Question

Which measure would the nurse recommend for a client who needs to reduce glare? a. Use of fluorescent lighting in the home b. Use of 60-watt bulb in a lamp directly aimed at the reading surface c. Use of a hand-held magnifier d. Use of a yellow plastic overlay for reading

Short answer

Option D: Use of a yellow plastic overlay for reading.

Step-by-step solution

Understand Glare Reduction

Glare can cause discomfort and difficulty in seeing clearly. It is essential to choose lighting or tools that minimize bright reflections and harsh light.

Analyze Option A

Fluorescent lighting can be harsh and may not effectively reduce glare. It might create reflections and enhance direct light intensity, making it uncomfortable for reading or other activities.

Analyze Option B

Using a 60-watt bulb directly aimed at the reading surface would create a bright spot, leading to intense reflections and increased glare, which is not recommended for reducing glare.

Analyze Option C

A hand-held magnifier is used to enlarge text or objects but does not address glare. It focuses on improving visibility through magnification but can intensify glare if not used with proper lighting.

Analyze Option D

A yellow plastic overlay is designed to reduce glare and improve contrast while reading. It filters out certain wavelengths of light, minimizing glare and easing eye strain. This is an effective method to reduce glare.

Make a Recommendation

Based on the analysis, the use of a yellow plastic overlay (Option D) is the most effective measure to reduce glare for the client.

Key concepts

lighting adjustments

Lighting adjustments play a crucial role in reducing glare and enhancing visual comfort. To effectively reduce glare, it is important to avoid harsh and direct light sources, such as fluorescent lighting or bulbs aimed directly at the reading surface. Instead, opt for ambient lighting that provides a soft and even distribution of light.
Using lamps with diffusers or shades can help to spread the light evenly and prevent harsh reflections. Adjusting the positioning of lights can also minimize direct eye exposure to bright light sources. For a more comfortable reading experience, consider using natural light where possible, as it is generally softer and less likely to cause glare. If using artificial light, ensure it is adequately diffused and positioned to avoid direct reflection or bright spots.
Here are some practical tips for lighting adjustments:

• Use lamps with adjustable brightness levels.
• Position lights to the side rather than directly in front.
• Incorporate indirect lighting, such as floor lamps or wall sconces.
• Avoid shiny surfaces that can reflect light and cause glare.

visual comfort

Visual comfort is an essential aspect of creating an optimal reading or working environment. Reducing glare is one part of achieving visual comfort, but there are other factors to consider.
Eye strain can result from working in poorly lit environments or looking at excessively bright screens. To enhance visual comfort, make use of lighting options that provide consistent, gentle illumination. Adjusting the brightness of screens and monitors to match the ambient lighting can also contribute to eye comfort.
Proper seating and posture are important, as they affect how light interacts with the reading or working surface. Ensuring that one’s seating position does not create shadows or introduce glare can help maintain visual comfort for extended periods. Additionally, taking regular breaks to rest the eyes can mitigate strain and fatigue.
Consider the following recommendations for maintaining visual comfort:

• Use adjustable and anti-glare screens for digital devices.
• Ensure adequate backlighting for screens to reduce contrast strain.
• Keep the reading material at an appropriate distance and angle.
• Take frequent breaks to give eyes time to rest.

reading aids

Reading aids are tools designed to enhance visibility and reduce eye strain while reading. These aids can be particularly beneficial for individuals experiencing difficulty due to glare or other visual challenges.
One of the most effective reading aids for reducing glare is the use of yellow plastic overlays. These overlays help by filtering out specific wavelengths of light that contribute to glare, thus providing a clearer and more comfortable reading experience.
Other reading aids include hand-held magnifiers, which enlarge text or objects, making them easier to see. However, magnifiers should be used in combination with proper lighting to prevent intensifying any existing glare. Another helpful tool could be anti-glare reading glasses, which are designed to reduce the reflection of light and make reading more comfortable.
Here are some reading aids and their benefits:

• Yellow plastic overlays: Reduce glare and improve contrast while reading.
• Hand-held magnifiers: Enhance text size for better visibility.
• Anti-glare reading glasses: Minimize reflections and ease eye strain.
• Adjustable reading lamps: Provide focused light without causing harsh reflections.
