Prioritize UV protection

Besides aesthetics, glass frame material also needs to be emphasized. Frames made of high-quality acetate plastic or Titanium metal provide a light feeling but have high durability, and can withstand physical impacts during strong movements of guys.
Check the color of the glasses
The color of the glasses affects the contrast and color recognition ability of the user. Gray is a popular choice because it retains the most natural landscape color. Brown or amber helps increase contrast, suitable for sports or driving in low light conditions.
Meanwhile, green will help reduce glare and eye strain effectively. Depending on the nature of the job, choosing the right eyewear color will enhance the experience as well as help protect the eyes of men.
