1 Moderate visual impairment. Visual acuity <= 0.3 > 0.1. 2 Severe visual impairment. Visual acuity <= 0.1 > 0.05. Blindness.Decimal: The visual acuity can be expressed in decimal or percentage for example 0.8 (80%), 1.0 (100%), or 1.2 (120%). In this system, 1.0 or 100% means the average vision, 2.0 or 200 % is the highest possible value and indicates very sharp, way above-average vision.If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet. Having 20/20 vision does not necessarily mean you have perfect vision.
What does 20/20 vision mean : If you have 20/20 vision, you can see an object that is 20 feet away clearly. The term refers to average, normal vision. If your vision doesn't measure 20/20, you may need to wear contact lenses or glasses to see clearly.

Blindness as defined by the law: glasses improve visual acuity (far sight and near sight) by no more than 2% (Vision 0.02); one's visual capacity is so strongly disrupted by restrictions to one's field of vision that the resultant limitation of a visual acuity reduction is equivalent to 2%.
Is 1.0 normal eyesight : What is normal visual acuity Visual acuity varies from person to person and there is no "normal case". Visual acuity also changes with age: a Visus value of 1.0 to 1.6 is often considered optimal for a 20-year-old, and 0.6 to 1.0 for 80-year-olds.
So +1.00 and -1.00 are quite modest; your eyesight isn't too bad, as you only need 1 diopter of correction. On the other hand, +4.50 and -4.50 represent a greater lack of clarity; you'll need a stronger prescription, at 4.5 diopters of correction. Legal Blindness FAQs
They may also struggle to focus when they're in a group of people or when there isn't enough light. A 20/80 vision profile is commonly referred to as nearsightedness. Is minus 7 legally blind A legally blind prescription is anything that's lower than -2.5, which is the equivalent of 20/200 vision.

For example, if your prescription says -1.00, you have one diopter of nearsightedness. This is a fairly mild amount of nearsightedness. If you are -4.25, that means you have 4 and 1/4 diopters of nearsightedness. This is more nearsighted than -1.00 and requires stronger (thicker) lenses.In Europe, vision is measured in meters in a 6/6 meters format, which is pretty close to 20 ft. In Asia, it measured as a fraction. 1.0 vision is 20/20, 1.33 is 20/15, or a bit better than average, 0.5 is 20/40, or a bit worse than average.Before we jump into what each section of how to read an eye prescription means, as a general rule, the higher the numbers on your prescription, the worse your eyesight is and the stronger your prescription will be to provide the necessary correction. Mild: -0.50 to -3. Moderate: -3.25 to -5.00. High: -5.25 to -10. Although there are some differences in visual acuity standards for each inspection institution, in order to drive a car, the corrected visual acuity needs to be 0.7 or better with both eyes, 0.3 or better with a single eye, and if the vision is less than 0.3 in one eye, the vision in the other eye needs to be 0.7 or …
Is 2.00 legally blind : Visual acuity of 20/200 or less in the better-seeing eye with the best conventional correction (meaning with regular glasses or contact lenses). This is a 20/200 visual acuity measurement, correlated with the Snellen Eye Chart (pictured at left):
Is 2.0 bad vision : For the nearsighted, the American Optometric Association (AOA) has determined the following levels of severity: If your number is between -0.25 and -2.00, you have mild nearsightedness. If your number is between -2.25 and -5.00, you have moderate nearsightedness.
Is 0.5 eyesight bad
Most people with glasses are nearsighted, which is why there is more talk about “negative vision scale” and negative vision numbers. Nearsightedness is categorized into mild, moderate, high, and extreme: Mild: -0.50 to -3. Moderate: -3.25 to -5.00. A legally blind prescription is anything that's lower than -2.5, which is the equivalent of 20/200 vision. Visual acuity is directly linked to a prescription level. So, for example, visual acuity of -4.0 means you have 20/400 vision.Identify a – sign: Negative numbers, such as -1.00, indicate the lens strength needed to correct shortsightedness. Shortsightedness is when a person can see close things but distant objects appear blurry. A large number: Whether a + or -, a large number indicates a stronger prescription.
What does 0.00 eye prescription mean : The Numbers
Sometimes diopter is abbreviated to “D.” On a glasses prescription, 0.00 (zero focusing power needed) represents good vision. Generally, the further away from zero you go (whether the number is positive or negative), the worse your eyesight and the greater the need for vision correction.
