[Clinical Edge] Is It Normal for Your Vision to Become Blurry After Using Diquas Eye Drops?

 If your vision becomes blurry immediately after using Diquas® eye drops, it is usually a temporary and expected effect. In most cases, the blurriness clears within a few minutes as the drops spread evenly across the surface of the eye.

However, if the blurred vision persists or is accompanied by significant pain, redness, or worsening vision, you should contact your eye care professional.

Why Does Diquas Cause Temporary Blurred Vision?

Diquas is prescribed to help improve the tear film in people with dry eye disease.

Like many lubricating or tear-stimulating eye drops, it can briefly alter the optical surface of the eye immediately after instillation. As the medication mixes with your natural tears, your vision may appear hazy for a short time before returning to normal.

This temporary blurring is generally not a sign that the medication is harming your eyes.

Should You Continue Using It?

If the blurriness lasts only a few minutes and then resolves, you can usually continue using the medication exactly as prescribed.

You should seek medical advice if:

• Blurred vision lasts much longer than expected
• Eye pain develops
• Redness becomes severe or progressively worse
• Your vision continues to decline after the drops
• You experience new light sensitivity or other concerning symptoms

These symptoms may indicate a condition unrelated to the medication or an adverse reaction that deserves evaluation.

Can You Drive After Using Diquas?

Because temporary blurred vision is common immediately after instillation, avoid driving or operating machinery until your vision is completely clear.

This is especially important before:

• Night driving
• Highway driving
• Precision work requiring sharp vision

Waiting just a few minutes can improve safety.

Frequently Asked Questions

People often search for this issue using different phrases, including:

• My vision is blurry after Diquas
• Diquas makes my vision cloudy
• Is blurry vision normal after Diquas?
• Should I stop using Diquas?
• Diquas side effects blurry vision
• Vision blurry after dry eye drops

Although the wording varies, these questions usually describe the same temporary phenomenon.

Bottom Line

Temporary blurry vision immediately after using Diquas is common and usually resolves within a few minutes. If the blurriness is prolonged or accompanied by pain, significant redness, or worsening vision, you should be evaluated by an eye care professional rather than assuming it is a normal side effect.

Note for international readers: Diquas® (diquafosol ophthalmic solution) is marketed in several countries, including Japan and South Korea, but is not currently available in some regions such as the United States. If you do not have access to Diquas, similar temporary blurring can also occur with many lubricating or prescription dry eye eye drops.
