If the BC is not the right fit for an individual's eye shape and size, it can lead to discomfort, poor vision, and potential damage to the eye. It is crucial to have the correct BC measurement to ensure the contact lenses are comfortable and provide optimal vision correction. **

It's best to consult with your eye care provider to determine which option is most suitable for your needs. **

Polarized lenses in sunglasses are designed to reduce glare from surfaces such as water, snow, and roads. They contain a special filter that blocks intense reflected light, allowing only vertical light to pass through.
