The first step towards healthy and problem-free eyes is finding an eye specialist. Most people with impaired vision do not know if they have a weak eyesight until they visit a doctor. Only a specialist is able to conduct a few basic tests to know if you need to take care of your eyes before it is too late. Locating an eye doctor near you will help you to get proper examination and can identify any potential underlying eye issues you may have such as glaucoma or diabetic retinopathy. Any refractive error or cataract can be diagnosed at an early stage and can be treated easily. You are likely to undergo a visual acuity test, diopter test, keratometry and slit lamp test as a comprehensive analysis. Further, your doctor may advise more tests depending on the condition of your eyesight and eye health.
