Just remember: 20/40 vision is not bad! It just means you can benefit from corrective lenses. If you'd like to see distant objects and text a little more sharply, it's nothing some new glasses or contacts can't fix. Book an appointment with one of our top-notch optometrists if it's time to recheck those peepers.

A person with 20/40 vision sees things at 20 feet that most people who don't need vision correction can see at 40 feet. This means that they are nearsighted, but only slightly. A person with 20/40 vision may or may not need eyeglasses or contacts, and can discuss his or her options with a doctor.

20/30 to 20/60, this is considered mild vision loss, or near-normal vision. 20/70 to 20/160, this is considered moderate visual impairment, or moderate low vision. 20/200 or worse, this is considered severe visual impairment, or severe low vision.

20/40 vision uncorrected in at least one eye is the vision required to pass many state driving tests (for driving without glasses). 20/50 vision or worse is often the visual reduction that is considered bad enough by most patients to need cataract surgery, if that is the cause of the visual loss.

20/40 vision uncorrected in at least one eye is the vision required to pass many state driving tests (for driving without glasses). 20/50 vision or worse is often the visual reduction that is considered bad enough by most patients to need cataract surgery, if that is the cause of the visual loss.

Visual acuity of 20/40 can be an indication of nearsightedness, meaning your prescription will most likely be a negative value. It is possible for someone with nearsightedness to experience presbyopia or astigmatism as well, so you may require a prescription that corrects multiple refractive errors.
