What Does Visual Impairment Mean?
Visual impairment affects millions of people worldwide in many different ways.
Understanding the different types of visual impairment and learning respectful ways to help can make a meaningful difference in someone's daily life.
Low Vision
Visual impairment exists on a spectrum, ranging from mild vision loss to complete blindness. Low vision refers to significant visual impairment that cannot be fully corrected with glasses, contact lenses, medication, or surgery. People with low vision may have difficulty reading, recognizing faces, or navigating spaces, but retain some usable sight.
Central and Peripheral Vision Loss
Central vision loss, often caused by conditions like macular degeneration, affects the center of the visual field. People with this condition may struggle to read or see fine details but can often navigate using their peripheral vision. Conversely, peripheral vision loss, common in conditions like glaucoma or retinitis pigmentosa, creates tunnel vision where only the central field remains clear.
Blurred and Distorted Vision
Blurred vision can result from various conditions including uncorrected refractive errors, cataracts, or diabetic retinopathy. Some individuals experience clouded or hazy vision, while others may have blind spots or distorted vision that makes straight lines appear wavy.
Total Blindness
Total blindness, where no light perception exists, represents a small percentage of visual impairment cases. Many people classified as legally blind actually have some remaining vision they can utilize.
How to Provide Helpful Assistance
- Always Ask First: The golden rule when assisting someone with visual impairment is simple: always ask first. Never assume someone needs help or grab their arm without permission. A simple "Would you like assistance?" respects their autonomy and expertise in navigating their own needs.
- Offering Guidance: When offering your arm for guidance, allow them to take your elbow or shoulder rather than pushing or pulling them. Walk slightly ahead and describe upcoming obstacles, such as "Steps going down in three paces" or "Doorway ahead on the right." Be specific rather than using vague terms like "over there."
- Communication Tips: In conversation, don't hesitate to use common phrases like "see you later" or "nice to see you." These expressions are part of everyday language, and avoiding them can feel more awkward than natural. Do speak directly to the person rather than addressing their companion, and identify yourself when approaching, especially in group settings.
- Giving Clear Directions: When giving directions, be precise. Instead of saying "the office is that way," try "the office is about twenty feet ahead on your left, past the water cooler." Avoid rearranging furniture or objects without informing someone who is visually impaired, as they rely on spatial memory and consistency.
- Practical Considerations: If you're guiding someone to a seat, place their hand on the back or arm of the chair and let them seat themselves. When leaving a conversation, always announce your departure so they're not left speaking to an empty room.
Remember that service animals are working and should never be petted, fed, or distracted without the handler's explicit permission. These animals require focus to perform their critical tasks safely.
