Computer Glasses

antireflective largeComputer glasses are specialty eyeglasses made specifically to address the unique visual needs of extended computer and smartphone use. To address these needs, computer glasses are made completely differently, in a number of important ways, from regular eyeglasses and reading glasses. These significant differences are what make computer glasses absolutely essential for maintaining both your short term visual comfort and long term visual health as you work and play in a world increasingly dominated by computers and smartphones.
 
 
To begin explaining the benefits of computer glasses, it is important to point out that computer screens are generally positioned around 20-26 inches from your eyes. This is what eyecare professionals call your “intermediate” zone of vision. Unfortunately, traditional eyeglasses are not made in a way that is conducive to intermediate viewing of the type required by computer work. This often leads to blurred vision, eyestrain and headaches after extended computer use.
 
Computer glasses, on the other hand, are specifically made to emphasize comfortable intermediate viewing, helping your eyes more easily focus on the computer screen with less effort and making computer viewing over an extended period of time noticeably more comfortable.
 
Those who spend extended amounts of time on the computer would also be wise to note another factor that often contributes to computer related discomfort and may even be potentially sight-threatening: blue light. This high-energy light comes from computer screens, televisions and smartphones, and has been known to cause eyestrain, headaches and fatigue. Recent studies also point to growing evidence that blue light exposure has the potential to significantly increase a person's risk of macular degeneration over time.
 
Computer glasses are often equipped with specialty lenses, such as BluTech and Crizal Prevencia, that are meant to reduce or eliminate many of the harmful side effects linked to increased time in front of computers and other electronic devices. This is accomplished by selectively filtering out blue light, which enhances visual comfort and minimizes eyestrain. At the same time, these lenses allow non-harmful light to pass through, allowing for the clearest vision possible.
 
Specialty lens coatings may also be applied to computer glasses. Among the most popular of these specialty coatings is HOYA Recharge. This special lens treatment reflects about 30% of harmful blue light away from the eye. In conjunction with the specialty lenses mentioned above, HOYA Recharge can help significantly increase the amount of blue light filtered or reflected away from the eye, making computer use noticeably more comfortable.
 
Computer glasses are an absolute necessity for maintaining both your short term visual comfort and long term visual health as you work and play in a world increasingly dominated by computers and smart phones.
