Why You Need an Eye Exam Even If You Have 20/20 Vision

Book Appointment

If you’re lucky enough to have perfect, or 20/20, vision, don’t dismiss the importance of a routine eye exam. Though you may not need eyeglasses, a visit with an experienced optometrist, like Dr. Lau or Dr. Farson, should be a vital part of your preventive health care plan.

Windows to the soul

An in-depth eye examination goes beyond evaluating your eyesight. In fact, the health of your eyes can say a lot about how the rest of your body is working.

A number of underlying health conditions can directly impact your eyes. Conditions, like high blood pressure and diabetes, can cause abnormalities in the blood vessels of your eyes, which an eye care provider can often detect during an eye exam.

Eye-specific disease detection

In addition to identifying underlying medical problems, a routine eye exam can ensure diseases of the eye are caught as early as possible. Quick identification of eye disease can increase your chances for successful treatment.

During the exam, Dr. Lau or Dr. Farson will check your eyes for early signs of conditions like:

  • Glaucoma: a condition that damages the optic nerve and reduces your field of vision
  • Blepharitis: an inflammation of the upper or lower eyelid
  • Cataracts: an age-related clouding of the lens in your eye
  • Detached retina: a serious, emergency condition in which the retina pulls away from the blood vessels that provide nutrients and oxygen
  • Macular degeneration: the chronic deterioration of the central part of the retina, which can result in blindness

Your exam can also involve specific screenings for other hereditary conditions that may have been passed on to you.

Frequency of visits

Even without known vision problems, you should plan to schedule routine eye visits at Mission Viejo Ophthalmology.  Dr. Farson and Dr. Lau recommend annual visits to protect your overall eye health and stay abreast of any changes occurring with your eyes or vision.  

If you wear glasses or contact lenses, you’ll also need annual visits for routine monitoring of your eye health and necessary prescription changes. Any sign of disease or other health concerns that can interfere with your eyes may also require annual exams.

Stay on top of vision changes

Because many vision changes occur gradually, you may not realize your vision isn’t what it used to be. However, conditions such as retinal detachment can cause immediate, disruptive symptoms, like sudden flashes of light and vision loss, that you simply can’t ignore. These warning signs are serious and require comprehensive medical attention as soon as possible.

Even if you notice only slight changes, such as a decrease in your ability to read close-up or see other objects far away, schedule an appointment for a thorough eye exam. Early intervention can go a long way toward preserving your sight and overall eye health.
