Common Reasons Why People Wear Only One Contact Lens

Individual reasons surely differ. Financial issues might also lead to the decision of wearing only one contact lens while others are using it for vision correction purposes because of a method called Monovision.

Monovision Explanation

The condition that makes it hard to see up close is called Monovision and it is common in people over 40 years of age. Monovision contact lens approach is to help with distance vision by wearing it in the dominant eye while the other eye helps with near vision.

However, the trick about true monovision is that you will wear contact lenses in both eyes but each lens will have a different correcting task. This is usually done under your doctor’s advice and monitoring for safety and getting the desired outcome.

Possible Effect of Wearing Only One Contact lens

When you use only one lens, there will be an imbalance between your eyes because your brain gets two different images, which can lead to headaches, blurry vision, eye strain, and difficulty seeing in 3D.

You don’t want to wear one contact and cause all this hurt to your eyes, right? Your two eyes work as a pair; don’t confuse them with one eye contact lens and make your struggle to create one clear picture.

Depth Perception and Distance Vision Problems

Your depth perception begins to suffer when you wear only one lens. Over time, you might struggle to tell objects’ distance, which is very dangerous for driving, walking on uneven ground, and sports purposes.

The dominant eye may focus fine while the other stays blurry, making it harder to read signposts or see objects clearly from a far distance. The damage is scary, isn’t it?

Heavy Workload on One Eye

The eye with the lens does most of the work if you keep up the act for a long time, making one eye lazy and weaker. This condition is called eye dominance overload, which may cause the vision in the eye without a lens to get worse.

Also, your brain will start ignoring the blurry images from the other eye, which can result in vision loss if left untreated. With this, I know you are already convinced that wearing a single contact lens for long periods is a no.

Another thing to note is that if your lens is too old or is not meant for your prescription, you may damage the eye you are wearing it on. Don’t just put random contact lenses in your eyes.

Things To Do If You Lost A Lens

Losing a lens can be beyond your control but don’t settle for wearing just one because of that. You can wear glasses as a temporary alternative because they help maintain balance and depth perception, giving equal correction to both eyes when working on a computer or driving. Reading glasses should be used if you want to read for a long time.

Also, contact your ophthalmologist for vision correction advice. If you have to wear one contact lens, don’t wear it throughout the day, and avoid driving or doing anything risky while you put it on. It might be fine but it is never safe.

Importance of Eye Doctor

Before you wear or change your contact lens, consult your eye doctor so they can check your vision. Get the prescription for the right correction for monovision and be informed about the risks. Seeing a doctor helps avoid problems and keeps your eyes safe.

Conclusion

Always be intentional about your vision health. Just because a single lens seems good doesn’t mean it is safe. Make sure your eyes and brain are working in sync without stress. So, unless your eye doctor says otherwise, don’t do anything on your own.
