IRS Tax Topic 551 - https://www.irs.gov/taxtopics/tc551
Additional Standard Deduction – You're allowed an additional deduction if you're age 65 or older at the end of the tax year. You're considered to be 65 on the day before your 65th birthday (for tax year 2023, you're considered to be 65 if you were born before January 2, 1959). You're allowed an additional deduction for blindness if you're blind on the last day of the tax year. For example, a single taxpayer who is age 65 and blind would be entitled to a basic standard deduction and an additional standard deduction equal to the sum of the additional amounts for both age and blindness. For the definition of blindness, refer to Publication 501, Dependents, Standard Deduction, and Filing Information. If you or your spouse were age 65 or older or blind at the end of the year, be sure to claim an additional standard deduction by checking the appropriate boxes for age or blindness on Form 1040, U.S. Individual Income Tax Return or Form 1040-SR, U.S. Tax Return for Seniors.
