Why Not All Photochromic Lenses Are the Same

Photochromic lenses have become a common recommendation, but there are real differences in how each product performs. These differences matter because patients rely on consistent clarity and comfort when they move between bright and shaded areas.

The first point to consider is transition speed. Some photochromic lenses take longer to darken outdoors. Others lighten more slowly when the patient goes inside. These delays affect comfort, especially for people who shift environments throughout the day.

Another factor is the darkness of the lens. While there are many photochromic lenses available in the market, poor quality photochromics have a very mild coloring, offering little protection despite a hefty price tag. The darkness of the photochromic is especially important due to our extremely warm climate in the Philippines.

Base material also plays a role. Many lenses darken unevenly if the material does not match the photochromic compound well. This affects clarity and sometimes colour balance. When a lens responds evenly across the surface, patients enjoy smoother transitions and less eye strain.

Coating stability is important as well. Weak coatings can compromise performance and shorten the usable life of the lens. A strong coating ensures the lens continues to respond the way it should even after repeated cleaning or extended wear.

When you understand these differences, you can guide patients toward lenses that suit their needs rather than treating all photochromic products as interchangeable. This leads to fewer complaints and stronger confidence in your recommendations.
