Quality of life with single-vision vs progressive glasses
Part of Eyes & vision clinical trials.
This study compares how people with presbyopia (age-related blurry near vision) feel about their quality of life when wearing single-vision glasses versus progressive lenses. It aims to see which type of glasses helps them see better and feel more satisfied.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 40 and 70 years old.
- You need glasses for distance, and your prescription is within a certain range (not too strong).
- You have trouble seeing close up (like reading) even with your distance glasses, but a stronger reading lens helps.
- You have not used reading glasses or progressive lenses in the past 6 months.
- You can answer a questionnaire and give written consent.

This trial compares two types of progressive glasses to see which works better for seeing at arm's length and up close. It is for people with presbyopia who have relatively mild vision problems.
This study tests two types of progressive lenses (which help you see at different distances) to see how they affect your field of vision. It may help you find glasses that work better for daily tasks like reading and using a computer.
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 study tests a glasses-free 3D training program to see if it can improve both vision and thinking skills in people with presbyopia (age-related difficulty focusing on close objects). If you qualify, you may receive this non-invasive training at no cost.
This study tests a new light-based treatment for presbyopia (age-related trouble focusing on close objects) and near vision correction. It may help reduce the need for reading glasses by reshaping the cornea, the clear front part of the eye.
This study tests whether special reading glasses can improve close-up vision and reduce eye strain in textile workers over 40. If you have trouble seeing close work and often get tired eyes, this might help.
