Choosing your frames is just the start of the journey in purchasing your glasses. There are a number of different lens options available with a variety of features to suit your lifestyle needs.
Below we will discuss the different lens coating options in a bit more detail.
This coating increases the lens durability. Anti-scratch is when the front and back surface of the lenses are treated with a clear, scratch resistant coating. Most lenses are usually made out of polycarbonate or trivex, which come with the anti-scratch as standard. Although the anti-scratch does help with scratches it isn’t completely scratch proof so it is still advised to take good care of the lenses.
This is the most common lens coating people go for. Sometimes this is referred to as “AR coating” or “anti-glare” coating. The anti-reflection coating is applied to the front and back surface of the lens; this reduces the amount of reflections from each surface. The main benefit of this is that allows light to pass through your lenses without the distraction of reflections. This is particularly useful for people that use computer screens and also for driving, especially at night.
This coating allows your lenses to turn dark in the sun. They can sometimes be referred to as “transition” or “reaction” lenses. The main benefit of photochromic lenses is that it allows you to go outdoors on a sunny day without the need of carrying a separate pair of sunglasses. They also keep the eyes protected from the suns UV rays, which is useful to slow down the progression of cataracts and other eye conditions.
The main limitations of photochromic lenses is that they are by triggered UV light which means they stay clear in the car.
