Your eyes can change even when your contact lenses stay the same. A prescription that once worked well may no longer provide clear vision. Blurry sight, redness, dryness, or discomfort can be signs that your lenses need a review.

An optometrist Tustin residents trust can check your vision, eye health, and lens fit. Regular contact lens exams can help keep your eyes comfortable and your vision clear.

1. Your Vision Is Not as Clear

Your contacts should help you see clearly. If things look blurry, hazy, or out of focus, pay attention. You may notice this when reading signs, using a computer, driving, or looking at things far away. Your vision may also become blurry only at certain times of the day.

A change in your prescription could be one reason. Your contact lens may also not fit your eye properly. A new exam can help find the cause.

2. Your Contacts Feel Uncomfortable

Contact lenses should not constantly bother your eyes. You may feel like something is stuck in your eye. Your lenses may feel dry, scratchy, or irritating. You may also notice burning or stinging.

These signs can have different causes. Dry eyes are common. Spending long hours looking at screens can also reduce how often you blink. This can make contact lenses feel less comfortable. An eye doctor can check your eyes and see if your current lenses are still a good fit.

3. Your Eyes Are Often Red

Red eyes after wearing contacts should not become your normal. Mild irritation can happen. But repeated or strong redness may point to a problem. It can be caused by dryness, irritation, poor lens care, or an eye infection.

If your eye becomes very red or painful, remove your contacts. Do not put them back in until you have been advised that it is safe to do so. Sudden eye pain, sudden vision loss, strong light sensitivity, or other serious symptoms need prompt medical attention.

4. You Cannot Wear Your Contacts as Long

Maybe you used to wear your contacts all day without a problem. Now, you need to take them out after a few hours. That change matters.

Your eyes may be getting drier. Your prescription may have changed. Your lenses may no longer fit as well as they once did. You do not have to simply put up with the discomfort. An eye exam can help identify what has changed.

5. Your Contact Lens Prescription Is Old

Your contact lens prescription can change over time. Even a small change may affect how clearly you see. If you are using an old prescription or have not had your eyes checked recently, schedule an exam.

During a contact lens exam, your eye doctor can check your vision and eye health. They can also assess how the lens sits on your eye.

6. Your Daily Routine Has Changed

Your eyes may have different needs now than they did a few years ago. Perhaps you spend more time on a computer. Maybe you drive more often around Tustin. You may have started playing outdoor sports or working longer hours. These changes can affect your contact lens comfort and vision.

There are different types of contact lenses for different needs. Some are made for astigmatism. Others are designed for people who need help seeing both near and far. Your eye doctor can help determine which type may suit your eyes and lifestyle.

7. Your Contacts Keep Moving

A contact lens should sit properly on your eye. If it moves around when you blink, feels like it is slipping, or seems to shift often, your lens may not fit correctly.

A poor fit can affect both comfort and vision. Your eye doctor can check the fit and take the measurements needed to find a better option.

When Should You Get a New Contact Lens Exam?

If your contacts no longer feel as comfortable as they once did, it may be time for an eye exam. Blurry vision, redness, dryness, and reduced wearing time should not be ignored.
