Chew Eyewear is an optometrist at #01-155 Bishan North Shopping Mall on Bishan Street 22, with a 4.9 Google rating; details are on its Facebook page. A good optometrist does more than read a letter chart: a proper eye examination checks the health of the eyes as well as the prescription, picking up early signs of conditions such as glaucoma. In Singapore, where childhood myopia rates are among the highest in the world, regular checks for school-aged children matter especially, as prescriptions can shift quickly during the growing years. Regulars bring their current glasses, allow time for a careful refraction rather than a rushed one, and ask which lens choices actually suit how they use their eyes day to day. For Bishan residents, a highly rated optometrist in the neighbourhood mall makes keeping up with eye checks a simple errand.
