Around 300 million people worldwide experience some form of color blindness, with the condition significantly more common in men (about 1 in 12, or 8%) than women (around 1 in 200, or 0.5%). This genetic trait, usually affecting red-green perception, is passed down through the X chromosome, making males far more susceptible.

No, a -7 prescription doesn't automatically mean someone is legally blind; legal blindness depends on your best-corrected vision (with glasses/contacts), not the prescription number itself, meaning you're legally blind if you have 20/200 vision or worse in your better eye even with correction, or a very narrow visual field. While -7 indicates severe nearsightedness, it's often correctable to normal vision, so you'd only be legally blind if after correction, your vision remains at or below 20/200 or you have significant peripheral vision loss.

The 24-hour rule for ADHD is a self-regulation strategy to combat impulsivity by creating a mandatory waiting period (often a full day) before reacting to emotionally charged situations or making significant decisions, allowing time for reflection and reducing regretful snap judgments, especially for things like impulse purchases or arguments. It's a pause button that gives the brain space to process, move from impulse to intention, and evaluate choices more logically, helping manage ADHD's impact on emotional regulation and decision-making.
Vision Australia defines the two terms as follows: Legally Blind A person is considered legally blind if they cannot see at six metres what someone with normal vision can see at 60 metres or if their field of vision is less than 20 degrees in diameter.
