Bifocals, Astigmatism, and Clear VisionAlaa Al Aqrabawi
As you know, our blogs are here to entertain you, but more importantly, they are here to teach you about your eyes. While “what’s the definition of an astigmatism?” may never be a question you find yourself asking on a daily basis, it’s a good idea to have a basic understanding of your eyes. After all, they’re the things that guide you through life.
Come join us on our educational journey. It will be filled with fun times and eye care knowledge.
Let us guess. When you hear bifocals you think of Ben Franklin and your grandparents, right? But what if we told you they are far more common and exciting that you really think?
Any multifocal lens contains two or more lens powers that are positioned according to a person’s vision needs. So, bifocals are exactly that: they have two different lens powers. Typically, the top portion of the lens helps people see far away, while the bottom half of the lens is a different power that can help improve vision when things are close.
Bifocals are typically associated with people who are over 40 because that’s the age that most people notice symptoms of presbyopia. Presbyopia is when someone naturally loses the ability to see things that are close to them clearly. So next time you catch yourself holding your menu or newspaper an arm’s length away, it might be time to ask us about bifocals.
And if you are worried about a harsh line with multifocal lenses, don’t be! A progressive lens gradually changes its lens power as it goes from the top to the bottom of the lens without any chunky transitions between.
Next up, astigmatism.
Astigmatism is a common vision condition that occur when the cornea, which is the clear cover on the eye, or the curvature of the eye is shaped irregularly. The shape prevents light from properly reaching the retina, which is the light sensitive surface located at the back of the eye. And that makes vision blurry at a distance.
Astigmatism can be hereditary and present at birth, so there aren’t many ways to prevent it. However, scheduling a comprehensive eye exam is a great place to start. If necessary, we can even prescribe lens or contacts to fix the astigmatism and alter the way light reaches your eye.
Okay, ready for the fun part? A lot of people think that people with astigmatism can’t have progressive lenses, but that’s not true! If you have trouble seeing up close and far away, bifocals can help you out, even if you have an astigmatism. So don’t doubt your eyewear possibilities! Schedule an appointment with us and let us help you see clearly, no matter what the distance is.
Your eyes do a lot for you. They even helped you read this blog. Take your self-care routine one step further and treat your eyes to a pair of BluTech lenses, sunglasses and a comprehensive eye exam. We can’t wait to see you soon.
