MIDO, held in Milan every January/February at Fiera Milano, is the world’s largest optical trade show: 1,200+ exhibitors from 50 countries, 42,000 visitors from 160 nations in 2026. This guide covers the show floor, frame trends, the MIDO Awards, and an honest decision framework for North American ECPs weighing the transatlantic trip.

Yes, you can have both conditions in the same eye. Myopia (nearsightedness) blurs distant objects because the eye is too long or the cornea curves too steeply. Astigmatism blurs or distorts vision at all distances because the cornea is irregularly shaped, like a football rather than a sphere. When both occur together, it is calledContinue reading “Myopia and Astigmatism: Differences, Symptoms, and Correction”

Progressive lenses correct distance, intermediate, and near vision in a single lens by distributing power across a continuous gradient from top to bottom. No visible lines, no image jump. They are the standard first choice for presbyopic patients across most clinical practices, and when fitted correctly with accurate measurements, the vast majority of patients adaptContinue reading “Progressive Lenses: Types, Fitting, and How They Work”

Three categories of AI tools are production-ready for optical practices today: AI-designed progressive lenses from major manufacturers, digital PD measurement via smartphone cameras, and autonomous diabetic retinopathy screening. Everything else, including AI frame recommendation engines and AI-driven practice management, ranges from early-stage to marketing hype. This guide breaks down each category by maturity, clinical evidence,Continue reading “AI in Optical Practices: What Actually Works in 2026”

Pantoscopic tilt is the angle between the plane of a spectacle lens and the vertical plane when the frame is worn in the patient’s habitual head position. Most adults wear frames at 8-12 degrees of tilt. This angle changes effective lens power, induces unwanted cylinder, and shifts the optical center position relative to the pupil.Continue reading “Pantoscopic Tilt: How Frame Angle Changes Lens Power, Progressive Fitting, and When to Compensate”

Yes, you can fit and sell prescription eyeglasses remotely. You need to solve five problems: collecting a verified prescription, capturing accurate remote measurements, guiding frame and lens selection at a distance, executing clean lab orders, and supporting the patient after delivery. This playbook walks through each step with the operational detail you need to launchContinue reading “Remote Eyewear Fitting Playbook for Optical Shops”

The average optical shop remakes 15% of lens orders. Here is what each remake actually costs and how to cut your rate to under 5%.

Children’s pupillary distance ranges from approximately 50 mm at age 5 to 60 mm at age 15, based on normative data from MacLachlan & Howland’s study of 1,311 subjects aged 1 month to 19 years. Growth is fastest between ages 5 and 8 (roughly 1.0-1.3 mm per year) and slows to under 0.5 mm perContinue reading “Measuring PD in Children: Age Ranges and Techniques”

Vision Expo 2026 ran March 11 to 14 at the Orange County Convention Center in Orlando. This is the first unified annual show, replacing the former East and West split. More than 350 exhibitors, 220+ CE hours, and attendees from over 100 countries. Here is what to know before you go.

Blue light glasses do not reduce digital eye strain. The American Academy of Ophthalmology states that “there is no scientific evidence that blue light from digital devices causes damage to your eye” and does not recommend any special blue light-blocking eyewear for computer use. A 2023 Cochrane review of 17 randomized trials confirmed these lensesContinue reading “Blue Light Glasses: What the Science Actually Says”
