Understanding Progressive Lenses

Choosing the right lens for your glasses is a lot easier when you know a thing or two about your options. Progressive lenses are our specialty at Doig Optometry, so it’s only right that we get you acquainted with how this particular lens works and why it might be right for you.

The Basics

Like other corrective lens types, progressive lenses are designed to correct refractive errors that disrupt the eye’s ability to focus light. One of the most important factors in compensating for these issues is lens power. Single vision prescriptions offer a uniform lens power throughout the lens, and bifocal or trifocal lenses offer multiple lens powers that are sharply divided from one another. Progressives, however, provide a continuous range of lens power that increases gradually from the minimum power of your prescription at the top of the lens to maximum power at the bottom, bringing close objects sharply into focus.

Correcting Presbyopia

Most people experience one or more refraction errors, such as nearsightedness, farsightedness, astigmatism, or presbyopia. For those above the age of 35, presbyopia is particularly common and is a natural result of the eye aging. Over time, the lens of the eye loses elasticity and cannot properly refract incoming light, focusing it behind the retina rather than onto it. This results in difficulty focusing on near objects as well as eye strain or headaches. Progressive lenses correct this issue in a way that mimics the eye’s natural accomodation to distance, and they’re particularly handy if you experience presbyopia in addition to other errors.

Progressive Lens Sunglasses

The central reason why so many people choose progressive lenses is their convenience and versatility. They do what bifocals and trifocals do, only more smoothly and dynamically. Not only this, but when you need sunglasses made from your prescription, you’ll be able to stay active and enjoy the outdoors with a great-looking pair that is free of unsightly lines. No one should be unfairly limited by stylistic or lifestyle factors when choosing their glasses, and the same should go for sunglasses as well. Whether you’re indoors or in the sun, if you want to see clearly and maintain a youthful and modern look, progressive lenses are an excellent solution.
