Therefore, the possibility of unsuitable lenses purchased without consultation is very high. Sometimes people order lenses without examination and then get disappointed that they don’t fit. Regardless of the fact that they might not even know how to wear them, which an expert might teach them too.

“The details are the so-called patients of electronic stores,” says Lucie Macháčková. “Currently, I mainly work with customers from the online store and many satisfactory results on this I’ve never seen one before in over 10 years of practicing optometry. Buying contact lenses online is totally fine, but the problem is that people decide to buy without consulting their ophthalmologist or ophthalmologist first.

2. Go for regular check-ups

The journey to better vision does not end with the purchase of lenses. Experts advise conducting monitoring examinations twice a year. eyes Originally perfect lenses may not fit after some time.
