Is 1.25 eye prescription bad?
1.25 power lens correction is relatively mild. When it comes to corrective vision wear, the further from zero the number, the worse a person’s sight. In cases where a person receives a diagnosis of 2.25 or 3.00 or higher number, prescription glasses are needed to correct the problem. …
Is 4.25 eyesight bad?
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. Similarly, +1.00 would be a small amount of farsightedness and +5 would be more.

Having a 20/200 visual acuity means the smallest letters that you’ll identify from the chart by standing 20 feet away from it will be equal to the size of the smallest letters a person with “normal vision” would be able to identify at a distance of 200 feet from the chart.
What does 20 100 eyesight look like?
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.
Is 2.75 eyesight bad?
If you have a minus number, like -2.75, it means you’re short-sighted and find it more difficult to focus on distant objects. A plus number indicates long-sightedness, so objects up close appear more blurred or close vision is more tiring on the eyes.
Is 1.00 eye prescription bad?
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. So +1.00 and -1.00 are quite modest; your eyesight isn’t too bad, as you only need 1 diopter of correction.

How bad does your prescription have to be blind?
First: What does it mean to be “legally blind?” In most states, if you have distance visual acuity less than 20/200 that is not correctable with glasses/contact lenses, you are legally considered to be “severely visually handicapped” (which used to be called “legally blind”).
