There’s More To Vision Than Just 20/20

When examining patients for glasses and contact lenses, being able to have those patients see clearly with the prescription is of course very important.  I recently prescribed a pair of glasses for a patient whose comment was, “I feel like my jaw is unclenching when I put these on.”  This is because the eyes did not work well together and when I prescribed a lens called “prism,” it helped the eyes to work better with each other.  In another case, I was doing vision training with a college football player.  His comment was “that everything looked as it was unfolding a lot more slowly implying that he was able to react to a situation on the field more quickly.


Making sure the patient receives a pair of glasses that takes care of the task is important.  So many patients older than 45 need bifocal lenses so they can see distance and near.  If they’re working a desktop computer with the screen at eye level as well at a different distance than their normal reading, could lead to a lot of neck, shoulder or eyestrain.  Usually a separate pair of glasses needs to prescribed for this situation. The same thing goes for an electrician who often times has to look at close up detail above his head.  In this case, we have to put a bifocal lens both below the center and above the center of straight away vision.  Even though these glasses don’t look pretty, for some patients who have this demand, they’re very functional.

Also, many times a child will have 20/20 vision at distance and near but still have a learning problem that’s visually related.  Sometimes glasses alone will help remedy the problem and sometimes you also need vision training.  This is sometimes overlooked by the practitioner.


These are just a few examples of  patients who may have 20/20 either with glasses or without who still may have vision problems.
