Ocular lens pigmentation develops with age, and is critical to help block the blue light rays that can cause macular degeneration. Children, in particular, are susceptible to damage since they have no ocular lens pigment at birth. In addition, anyone with a personal history or family history of macular degeneration is at higher risk and should be protected with blue blocking lenses. Finally, anyone who spends more than three hours per day looking at devices that emit blue light… smartphones, tablets, computer and television screens…. should be protected as well.
Computer 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 an 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 special coatings or lenses that are made specifically to filter harmful blue light so that it does not reach your eyes. This makes extended computer use more comfortable and reduces the risk of developing macular degeneration in the future.
