Yes, comprehensive exams are necessary because many serious conditions (like glaucoma or early macular degeneration) develop without noticeable early symptoms
The automated photoscreener has a special camera which uses the red reflex which helps identify risk factors for decreased vision. The automated photoscreener is especially helpful in children ages 1 to 4 years old. The red reflex should be equal and the same in both eyes. Does every child who has a ‘failed vision screening’ need glasses? The short answer is no. Sometimes the automated machine over calls myopia and astigmatism in children. However—it is important to have a referral to an eye doctor who is comfortable evaluating children for a complete exam.
The first number is the distance in feet at which you stand from the chart, and the second number is the distance at which a person with normal sight can read the same line.
To reduce eye strain from digital devices, look at an object at least 20 feet away for 20 seconds every 20 minutes (if possible link to video library)
Prolonged screen time causes temporary digital eye strain, dryness, and fatigue, but it does not lead to permanent long-term vision loss.
Most people have experienced an episode of a twitching eyelid: either upper or lower or both. The twitch usually occurs suddenly and may last for just minutes or continue for days and rarely longer. It is annoying and may cause some anxiety, but is rarely associated with severe eye or neurological conditions. The most common causes of twitches are: stress, lack of sleep, stimulants (e.g. caffeine) and dry eyes.
A refraction is the test that is the starting point for your doctor to eventually determine if your symptoms; especially those regarding clarity of near and distance vision are simply due to a need for glasses or if they are the result of another condition or eye disease. This test does not hurt.
Cataracts should be removed when they begin to interfere with your daily activities or quality of life and your vision can no longer be adequately improved with glasses or contact lenses. The decision to proceed with surgery should be made together with your ophthalmologist, based on your visual needs, eye health, and readiness for surgery.
