Properly selected contact lenses should not impede tear circulation, the organic functions of the eye or the oxygen supply to the cornea. To ensure that your eyes will tolerate the lenses, it is important to pick a suitable contact lens solution, preferably one containing lubricating component.
The overall tolerability of contact lenses depends upon the environment. Eyes are more irritable and stressed in dusty, windy conditions. Wearing contact lenses in smoking areas also decreases the wearing comfort.
