Running has become one of the most popular sports in Brazil, leading to a surge in discussions around affordable alternatives for gear among enthusiasts. One of the trending topics is the use of 'construction goggles', which are significantly cheaper than traditional running glasses, yielding a price difference of R$ 150 to R$ 300 for running glasses compared to R$ 20 to R$ 30 for construction variants. Given the significant disparity in price, many runners are questioning the potential equivalence in functionality.

Experts explain that while construction goggles may provide basic protection, they lack essential features required for sports activities, such as certified UV protection and a design that ensures stability and ventilation during movement. These characteristics are crucial for minimizing visual fatigue and protecting the eyes from elements like UV rays, wind, and dust while running outdoors. Utilizing goggles that weren't designed for sporting purposes can not only diminish performance but potentially pose risks to eye health.

In conclusion, while the allure of saving money is strong, the consensus among specialists is clear: investing in proper running glasses is advisable for serious runners. The differences in design and protective features underscore the importance of using equipment tailored to the specific demands of sports activities, highlighting that the initial savings might not justify the potential drawbacks associated with using construction goggles for running.
