Some advantages of transition lenses include reduction of eye strain, reduced light sensitivity, vivid colors and easier customization. Some disadvantages include low performance in cars, non-polarized lenses and unsuitability for outdoor photos.
Other advantages of transition lenses include availability of different types of tints to suit the preferences of the wearer, no need to purchase separate prescription eyeglasses, and suitability for children. The eyeglasses are made of materials that are compatible with bifocal, single vision and progressive lenses.
Transition lenses are unsuitable for outdoor photos because their lenses darken immediately when exposed to bright light. This eventually hides the eyes from being captured clearly in the picture. However, this feature may be an advantage for people who prefer hiding their eyes behind sunglasses when taking pictures.
The lenses are also unsuitable for use in cars because the windshield blocks the UV rays that are needed to activate the darkening mechanism of the transition lenses. This should not be a problem for users who own convertible cars due to the availability of natural light.
The price of transition eyeglasses varies depending on design, materials and brand. On Amazon.com and eBay, most transition lenses cost between $30 and $100, as of 2015.
