Eye Spectrum is an optometry practice at 5 Upper Boon Keng Road in Kallang, Singapore, holding a 5.0 Google rating; its online presence is a Facebook page rather than a full website. A good optometrist does far more than sell glasses: a proper eye exam checks the retina, optic nerve and eye pressure, and can pick up early signs of glaucoma, diabetes and high blood pressure before you notice any symptoms. That matters in Singapore, where myopia rates are among the highest in the world and children's prescriptions can shift quickly — yearly checks for school-age kids catch changes early and open up more options for slowing progression. Even adults with steady vision do well to have an exam every year or two. Tucked into a block on Upper Boon Keng Road, Eye Spectrum is well placed for Kallang residents who want that kind of ongoing care close to home.
