Since we are all trying to stay safe and healthy, we wanted to clarify a common misconception about vision and eye health.  People often think they do not need an eye check-up if they can see well enough.     Can you have good vision and still have an eye problem?  The answer is yes!  You can actually have perfect 20/20 central vision yet also have eye problems.  Here are just a few examples.

1)       Glaucoma, a painless optic nerve disease that is sometimes related to high eye pressure, does not necessarily affect your central vision until it is advanced.  This disorder causes patches of missing vision that are not obvious at first.   If caught early, glaucoma can be managed with eye drops or other treatments.

2)      Ocular hypertension is a disorder when the pressure inside the eye is too high and can lead to glaucoma.  While some people might notice headaches or changes in their vision, most people will not have any symptoms.  Intraocular pressure is checked at every eye exam as a screening test for glaucoma.

3)      A retinal detachment occurs when the nerve tissue inside the eye detaches from the back wall.   While symptoms can include flashes and/or floaters, it may not be noticed if this occurs in the far corners of the eye.  Treatment is required immediately to repair this condition.

4)      Blepharitis is an inflammation or infection of the eyelids caused by bacteria or allergies.  Some people notice redness, irritation, or itchiness while others do not have symptoms at all.  Treatment can include simple home care or prescription medications.

5)      Dry eye syndrome is quite common especially with the use of screens and devices nowadays. The reduction in oils and lubrication on the ocular surface can lead to visual fluctuations and long-term discomfort or pain.

6)      Cataracts, a cloudiness of the crystalline lens, can cause night problems, glare, and blurry vision. While usually part of the natural aging process of our eyes, cataracts can progress quickly if we don't take care of our eyes. Some medical conditions and medications can cause acceleration of cataracts. 

7)      Astigmatism is a condition that causes eye fatigue, fluctuations in vision, and computer vision syndrome.  This is fairly common and is corrected with glasses or contacts. 

8)     Binocular vision dysfunction (BVD) occurs when the eyes don't work well together or if there is a vision misalignment.  BVD can cause headaches, nausea, anxiety, dizziness, and reduced reading ability.  Glasses or vision therapy can help with this.

These are examples of eye conditions that can go unnoticed.  If you have a friend or family member who has not had an exam in a while or thinks their vison is "fine", please encourage them to have a check-up to ensure all is well.
