Can exposure to certain medications, like antihistamines, affect tear production?
Yes, some medications, including antihistamines, may reduce tear production, leading to dry eyes. Consult with a healthcare professional if you experience eye-related side effects.
How does the eye respond to sudden changes in barometric pressure, such as during weather changes?
The eye can generally adapt to changes in barometric pressure during weather shifts, but individuals with certain eye conditions may experience temporary discomfort.
