Kindle Paperwhite fits your needs for large, easy-to-read text. The 7 inch glare-free E Ink screen stays clear on a sunny porch, and the adjustable warm front light keeps brightness gentle at night. Compared with 6 inch models, the larger screen lets you use bigger text with fewer page turns.
The lowest price version shows lock-screen ads and removing them can push it over 150, but the ad-supported model usually stays within budget. Overall it offers strong readability and lighting control for aging eyes.
