Presbyopia can be corrected with glasses or contact lenses. In some cases, the addition of bifocals to an existing lens prescription is enough. New surgical procedures can also provide solutions for those who do not want to wear glasses or contacts but surgery is a risk and the results can’t be guaranteed. As the ability to focus up close worsens, the prescription needs to be changed and probably more than once.
Looks like the adjustable eyeglass market just got a lot more crowded. That means more choices and better cheaper glasses. Hopefully, it means that I can try on a pair to buy soon!
