Astigmatism is a common vision condition that can make objects look blurry, stretched, shadowed, or distorted. This patient-friendly guide explains what astigmatism is, why it can cause night glare, how glasses and toric contacts help, and which common myths patients should stop worrying about.

Photochromic lenses are a convenient lens upgrade that automatically darkens outdoors and clears indoors. They offer UV protection and comfort, but they may not fully replace polarized sunglasses, especially for driving.

MiSight 1 day is an FDA-approved soft contact lens designed to both correct childhood myopia and slow its progression. This clinical guide walks optometrists through patient selection, baseline testing, lens fitting, axial-length monitoring, follow-up intervals, troubleshooting, and treatment-response decisions—from the first consultation through long-term management.

Modern myopia management requires more than monitoring a child’s spectacle prescription. This clinician-focused guide reviews how optometrists can interpret axial elongation, establish treatment targets, fit MiSight contact lenses, select low-dose atropine concentrations, evaluate orthokeratology topography, identify inadequate treatment response, consider combination therapy, and establish appropriate follow-up intervals.

Myopia, or nearsightedness, often becomes stronger as children grow. Modern myopia-control treatments are designed not only to help children see clearly today, but also to slow the eye growth that causes their prescription to worsen over time.

Amblyopia, often called lazy eye, happens when the brain does not fully learn to use one eye clearly during childhood. Early treatment with glasses, patching, drops, or binocular vision therapy can make a major difference in long-term vision.

Your eye exam after 40 is about more than updating your glasses. It helps detect early signs of presbyopia, glaucoma, dry eye, cataracts, retinal disease, and health conditions like diabetes or high blood pressure.

A changing glasses prescription does not always mean something is wrong with your eyes. Age, dry eye, blood sugar changes, cataracts, screen use, and normal refractive shifts can all affect how clearly you see. Here’s why your prescription may change even when your eye health is normal.
