Our expert eye doctors, Dr. Tacker and Dr. Worley, are committed to providing you with the best vision possible.
They will perform a detailed eye exam to check your eyesight, in our Corsicana, Texas, office. This includes a thorough eye test to determine your vision prescription for eyeglasses and contact lenses. In general, an accurate vision prescription aims to give you 20/20 vision. What does that number mean, and is it really the best vision?
What does 20/20 and all those numbers mean?
The standard by which all eyesight is judged is referred to as 20/20 vision. This is regarded as “normal vision” and describes what someone should see when standing 20 feet away from an eye chart.
If you are diagnosed with 20/40 vision, it means that at 20 feet – you can only see the details that a person with normal vision sees at 40 feet. In reverse, if you have 20/10 vision, it means that at 20 feet – you can clearly see what most people can only see at 10 feet. That makes your vision better than the average standards!
Can people have better than 20/20 vision?
20/10 vision is thought to be the maximum visual acuity of human eyes without binoculars or other magnifying devices. Recent advances in optics have led to the creation of corrective lenses that can provide this ultra-sharp vision.
It seems that the best eyesight ever reported in a human was in an Aborigine man with 20/5 vision! To give you an idea of how clear and far he could see, his vision measurement compares to the natural sight of eagles. From 20 feet, he could perceive the fine details that most people can only see from 5 feet away! (In case you were wondering, the only creature with vision sharper than an eagle is believed to be the hawk, with 20/2 visual acuity.)
Do we prescribe eyewear for vision higher than 20/20?
Although it’s possible to fit eyeglasses and contact lenses that give sharper than average vision, the gold standard in optometry is still 20/20.
A prescription for 20/10 will certainly improve distance vision, yet it may compromise near vision. In our Corsicana optical center, our experienced optometrist will check your visual acuity carefully. Using high-tech diagnostics, we’ll ensure that you receive the best vision prescription for your ocular condition and lifestyle needs.
While we don’t promise eyesight like an eagle or hawk, at Envision Eyecare we are dedicated to fitting our patients with the sharpest vision possible for humans!

-
Vision Prescription and Eye Exam: Envision Eyecare emphasizes the importance of a detailed eye exam conducted by their expert eye doctors. This exam includes a thorough eye test to determine the vision prescription for eyeglasses and contact lenses. The goal is to provide patients with the best vision possible.
-
20/20 Vision Definition: The term "20/20 vision" serves as the standard for normal vision. It denotes what an individual should see when standing 20 feet away from an eye chart. If diagnosed with 20/40 vision, it means seeing details at 20 feet that a person with normal vision sees at 40 feet, and vice versa for 20/10 vision.
-
Visual Acuity Measurement: The article explains the measurement of visual acuity, where 20/10 vision is considered exceptional, allowing someone to see at 20 feet what most people can only see at 10 feet. The pinnacle of reported human vision is an Aborigine man with 20/5 vision, comparable to the natural sight of eagles.
-
Maximum Human Visual Acuity: Advances in optics have led to corrective lenses that can provide ultra-sharp vision. While 20/10 vision is considered excellent, it's noted that an Aborigine man with 20/5 vision had vision comparable to eagles, and hawks are believed to have even sharper vision at 20/2.
-
Eyewear Prescription Beyond 20/20: The article addresses the possibility of fitting eyeglasses and contact lenses for vision sharper than 20/20. However, the gold standard in optometry remains 20/20. A prescription for 20/10 may improve distance vision but could compromise near vision.
-
