Prevencia No-Glare Lenses

Solutions for CVS

computer glasses in NYCMany people notice vision problems such as eye strain or blurriness, when they spend a long time on the computer, smart phone or tablet. This discomfort is a condition known as Computer Vision Syndrome and comes from rays or light emitted from the screen you are using, the distance you sit at and other factors.

The rays or light coming from the screen are called “Blue light”. Dr. Patel explains, “Blue light comes from computer screens, modern televisions and smart phones. It has been shown to cause eyestrain, headaches and fatigue. Additionally, studies show that blue light exposure can significantly increase a person’s risk of macular degeneration over time.”

Fortunately, our Manhattan optometrists have a number of solutions to this problem:

Computer Glasses

Computer glasses are made specifically to address the unique needs of those who are on the computer or other electronic devices for extended periods of time each day. The glasses can be worn on top of regular prescription frames or instead of them. They usually have a yellow tint.

A benefit of computer glasses is that they can be made to work with the distance you sit from the computer. Usually a computer screen is positioned about 20-26 inches from your eyes. Traditional eyeglasses are not made for this distance and for people who use regular glasses this can result in headaches and other problems.

Specialty Lenses

Computer glasses can also be made to filter or limit your exposure to blue light. Specialty lenses, such as BluTech and Crizal Prevencia, are made to reduce or filter 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.

At Manhattan Vision, we often prescribe Prevencia lenses for a number of reasons:
1. They reduce blue light exposure
2. They provide coverage against harmful UV rays
3. The lense is clear unlike most blue light reducing lenses which are yellow.

Specialty lens coatings may also be applied to computer glasses. One of the most popular coatings at our midtown Manhattan office is the 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.

No matter which option you and your eye doctor decide to go with, computer glasses are an essential part of our digital world. For more information about how computer glasses can help you, speak to your Manhattan Vision Associates optometrist, today.
