Seven Ways: Dispensing photochromic lenses

Ensure that the frame you choose is the most suitable option for photochromic lenses. Advise your patient on the importance of eye size and frame style. The larger frames will provide more coverage with more UV protection around the patient’s eyes. A wrap-around style will be more suitable for those with a sporty, active lifestyle. Envision what the final outcome will be. A steeper faceform angle will produce more lens thickness, which could cause issues for moderate to high myopes. Lastly, think of frame materials; lightweight properties and longevity are two important factors to consider depending on the intended usage.

Patients trust you and your recommendations. Educate your patient on how photochromic lenses work. Explain every small detail with phrases like these: ‘When UV rays hit the lens, a chemical reaction occurs turning the lens dark outdoors. The reaction reverses when going inside a building and this takes approximately between two and 10 minutes until the lens goes completely clear again. The speed of reaction slows down with age and a small yellowish residue will start appearing. Newer technology such as Transitions XTRActive and Hoya Sensity Dark react to UV light and visible light. This means that your lenses will go dark behind a windshield making your driving more comfortable by reducing the amount of glare.’ You have now set the right expectations for your patient.
