Smartfocus glasses are designed to enhance vision and improve focus. However, like any product, they may come with side effects for some users. It's essential to understand these potential issues before making a purchase.

Common side effects reported by users include eye strain and discomfort, particularly when wearing the glasses for extended periods. Some individuals may also experience headaches as their eyes adjust to the new lenses. It's advisable to take regular breaks while using Smartfocus glasses.

In rare cases, users have noted an increase in sensitivity to light. If you experience any severe discomfort or prolonged side effects, consulting an eye care professional is recommended to ensure your vision health is not compromised.
