure the reflected glare does not directly go into your eyes. How to know whether the light goes directly into your eyes? Here is a simple instruction you can follow: put a small pocket mirror on the paper and observe whether theres a light bulb in the mirror; if you can see the bulb, move the lamp until you cannot see the light bulb in the mirror.
Good general illumination in the room is of great importance, too. So not only the lamp matters, but also the color of wall does. Light colors reflect light and make room brighter while dark colors absorb light and make room darker. So choose a right color and you can benefit from it. Furthermore, the color of draperies and upholstery of furniture also affects the brightness. It seems that you should devote more energy on choosing everything.
Besides, dont just turn on a reading lamp and turn off other lamps, because when the whole room is as bright as the page, your eyes are the most laborsaving.
No Glare
As glare causes eyestrain, so youd better read in the steady light instead of the flare one.
Remember the suggestions above by heart, and you will certainly benefit from them.
