To improve your vision when you are playing basketball, there are mainly two ways, first is wearing eyeglasses, and the second is wearing eye contacts. However, wearing eyeglasses can be quite inconvenient because they may distract your concentration when you need to hold them back to the nose bridge. In addition, playing basketball can sometimes be fierce and it is frequent that the eyeglasses get broken and even hurting your eyes in some serious conditions. Wearing eye contact lenses, however, does not have this kind of trouble. Therefore, as long as you are not highly nearsighted or farsighted, it is better to wear eye contacts when you are playing basketball.
