Prescription sunglasses are so convenient that you often forget you are wearing them!
Polarised lenses can improve clarity and reduce eye strain on sunny days by reducing glare and light from the sun. This can improve your vision and safety. When you’re wearing polarised lenses, things will look a bit darker but much clearer and easier to see. They are great for driving and when you’re around the water. However, they make it difficult to see images on LCD such as car dashboards, ATMs, cell phones and some watches.
These are special lenses for sunglasses that change tint precisely when needed. Photochromic lenses react quickly to every situation, sunlight or shade, indoors or outdoors. They are virtually clear indoors and can rapidly change to a stylish tint outdoors to give protection against harmful glare. They provide 100% protection from UVA and UVB radiation. They are available in a choice of brown, green or grey tints. Made from lightweight plastic, they are much lighter than glass lenses. They are really convenient when going in and outdoors to save you having to swap spectacles with sunglasses. However, they do not work as well inside a car due to the car windows absorbing the UV rays which activate the lenses.
