As people often assume that professional athletes have perfect vision, it may be surprising to discover that some do in fact wear glasses or contacts while training and competing.

One well-known example is basketball player LeBron James, who has been spotted wearing glasses both on and off the court. James has been diagnosed with both far-sightedness and near-sightedness and appeared in a commercial for Nike eyewear in 2015.

Another high-profile athlete who wears glasses is footballer Neymar Jr., who is rumored to have worn corrective lenses since childhood due to near-sightedness.

Tennis player Novak Djokovic is another example, having worn glasses during interviews and public appearances. In 2012, he underwent surgery to correct his vision, but still wears glasses occasionally.

Glasses are not limited to just these few famous athletes. In fact, many professional athletes require glasses or contacts for vision correction while they train and compete.

Overall, while glasses and contacts are often stigmatized in the world of sports, it is clear that they do not hinder an athlete's performance. With proper vision correction, these athletes have achieved great success in their respective sports.
