Eyeglasses can now be obtained in as little as 48 hours without visiting an ophthalmologist, thanks to a new process that involves opticians and online platforms. This method begins with an optician measuring the patient's refraction—the eye's ability to focus light—needed for clear vision. This data is then sent to a platform where a distant ophthalmologist reviews the information and may issue a prescription. While the platforms claim this approach reduces delays, they also clarify that a prescription is not automatically given and that the doctor has the right to refuse or refer the patient to further care. Around 200,000 people in France use this method. However, the main union of ophthalmologists has raised concerns about the potential risks involved. They warn that this method may lead to fraud, particularly related to the French social security system, which could be exploited to obtain branded glasses without proper oversight. More importantly, there is a risk that underlying eye diseases may go undetected. Conditions such as cataracts, retinal issues, keratoconus, diabetes-related complications, and glaucoma can affect vision and may not show symptoms early on. These conditions require thorough medical evaluation and are not necessarily identified through refraction alone. Measuring refraction is often compared to focusing a camera—ensuring the image is clear—but it does not detect whether the camera's sensor is damaged. Similarly, a refraction test alone does not identify potential eye health problems. A comprehensive eye exam involves additional tests, such as examining the front part of the eye, the retina, intraocular pressure, and corneal thickness. These assessments are necessary to detect underlying issues and ensure overall eye health. The National Council of the Medical Order supports the ophthalmologists' concerns, emphasizing the need for caution when using this new method. They stress that while refraction is an important part of vision correction, it is not a substitute for a full medical evaluation by a qualified ophthalmologist. This approach highlights the importance of balancing convenience with proper medical oversight to protect both patient health and the integrity of the healthcare system.
