Having Problems Seeing? Tips to Improve Your Vision

I spend most of my time working on my laptop or desktop computer. Although I take precautions to keep my eyes healthy, I still experience unexplained vision problems. After speaking to an optometrist about my eye problems, they suggested that I change the lighting in my home and office. The overhead lighting in my work space was actually too bright for my eyes. I lowered the lighting in my ceiling and placed adjustable lamps on my desk. If I need more light, I simply adjust the lamps over my computer screen. I can now work without damaging my eyes. If you have problems with your eyes and can't figure out why, read my blog. I offer real tips you can use that protect your eyes at work or home. Good luck and thanks for stopping by.

Can You Still Wear Contact Lenses If You Need Bifocals?

Bifocals have been around since their invention by Benjamin Franklin in the 18th century, but it has taken considerably longer for that technology to make the leap to contact lenses. Although individuals suffering from presbyopia, or far-sightedness caused by natural aging, were once unable to wear contact lenses effectively, increasingly complex lens manufacturing methods have made it possible for contacts to adjust your both near and far vision separately. 

Understanding How Bifocal Lenses Work

Bifocals use two different lenses to sharpen your vision over both long and short distances. Typically, the lower half of each combined lens focuses on shorter distances, while the top half is used to focus on far-away objects. Constructing a contact lens that offers the same effect without causing dizziness and nausea is a challenge, but manufacturers have found several ways to accomplish it. The most popular of these solutions are monovision and concentric bifocal lenses.   

Considering Monovision Lenses

Monovision lenses do not correct vision like bifocal glasses do, opting instead to have each contact lens resolve images at different distances. In practice, this means that your dominant eye's contact lens will focus on far objects while your secondary eye prioritizes near objects. This was once the preferred method for patients with presbyopia, but it has some disadvantages when compared to newer contact lenses. For example, you may experience compromised depth perception, which can become a problem while driving, as well as slightly decreased distance perception. 

Choosing Multifocal Lenses

Multifocal lenses are more similar to bifocals in function, relying on multiple lenses combined into one contact lens. They typically work by dedicating a small portion of your visual field to near objects, while the rest resolves objects in the distance. Multifocal lenses can be created using either hard or soft materials, but rigid lenses tend to work better. Because of this, if you have sensitive eyes, monovision lenses may be a better choice. Otherwise, multifocal lenses are generally preferred by optometrists as a more elegant solution to the bifocal problem. 

Deciding Between Concentric or Alternating Image Designs

If you do choose to switch to multifocal contact lenses, you will need to decide between the different lens patterns available on the market today. Alternating image lenses are structured much like bifocals, with distances resolved in the top half of your visual field and nearer objects below. Concentric bifocal lenses, on the other hand, form a sort of bulls-eye pattern, with rings of differing focuses working together to create a clear image in your mind. Your optometrist will be able to show you the difference between each type of lens and offer recommendations based on your eye shape and visual needs, so schedule an appointment today (at a clinic such as Discover  Vision Centers) if you are interested in finally ditching your bifocals for contact lenses.
