Why do blind people have to wear dark shades?

It is not true that blind people have to wear dark shades. Some blind individuals choose to wear dark sunglasses or other eye protection for various reasons, but it's certainly not a requirement. Here's why some blind individuals may choose to wear dark shades:

Light Sensitivity: Some visually impaired individuals may have light-sensitive eyes or certain eye conditions that make them sensitive to bright light. Wearing dark shades can help reduce the amount of light entering their eyes, providing comfort and protection.

Glare Reduction: Bright sunlight or artificial light can cause glare, making it challenging for individuals with visual impairments to see effectively. Dark glasses help reduce the intensity of glare and improve overall vision in bright conditions.

Eye Alignment: In some cases, blind individuals may have eye conditions that affect their eye alignment or cause constant eye movement (nystagmus). Wearing dark shades can conceal these eye movements and provide a sense of normalcy.

Style and Personal Preference: Just like anyone else, blind individuals have their own style preferences. Some may choose to wear dark sunglasses as a fashion accessory, while others may find them comfortable or suitable for their daily activities.

Privacy and Social Comfort: Some blind people may choose to wear sunglasses to give them more privacy and confidence in social situations. It's important to note that not all blind individuals wear dark shades, and it's not required for them to do so. Each person's needs and preferences may differ.
