When you’re sitting at a computer, the screen is usually positioned farther away from your eyes, compared to how closely you would hold a book. This puts the computer screen in the intermediate zone where reading glasses are not as effective. For those who wear trifocals, the narrow strip that is used for intermediate vision may not be large enough for comfortable viewing for long periods.
Computer glasses perform very similarly to reading glasses, but they are designed specifically for intermediate vision with magnification power that is determined based on how close you typically sit to the computer screen.
If the distance isn’t an issue for you, you may be experiencing problems sure to the bright light from the screen. Computer glasses can also help alleviate the stress on your eyes from the screen’s light. These types of glasses can be tinted or customized with special coatings, such as photochromic lenses to protect your eyes from the blue light of the screen or anti-reflective coating to protect your eye s from glare. You can even get lenses in a different color that can help better filter the light.
With computer glasses, you can minimize or eliminate the effects that digital eye strain can have on your vision. Before you purchase computer eyeglasses, be sure to schedule an eye exam to ensure your prescription is up to date and to have your eye health evaluated.
