Switching from glasses to contact lenses? Here are 9 things to know
Contact lenses can offer flexibility and clear vision, but they may not be the right choice for everyone. Here’s what to consider before making the switch.
Glasses have long been a simple and reliable way to correct vision. But contact lenses offer another option that works well for many people. They sit directly on the eye and move with it, which can provide a wider field of vision and more freedom during daily activities.
Still, switching from glasses to contact lenses is a health care decision. They’re not a fit for everyone and they require daily care. Thinking about switching from glasses to contact lenses? Here’s what to know.
1. Not every prescription is the same
Many common vision needs, such as nearsightedness or farsightedness, can be corrected with contact lenses. But some higher or more complex prescriptions may have fewer contact lens options.
During contact fittings, an eye care provider will look at the following to determine the best prescription:
- Vision strength
- Shape and curve of eye matter
- How well the lens sits and moves
For example, a common condition called astigmatism causes an irregularly shaped cornea. Certain types of contact lenses are recommended for people with astigmatism.1
2. Eye health comes first
Healthy eyes are key for safe contact lens use. Conditions like chronic dry eye, frequent eye infections or allergies can make contacts uncomfortable or unsafe.2
Some people notice dryness, redness or irritation when first trying contacts. In many cases, different lens materials or how often they are worn can help. In other cases, glasses may remain the better choice. An eye exam helps identify risks before contact lenses are prescribed.

3. Comfort can vary by lens type
Contact lenses come in many forms. Soft lenses are the most common and often feel comfortable right away. Another type of lens, known as rigid gas permeable lenses, offer sharper vision for certain prescriptions.3
Daily disposable lenses are worn once and thrown away. Monthly or biweekly lenses are cleaned and reused. Comfort can depend on lens material, wear time and how well lenses are cleaned.

4. Lifestyle plays a role
Contacts can be helpful for active lifestyles. Many people prefer them for sports, exercise or outdoor activities where glasses may slip or break.
Work environments also matter. Long hours in front of screens, dry air or dusty settings can make contacts less comfortable. Some people choose to wear contacts only part time and switch between glasses and lenses as needed.
5. Contact lenses require daily care
Unlike glasses, contact lenses touch the eye directly and must be handled with clean hands. Reusable lenses need regular cleaning and proper storage to keep eyes healthy.
It’s important to prioritize contact lens hygiene. Skipping cleaning steps or wearing lenses longer than recommended can raise the risk of eye infections such as microbial keratitis, a serious condition that can lead to vision loss.4
6. A contact lens fitting is different from a routine eye exam
A contact lens fitting usually happens after a routine eye exam. During this visit, the eye care provider checks how the lens fits, how the eye responds and how clearly vision is corrected.
The visit often includes time to practice inserting and removing lenses. Follow-up visits may be needed to adjust the prescription or change lens types. Contact wearers should get an eye exam at least once per year.5
7. It can take time to adjust
Wearing contact lenses often comes with a short adjustment period. During the first few days or weeks, some people notice mild discomfort, dryness or awareness of the lenses. Vision may feel slightly different compared to glasses as the eyes adapt. These changes are usually temporary, especially for first-time wearers.
There also may be some trial and error to find the right fit. Small adjustments to lens type or wear time can improve comfort and safety over time. It’s important to talk to an eye care provider about any ongoing discomfort to rule out issues such as infection.

8. Vision benefits may help cover costs
UnitedHealthcare Vision offers vision benefits that help cover contact lens exams and lenses. Coverage varies by plan and may include allowances for glasses or contacts.
9. Contacts are not all-or-nothing
Switching to contacts does not mean giving up glasses. Many people keep both and use them in different situations. Having glasses as a backup is recommended in case of eye irritation, illness or lost lenses.6 Having an option offers flexibility without relying on one solution all the time.
