Understanding Blurry Vision

If you’re unable to see clearly, far, near, or both, then you are suffering from blurry vision. Blurry vision is an extremely common symptom but may have numerous different causes or multiple causes contributing to it. Some causes may be easy to treat, and others may be chronic and progressive despite available treatments.

The Underlying Causes of Blurry Vision

Age-Related Macular Degeneration

Macular degeneration is a common cause of blurred central vision among older adults. In addition to blurry vision, straight lines may appear wavy, you may see a blind spot in the center of your vision, and you may have difficulty recognizing faces. 


When you have glaucoma, your optic nerve thins over time, and peripheral vision is lost. The condition is more common among older adults and is treated by lowering the pressure in the eye. This can be achieved with eye drops, minor procedures, or surgery. 


Cataracts form when your eye lens becomes clouded. Many of our patients liken it to trying to see through a frosted window. This condition can make it difficult to read and drive at night. You can develop cataracts in one or both eyes, and symptoms can include blurry vision, light sensitivity, seeing halos around lights, double vision, and more. When cataracts first develop, brighter lights and eyeglasses or contact lenses are usually sufficient to help you see better. Once your cloudy vision impacts your ability to drive and engage in your usual activities, cataract surgery may be necessary. 

    Dry Eye Syndrome

    Dry eye syndrome is another very common cause of blurred vision. If your eyesight improves when you blink, it’s a sign that dry eye syndrome may be to blame.

    You may experience itching, pain, redness, and irritation as well. In this case, your blurred vision and dryness can be treated with artificial tears, good eyelid hygiene, lifestyle adjustments and prescription interventions.

    Refractive Errors

    Refractive errors are one of the most common causes of blurry vision and, luckily, are the easiest to treat. Treatment includes daily use of glasses or contact lenses or a one-time procedure. Refractive errors happen when your eyes can’t focus on images correctly due to them being either too long, short, or not perfectly round. You may have heard of the different types of refractive error below: 

    • Farsightedness (Hyperopia) - can’t see up close
    • Nearsightedness (Myopia) - can’t see distance
    • Astigmatism - objects are distorted
    • Age-related Farsightedness (Presbyopia) - reading problems occurring with age

    How is Blurry Vision Treated?

    Eyeglasses and Contact Lenses

    If your blurry vision is caused by refractive issues, the first treatment will likely be eyeglasses or contact lenses. These solutions work by focusing light so you can see objects clearly. 

    Eye Surgery

    Since we have the ability to permanently treat the majority of patients with refractive error, we hope to make procedures the default method of treatment in our community. We consider glasses and contacts to be prosthetic devices that are very useful but an unnecessary burden for many. Here’s a closer look at the most common eye procedure we perform at Beach Cities Laser Vision in Torrance:


    RLE replaces your dysfunctional lens with a new, artificial lens. This procedure corrects the refractive error and removes/prevents the worsening of cataracts.

    PRK is performed to correct common refractive errors. It has great results but has a longer healing time than other procedures.

    LASIK is probably the most well-known laser eye surgery. During this procedure, a laser superficially changes the shape of your cornea to correct most refractive errors.

    EVO ICL is a biocompatible lens implant to correct nearsightedness and astigmatism. This procedure is especially good for patients who may have been told they weren’t candidates before.

    SMILE, a type of LASIK that can correct astigmatism and nearsightedness,takes 5 minutes for each eye, and 99% of patients can return to all their activities the next day.
