Pronunciation: [pˈɜːfɛkt vˈɪʒən] (IPA) 
The phrase "perfect vision" is spelled using the phonetic alphabet as /ˈpɜːfekt ˈvɪʒən/. The first part of the word, "perfect," is pronounced with a long "e" sound in the second syllable (/pərˈfekt/). The second part of the word, "vision," is pronounced with a short "i" sound (/ˈvɪʒən/). This phrase is commonly used to describe someone who has excellent eyesight and can see clearly without the aid of glasses or contacts.
Perfect vision refers to the ideal or optimum condition of visual clarity and acuity, allowing an individual to see clearly and sharply without the aid of corrective lenses or any form of visual assistance. It denotes the ability to perceive objects, details, colors, and shapes accurately and effortlessly, both near and far. A person with perfect vision typically possesses a 20/20 visual acuity, meaning that they can identify objects from a distance of 20 feet just as well as the average person.
In terms of eye health, perfect vision implies the absence of any refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), presbyopia (age-related difficulty in focusing on nearby objects), or astigmatism (distorted vision). The cornea, lens, and retina work harmoniously in a perfectly functioning visual system to promptly transmit clear signals to the brain, resulting in optimal visual perception.
Attaining and maintaining perfect vision can be influenced by various factors, including genetics, age, lifestyle choices, and eye care practices. Preventive measures such as regular eye examinations, proper nutrition, protection from harmful UV rays, and avoiding eye strain caused by excessive screen time or poor lighting conditions, can help preserve and enhance visual acuity.
While perfect vision is an ideal state, it must be acknowledged that it is not a prerequisite for living a fulfilling life. Modern advancements in medical technology and corrective lenses have made it possible for those with vision impairments to enjoy a high quality of life, compensating for any deficiencies in visual acuity.
The word "perfect" originates from the Latin word "perfectus", which means "completed" or "finished". It came from the verb "perficere", meaning "to finish", which is derived from combining the prefix "per" (meaning "through" or "thoroughly") and the verb "facere" (meaning "to do" or "to make").
The word "vision" has its roots in the Latin word "visio", which means "sight" or "seeing". It can be traced back to the verb "videre", meaning "to see".
When the words "perfect" and "vision" are combined to form the phrase "perfect vision", it typically refers to the ability to see clearly without the need for corrective eyewear or any visual impairments.
