Many people enjoy reading a book before bedtime, but often, they only rely on a bedside or desk lamp for illumination. This can be detrimental to your eye health.

The light emitted by bedside and table lamps differs from the direct and uniform light provided by headlamps.

Such indirect lighting fails to meet our visual needs adequately, causing discomfort and making it difficult for both eyes to see clearly. Consequently, this can lead to eye strain and fatigue.

The size of pupils adjusts in response to the intensity of light. Pupils serve as the gateway for light to enter and exit the eye.

When exposed to bright, harsh light, the pupils constrict to protect the eyes from excessive light; in dimmer conditions, the pupils dilate to allow more light in, aiding visibility in the dark.

When reading or studying, the gaze shifts, not solely fixed on our desk, but also across the room.

This constant movement of the pupils and eyeballs can lead to visual fatigue over time, potentially resulting in vision deterioration, dry eyes, eye swelling, pain, and redness.

To prevent these issues, it's essential to adopt healthy eye habits and take a break every 20 minutes of prolonged eye use.

Reading while lying in bed and propping up a book with only your hands can strain your shoulders. Therefore, it's advisable to change your posture periodically, such as lying flat for a moment or shifting to your side.

As your body position changes, the distance between your eyes and the book also varies, which can further contribute to eye strain.

If reading is a must, it's best to sit upright but limit your reading time to 10-20 minutes.

If you like to read at night, always use proper lighting to reduce eye strain.

When children are studying at home, even with the use of eye-friendly lamps, it's important to supplement the lighting with room illumination to minimize the contrast between light and dark areas.

Some people worry about increased energy consumption due to additional lighting. However, with the right choices and responsible usage, this concern can be alleviated.

Consider replacing standard light bulbs with energy-efficient alternatives for efficient lighting.

To promote energy conservation and maintain effective light distribution in your living space, it's imperative to carefully match the size of your lamps with the room's dimensions. Oversized or undersized lamps can hinder these goals.

Additionally, make it a habit to regularly clean dust and debris from your light fixtures, as this will further enhance the overall quality of illumination throughout the room, ensuring a more pleasant and efficient lighting environment.
