You might feel a sandlike grittiness in your eyes that can range from mild to severe. People describe the feeling as a lack of lubrication. That’s exactly what it is. Your body isn't making enough tears, or the chemicals in your tears are out of balance. When this happens, you have dry eye.
Dry eye is a medical diagnosis that at times is not taken seriously, say the American Academy of Ophthalmology (AAO) and the American Optometric Association (AOA).
According to the AAO and the AOA, over 3 million women and over 1 million men suffer from dry eye syndrome. This generally increases with age. Dry eye is not just an annoyance. It can cause inflammation, blurred vision, and even blindness in extreme cases.
Changes in your immune response and falling hormone production as you age can lead to dry eye.
Here are some of the medicines that can cause or worsen dry eye:
Some medicines for overactive bladder
Some antinausea and motion sickness medicines
If you have dry eye symptoms and are on medicines, talk to your healthcare provider to see if changes might help.
Some autoimmune disorders, like rheumatoid arthritis, can cause dry eye.
The first line of defense against dry eye is to limit or avoid things that cause symptoms. That includes dry climates. Humidity levels of about 45% or more are best for your eyes. Other factors include forced air (like from a car vent), dusty settings, smoke, and computer screens set so high that they force your eyes to open wider.
Artificial tears that you can buy over the counter can help. Look for products that are just like your own tears, not eye drops sold for allergies or redness. Ask your eye care provider for product recommendations that will be the best for your condition. Prescription eye drops, punctal plugs, hot compresses, and other medicines and treatments can also help. Talk to your eye care provider about these choices.
