Progressive Lenses Versus Bifocals – Pros and Cons

Nearly everyone over the age of 65 will experience a reduced elasticity of the lenses of their eyes — a condition called presbyopia.

Those of us lucky enough to have perfect vision until that age will only require reading glasses to help with up-close vision. However, for the 42 percent of Americans who are nearsighted to begin with, a more complex solution will be necessary, such as bifocals, trifocals, or progressive lenses.

Bifocals: Pros And Cons

Bifocals are just what they sound like: glasses with one area that corrects nearsightedness and another area that corrects farsightedness. The worse presbyopia gets, it can start to affect middle distances too, and trifocals help by adding a middle strip for things like reading a computer screen.

If you’ve ever worn bifocals or trifocals, you know all about the line between the sections of the lenses. These lines can be distracting and create an odd “image jump” effect, and they can also serve as evidence of advancing age to anyone who sees them. Anyone who feels these drawbacks are too great to overlook might be more interested in progressive lenses.

The Science Of Progressive Lenses

Thanks to the wonders of modern technology, progressive lenses do what bifocals and trifocals do but without the distracting lines. The way this works is that the prescription gradually changes along a corridor of power, going from supporting distance vision at the top to close vision at the bottom.

The trade off to make such a complex lens work is that the bottom corners of progressive lenses make things appear blurry. Fortunately, newer technology is helping to minimize this flaw. When we examine patients wishing to buy progressive lenses, we measure pupillary distance so that we can place the corridor of power in the best place.

Getting Used To Progressive Lenses

Any time we change the prescription or frame shape of our glasses, it will take some time to get used to the way things look. This is certainly the case for progressive lenses, especially if it’s your first time wearing them. A few things you can do to adjust more quickly include:

  • moving your head instead of your eyes to see different things
  • making sure the glasses fit properly so that the corridor of power stays in the right place
  • practicing looking at objects at different differences by watching TV and reading a book at the same time
  • not giving up! If you switch back and forth between your progressive lenses and your old bifocals, you’ll reset the clock on your eyes getting used to them!

Glaucoma : Why Early Diagnosis Can Save Your Vision

Human eyesight is an incredibly complex system, and a problem like Glaucoma anywhere along the way can lead to seriously compromised vision.

One such problem is glaucoma, a group of eye conditions that affect millions of people in the US, making it the second most common cause of vision loss and blindness in the country. In most cases, this is the result of damage to the optic nerve from increased pressure in the eye.

Intraocular Pressure: A Delicate Balance

The human eye is filled with fluid — aqueous humor in the front chambers, vitreous humor in the larger rear chamber behind the lens. In a healthy eye, the pressure of this fluid remains within a safe range because the amount of aqueous humor being produced is equal to the amount flowing out through the pupil. In an eye with glaucoma, this drainage system does not work the way it should.

Common Risk Factors & Symptoms 

While everyone has some risk of developing glaucoma, certain factors can make it more likely. Glaucoma is far more common in people over 60, particularly minorities. Also, people of Asian descent are at greater risk of angle-closure glaucoma. Glaucoma sometimes offers no symptoms until it has done damage and that’s why it’s so important to get a yearly comprehensive eye exam. Also, age and hereditary can increase risk along with high blood pressure, heart disease, diabetes, or sickle cell anemia.

A major risk factor for glaucoma is heredity. Someone with a sibling who has glaucoma is ten times more likely to develop it than someone who doesn’t. Other risk factors include eye injury and steroid use.

Why An Early Glaucoma Diagnosis Matters

Vision loss from glaucoma is irreversible and there is currently no cure for the disease, but medication and/or surgery can halt its progress as long as we diagnosed it in time. The key to early diagnosis is regular eye exams, especially for those with a high risk of developing the condition. Make sure you’re familiar with your family’s eye health history, and don’t forget to keep us in the loop!
