What is astigmatism?

Defects in the spherical curvature of your eye or the eye's lens are known to cause astigmatism. This defect prevents light rays from coming together within the eye and stops you from being able to focus on objects. It causes images to look distorted and blurry.

The severity of your astigmatism will determine the amount of correction that's needed to restore your eyesight and allow you to see things more clearly. Dr. Feiz can take accurate measurements and prescribe a lens that allows you to see things that are close to you, as well as far away.

When should bifocals be considered?

Dr. Feiz often recommends bifocals when you begin to have trouble reading the small print that is within a few inches of your face. As you age, your ability to see objects that are farther away will remain intact, while your capacity to see things up close deteriorates.

Dr. Feiz prescribes bifocals when your “close-up” vision begins to suffer. A smaller, stronger lens is placed into the normal lens of your eyeglasses, allowing you the option of glancing down and looking through the stronger portion if you are having trouble focusing on something that is smaller than normal.

What is a “progressive lens”?

If you're one of Dr. Feiz's patients who wear bifocals or trifocals, you've more than likely seen the lines that divide each focal lens from the main portion. Progressive lenses are often referred to as “no-line” bifocals/trifocals because no line is visible between the different lenses.

Each lens gradually transitions from one to the other providing you with a smooth or “progressive” movement. This reduces the difficulty the eyes have when it comes to focusing as you are trying to look at objects through your eyeglasses. Transitional lenses cause less eyestrain and may reduce the risk of a headache as your eyes adapt to using the different lenses.
