When you first visit Capital Eye, your Canberra optometrist, we will ask you to bring a list of medications (both oral and topical eye drops) that you’re currently taking. We ask this because certain medications affect your eyesight and eye health. During history-taking, there will be a few questions we ask about your general health. This allows us to evaluate your risk your eye is at for any potential sight-threatening ocular diseases. This week, we will mention a few common types of medication that you might be taking and what affects it has on your overall eye health and vision.
Dry eyes is a complex ocular surface disease which is caused by reduced tear film quality. Your eyes need to be adequately lubricated to ensure it is free from debris, ocular irritation and other foreign bodies. The tear production is quite a delicate process, and it involves the functions of several glands located around your eyelids. Here are some medications that you are taking which could make your dry eye symptoms worse;
- Over the counter contraceptive pills
