Half full or half empty with Transitions®

June 6, 2016 |  This is a very common question that we field daily "Should I get Transitions® lenses"... Hopefully this post will help you decide...  Transitions® lenses are plastic eyeglass lenses that become dark with UV light exposure.  (I am making this clarification because it is common to hear folks confusing Transitions® lenses with progressive lenses which change power to help us over 40 read  i.e. bifocals)
Transitions® are wonderful lenses that help with glare and provide UV protection.  They have a couple of limitations that you should be aware of... 1) they do not go full dark in a vehicle.   Because they rely on UV light to go dark and the windshields of your car block a great deal of UV light... They only go about half dark.   If you are someone that does not rely on sunglasses now... they are great.   However, if you find that you need sunglasses or clip-ons regularly... these lenses will likely not be dark enough for you when driving.   2) the darkening and lightening of the lenses is not instant and is effected by temperature.   Summer heat and winter cold will definitely effect the change times.  I do encourage most interested patients to try Transitions® as they have a risk-free trial period.     Hope that helps!  Dr.j.
