Comparing glasses for aging-related reading difficulty
Part of Eyes & vision clinical trials.
This study compares two types of glasses (single-vision vs. progressive lenses) to see which one helps people with aging-related reading difficulty (presbyopia) see better and feel better in daily life. You may qualify if you are 40–70 and have trouble reading up close but haven't used reading glasses recently.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 40 and 70 years old.
- Your distance eyeglass prescription is mild (farsightedness or nearsightedness up to 2 diopters, or astigmatism less than 2 diopters).
- You have trouble reading small print at arm's length, and a magnifying lens helps you see better.
- You have not used reading glasses, bifocals, or progressive lenses for near vision in the past 6 months.
- You have no serious eye diseases or eye surgery that changed your prescription.

This study compares multifocal contact lenses to single vision lenses and reading glasses for people over 40 who need help seeing up close. It aims to find which option provides a better experience for presbyopia (age-related blurry near vision).
This study tests a new device called Opti-K that helps people see better up close without needing reading glasses. It may be an option if you are over 40, have had cataract surgery or no significant cataracts, and rely on reading glasses for near tasks.
This study tests how well MyDay contact lenses work for people over 40 who need reading help. If you wear these lenses and struggle with near vision, this trial may help you find a more comfortable solution.
This trial tests a new treatment called the VIS Opti-K™ System to help people with presbyopia (age-related trouble seeing up close) see better without glasses. It uses a special lens to improve near vision in one eye while keeping distance vision clear.
This trial tests a new light-based treatment to help aging eyes focus better on close objects, which could reduce the need for reading glasses.
This study compares two laser eye surgery approaches for people over 40 who need reading glasses. Both methods use LASIK to reduce or eliminate your need for glasses, but they work differently—one eye may be set for distance and one for close-up (monovision), or both eyes may be adjusted for mixed vision (blended vision).
