Is it okay to wear contact lenses on just one eye?


Doctor, I have one eye with myopia over 100 and the other with hyperopia over 100.
I only wear contact lenses for the myopic eye.
Is this okay? Could the difference in eye pressure cause harm? Should I get contact lenses for the other eye, or am I just overthinking this? Is there really no issue with eye pressure? This question has been bothering me for a long time.
Thank you so much...

Hello: That's fine, but perhaps it's better to wear them only occasionally.
Generally, individuals with around 100 degrees of myopia can see objects clearly within 1 meter, so it's better not to wear them for close-up tasks like writing or reading! Best regards, Dr.

More Info


Wearing contact lenses in only one eye, especially when there is a significant difference in vision correction needs between the two eyes, is a common concern among individuals who have refractive errors such as myopia (nearsightedness) and hyperopia (farsightedness). In your case, with one eye being myopic and the other hyperopic, it is understandable to worry about potential complications, including differences in intraocular pressure (IOP) and overall eye health.

First and foremost, it is generally safe to wear contact lenses in just one eye, provided that the lens is fitted properly and you follow good hygiene practices. However, there are several factors to consider:
1. Visual Comfort and Balance: Wearing a contact lens in only one eye can lead to visual imbalance. This may cause discomfort, headaches, or difficulty with depth perception, especially during activities that require good binocular vision, such as sports or driving. If you find that your vision is significantly affected, it may be worth considering a lens for the other eye as well.

2. Intraocular Pressure (IOP): While wearing a contact lens in one eye does not directly affect IOP, it is essential to monitor your eye health regularly. Significant differences in vision correction can sometimes lead to compensatory changes in how your eyes function, but this is not typically a direct cause for concern regarding IOP. However, if you have a history of eye conditions or concerns about your eye pressure, it would be prudent to consult with an eye care professional.

3. Eye Health: Wearing contact lenses requires proper care to avoid complications such as infections or corneal abrasions. Ensure that you are following the recommended guidelines for lens care, including cleaning and storing them correctly, and replacing them as advised. If you experience any discomfort, redness, or changes in vision, it is crucial to seek medical advice promptly.

4. Consultation with an Eye Care Professional: Given your specific situation, it would be beneficial to consult with an optometrist or ophthalmologist. They can provide a comprehensive eye examination, assess your overall eye health, and discuss the potential benefits of wearing a contact lens in the other eye. They can also evaluate whether you might benefit from a different type of lens, such as a multifocal or monovision lens, which can help address both near and far vision needs.

5. Personal Preference and Lifestyle: Ultimately, the decision to wear a contact lens in one eye should also take into account your lifestyle and personal preferences. If you find that wearing a lens in one eye meets your needs without causing discomfort, it may be acceptable for you. However, if you are experiencing any issues or if your activities require better visual acuity, it may be worth exploring options for the other eye.

In summary, while it is generally safe to wear contact lenses in only one eye, it is essential to consider the implications for visual comfort, eye health, and overall balance. Regular check-ups with an eye care professional will help ensure that your eyes remain healthy and that your vision needs are adequately addressed. If you have any lingering concerns about eye pressure or health, do not hesitate to seek professional advice.
