When you don't produce enough tear fluid, the contact lens can rub against the cornea. This can cause a tired feeling and red eyes. The quality of your tear fluid is also important. When your eyes produce too much tear fluid, as opposed to insufficient tear fluid, the quality of the tear fluid is not good. The eye sends a signal to the lacrimal gland that more tear fluid is needed, resulting in an abundance of tears. You may recognize this feeling from walks or bike rides. A solution for this is 'artificial tears', better known as eye drops. Eye drops for lenses ensure the hydration and refreshment of dry eyes and ensure the maintenance of sufficient tear fluid. Eye drops can also improve the quality of your own tear fluid. Do you need eye drops? Buy eye drops directly at Weblens! Take a look at our range and order your eye drops online!
