One should see an ophthalmologist for routine eye exams, especially if one experiences any changes in vision (including vision loss), eye pain, redness, or sudden vision disturbances.

Those with a family history of eye diseases like glaucoma or have conditions such as diabetes should also seek regular evaluations from a Singapore eye doctor to monitor their eye health.

Lastly, if there's a need for specialized eye care, such as cataract surgery or vision correction surgeries like LASIK, consulting an ophthalmologist in Singapore is key to obtaining proper diagnosis and treatment.
