There are many lens materials, designs, and options when it comes to optical lenses. In order to make sure you get the most out of your eyewear, our opticians can help you select the option that works best for not only your type of prescription, but also your daily visual needs. For example, a patient that spends 8+ hours on a computer screen may need a different lens design than one that drives for a living. There are also lens options ideal for those who may have a more active lifestyle, play sports, or work outdoors. We will help you find the ideal fit when it comes to your eyeglass lenses.
Blue Light Filter
Visible light falls on a spectrum. Think of a rainbow – the human eye sees an array of colors from red to blue. Light that is invisible to the human eye falls on either side of the visible light spectrum, from infrared to ultraviolet rays.
Red light has a longer wavelength and emits less energy, and blue light has a shorter wavelength which emits more energy. Blue light is all around us – it comes from all light sources, even the sun. Blue light is a concern when it comes to digital devices due to the close proximity to our eyes for extended periods of time. As optometrists, our concern is that damage from the exposure to high energy blue light over a period of time could increase the occurrence of macular degeneration, along with cataract formation.
Fortunately, we have the ability to protect our eyes from blue light rays with "blue light filter" coatings that can be used on prescription and even non-prescription lenses. Traditionally people may think of a blue blocker- in which the lenses take on a bright yellow tint. Ophthalmic grade lens coatings are very advanced and have almost no color to them.
