How to Fill Out and Submit the Confirmation of Legal Blindness Form

The Confirmation of Legal Blindness form is a one-page certification that a qualified eye care professional completes to document that you meet the federal definition of legal blindness. You download it, bring it to your eye doctor, have them record your best-corrected visual acuity and visual field measurements and sign it, then submit copies to whichever agencies or programs you’re claiming benefits from.¹ It isn’t filed with any single central agency, and no fee is involved.

Where to Download the Form

The most widely used version is the free PDF published by the National Federation of the Blind, available on the NFB website.² Several state vocational rehabilitation offices host their own accessible versions with identical content.¹ Print a copy and bring it to your next eye appointment so your doctor can fill it out during the visit. Some eye care providers keep blank copies on hand as well.

What Goes on the Form

The form is divided into a patient section and a certifying authority section. You complete the top: full name, date of birth, and address.

Your eye doctor fills in the clinical data below that:²

Best corrected vision, recorded in three fields labeled OD (right eye), OS (left eye), and OU (both eyes together), using Snellen notation such as 20/200.
Width of visual field, measured in degrees.
Specific eye condition or conditions causing the vision loss — for example, glaucoma, macular degeneration, diabetic retinopathy, or retinitis pigmentosa.

The certifying authority section contains a statement confirming that you are legally blind under the federal definition printed at the top of the form. The doctor signs and dates it, writes their professional title, and either attaches a business card or prints their name, profession, and address.² That’s the whole form. No fee section, no agency tracking number, no attachments required.

The Vision Standards Printed on the Form

The federal definition sets two thresholds, and you qualify under either one:³

Central visual acuity of 20/200 or less in the better eye, with the best correcting lens. A person with 20/200 vision needs to be 20 feet from an object that someone with normal sight can see at 200 feet.
Visual field of 20 degrees or less in the better eye, sometimes called tunnel vision.

Both measurements use the better eye after correction. If your better eye hits either threshold, you meet the definition even if the other eye is normal. The SSA evaluates these criteria under Blue Book Listings 2.02 (loss of central visual acuity) and 2.03 (contraction of visual field).⁴ Listing 2.03 also recognizes a mean deviation of 22 decibels or greater on automated perimetry, or a visual field efficiency of 20 percent or less on kinetic perimetry, which can qualify you where the plain 20-degree diameter test does not capture your field loss.³

Temporary conditions don’t count. The vision loss must be permanent or expected to last at least 12 months. If your acuity can be corrected past 20/200 with glasses or contacts that you can actually wear, you don’t meet the definition. One narrow exception: if contact lenses would correct your vision beyond 20/200 but cause pain, infection, or ulcers that prevent you from wearing them, you still qualify.⁵

Who Can Sign the Form

For most purposes, the certifying professional should be an ophthalmologist or an optometrist. Those are the two types of eye care providers the IRS specifically names when it requires a “certified statement from an eye doctor” for the blindness deduction.⁵ The form itself uses the broader term “certifying authority” without limiting it to those two professions, and some programs accept a wider range of signers. The Library of Congress, for example, accepts certification from doctors, nurses, therapists, social workers, and even professional librarians when enrolling someone in its talking-book service.⁶

The safest approach is to have an ophthalmologist or optometrist complete the form. Their signature satisfies every agency that accepts it. Make sure the doctor includes their full name, profession, and office address, either printed on the form or on an attached business card. That identifying information is what makes the certification verifiable.

Where to Submit the Completed Form

You submit copies to whichever programs you want to access. Make several photocopies before you send anything, and keep the original in your own records.

Social Security Disability or SSI

If you’re applying for Social Security Disability Insurance or Supplemental Security Income based on blindness, the completed form supports your application but doesn’t replace the SSA’s own process. You apply through the SSA — online at ssa.gov, by calling 1-800-772-1213, or in person at a local Social Security office.⁷ The SSA then routes your case to your state’s Disability Determination Services, which reviews your medical evidence and may request records directly from your doctors.⁸ Having the Confirmation of Legal Blindness already completed gives the examiner a clean summary of your diagnosis and measurements.

Before you apply, gather the names, addresses, and phone numbers of every doctor and hospital that has treated your eye condition; the dates and types of treatment; a list of your medications; and a work history covering the last five years.⁸

IRS Additional Standard Deduction

Blind taxpayers get an additional standard deduction on top of the regular one. For tax year 2025, the additional amount is $2,000 if you’re single or head of household, and $1,600 if you’re married or a surviving spouse. These amounts adjust annually for inflation.⁹ If you’re 65 or older and blind, you get the additional amount for each.

You do not attach the Confirmation of Legal Blindness to your tax return. Check the blindness box on Form 1040 or Form 1040-SR and keep the certified statement in your personal records.⁵ If your eye condition is not expected to improve beyond the legal blindness thresholds, the doctor’s statement should say so. That way you won’t need a new certification every year. The IRS only asks to see the statement if your return is examined.

State Vocational Rehabilitation

Every state has a vocational rehabilitation agency that serves people who are blind or visually impaired. In roughly half the states, it’s a standalone agency dedicated to blindness services rather than part of the general VR office. These agencies use the Confirmation of Legal Blindness to determine eligibility for job training, assistive technology, orientation and mobility instruction, and other services. Contact your state’s agency directly for submission instructions, because processes vary.

Library of Congress Talking Books

The National Library Service for the Blind and Print Disabled provides free audiobooks, braille books, and specialized playback equipment. You apply through your local network library, and the application requires certification from a competent authority confirming your eligibility.⁶ A completed Confirmation of Legal Blindness, or the NLS’s own application signed by a certifying authority, satisfies the requirement.

State and Local Benefits

Many states offer property tax exemptions, income tax deductions, free or reduced-fee state identification cards, and reduced admission to state parks for legally blind residents. Benefits and application processes vary widely. Your state’s commission for the blind or department of revenue can tell you what’s available and whether they accept the Confirmation of Legal Blindness form or require their own paperwork.

Common Mistakes That Cause Delays

Most problems with this form come down to incomplete clinical data or unclear professional identification.

Record acuity after correction, not before. The form requires best-corrected vision. If your doctor writes down your unaided acuity, the measurement won’t match the federal definition.
Fill in visual field data when it’s your qualifying criterion. Leaving that field blank when you qualify based on field loss rather than central acuity creates an obvious gap.
Get the doctor’s contact information on the form. A signature without a printed name, profession, and address makes the certification hard to verify. A stapled business card is the simplest fix.
Ask the doctor to note that your condition is not expected to improve. For IRS purposes especially, this means you won’t need fresh certification every year.⁵
Make copies before submitting anything. You’ll likely need the form for more than one program, so keep the original in your records and send photocopies.

One note on paying for the exam itself: most health insurance plans cover medically necessary diagnostic eye testing. Original Medicare does not cover routine eye exams for glasses or contacts, and you pay the full cost for those.¹⁰ A diagnostic exam ordered because of a specific eye condition is generally covered as medically necessary, but confirm with your provider before the appointment.
