Could These Eye Drops Replace Reading Glasses? Here’s What Doctors Want You to Know

How the drops work

Vizz contains aceclidine, while Yuvezzi combines carbachol and brimonidine. Both reduce pupil size, which limits incoming light and can help sharpen near vision, according to Dr. Honkanen. The improvement may not make every reading task comfortable. Starting vision, print size and lighting all affect what a person can see, and reading smaller letters on an eye chart does not guarantee easy reading at home.

Benefits vary over time

Manufacturers say Vizz may work for as long as 10 hours and Yuvezzi for as long as eight. Those maximum durations are not a promise of a full day without glasses.

In a Yuvezzi study cited in the article, 10% of people using the medication met a three-line benchmark after eight hours, compared with 3% of those given placebo drops. The same pupil change that supports close vision can also make dim settings harder to see in; Dr. Bert says adapting may take several days.

Who may be a candidate

Dr. Honkanen says the drops may suit people with healthy eyes, mild to moderate near-vision difficulty and good distance vision, with or without correction. Dr. Bert often sees people from their 40s to mid-50s as potential candidates.

Previous LASIK or cataract surgery does not automatically rule someone out, but Dr. McDonald says the doctor should know the person’s prescription before surgery. People who were very nearsighted may face greater retinal risk, even if their vision is now good without glasses.

Risks, costs and alternatives

Pupil-shrinking medicines have been linked to retinal tears or detachments, so both products’ labels recommend a retinal check before use. New flashes, floaters or any loss of vision call for prompt medical care; blurry vision should also be assessed by an eye care provider, since cataracts or another condition may need attention.

The drops can also affect night driving and other activities in low light. They are generally paid for out of pocket, so Dr. McDonald recommends checking the price and possible savings with a pharmacy before filling a prescription.

Dr. McDonald considers patients’ jobs and hobbies when discussing options, since occasional label-reading differs from hours spent with small print. Dr. Yoo says people can use drops alongside glasses or contacts rather than giving up other vision aids.
