Pros and Cons of Monthly, Bi-weekly and Daily Contact Lenses

At Infinity Eyecare of Denver, we often get asked what the differences are between monthly, bi-weekly and daily disposable contacts. Below we explore the differences between each and the pros and cons.

Monthly Contact Lenses:

Monthly lenses are designed to be worn for one month before being replaced. They are typically worn during the day and removed at night. Monthly contacts require proper cleaning and storage.

Pros:

• Cost-Effective: Monthly lenses may be more cost-effective compared to bi-weekly and daily lenses.
• Less Packaging Waste: Using fewer lenses reduces packaging waste compared to daily disposables.

Cons:

• Maintenance: Requires regular cleaning and proper storage.
• Risk of Deposits: Longer usage time increases the risk of protein and lipid deposits on the lenses. These can lead to blurry vision and infections.
• Potential for Irritation: Extended wear may lead to discomfort or irritation over time. Especially in Colorado with the dry air, many patients experience more dryness and irritation than bi-weekly and daily lenses.

Bi-weekly Contact Lenses:

Bi-weekly lenses are replaced every two weeks. Similar to monthly lenses, they are worn during the day and removed at night. Regular cleaning and storage are necessary.

Pros:

• More Convenient than Monthly: The shorter replacement schedule may be more convenient for some users.
• Less risk for irritation and deposits compared to monthly lenses since they are replaced more frequently.
• More cost-effective than daily lenses

Cons:

• Still Requires Maintenance: While not as frequent as monthly lenses, they still require regular cleaning and storage.
• Risk of Deposits: Similar to monthly lenses, there is a risk of deposits on the lenses, even though the bi-weekly frequency is usually better (with proper hygiene and correct usage) than monthlies, it can still develop.
• They usually are more expensive than monthly lenses.

Daily Contact Lenses:

Pros:

• Convenience: No need for cleaning or storage; simply discard after use.
• Reduced Allergy Risk: Lower risk of allergies or irritations since the lenses are fresh each day.
• The most hygienic: Because you dispose of lenses each day, they are much better for your eyes than monthly or bi-weekly and significantly reduce the chances of eye infections and risk of protein and lipid deposits.
• Less Dry and more comfortable: Many patients find that daily lenses tend to be more moist than monthly and bi-weekly lenses. This is in part to being disposed of every day and a fresh new pair each time, but also, they tend to be thinner than monthly and bi-weekly which tends to be more comfortable.
• Great for Occasional Use: Ideal for occasional wearers or special occasions such as weddings or for certain hobbies like skiing, hiking, swimming, and sports.
• No solutions or contact lenses cases are necessary!

Cons:

• Cost: Daily disposables can be more expensive than monthly or bi-weekly lenses.
• More waste: Each lens is individually packaged and so there is more waste and materials than monthly or bi-weekly.*

Ultimately, the choice between monthly, bi-weekly, and daily contact lenses depends on individual preferences, lifestyle, and the advice of an eye care professional. All types can be healthy if used correctly, but improper care can lead to eye issues. In addition, comfort varies from person to person, and it's essential to find what works best for you. Regular eye check-ups and following the recommended replacement schedule are crucial for maintaining good eye health.
