Artificial tears will lubricate, sooth, promote healing and re-wet the surface of the eyes. It is often used as part of the treatment plan for dry eye syndrome and computer vision syndrome.
Types of Artificial Tears
There are mainly two types: preservatived and non-preservatived. Preservatives can sometimes irritate and cause dryness. Non-preserved tears have less chemicals and can be used as often as needed.
How Often Should I Use Them?
These eye drops work much better if they are used before you eyes feel dry. I recommend using them four times a day for two weeks, then three times a day the next week, then twice a day the next week, etc. At some point, you may notice that your eyes are not as comfortable as the week before. You have now find the frequency you need to use these eye drops to keep you eyes lubricated and comfortable.
You can also try a lubricating ointment which lubricates your eyes better and last longer than drops. It is most commonly used before bed time, as it may blur your vision for 10-15 minutes. Be cautious if your are operating a vehicle or machinery. Please consult your doctor of optometry before starting any artificial tears to ensure that you are using the most suitable one.
