In most cases, eye and vision problems occur so gradually you may not realize you are having difficulty seeing things far away or up close. That's because the brain is adept at adjusting to abnormal visual signals sent by the retina and optic nerve. Unless vision impairment happens rapidly, many people are surprised to learn they need glasses when they visit their optometrist for comprehensive eye care. To help you determine if your vision has changed, your eye doctor near Las Vegas provides an online vision screening you can complete at home.
This screening evaluates your near vision and distance vision while checking for signs of astigmatism, macular degeneration and color and contrast deficiencies. If you wear eyeglasses or contacts, remember to wear them during the screening. Also be aware that this online vision screening is for information purposes only and should not be used as a substitute for a full eye exam.
In addition to being simple and easy to complete, this online vision screening can indicate whether you need to see your optometrist for an eye exam. For example, you could have mild astigmatism, nearsightedness or farsightedness that will inevitably worsen without corrective lenses. If you are over 55, you could have early onset of macular degeneration, an eye disease affecting older people that impairs central vision but does not produce any other symptoms. Taking our online vision screening test could also suggest you have problems seeing objects clearly while your peripheral vision remains intact, a possible indication of age-related macular degeneration.
While online vision screenings are helpful for detecting refractive errors, it cannot diagnose eye diseases like glaucoma, diabetic retinopathy or other pathologies affecting your eye's internal structures. Drs. Kopolow and Girisgen urge everyone to make sure they get an annual eye exam that includes tests unrelated to visual acuity. For example, glaucoma increases fluid pressure in the eye but does not impact vision until it has progressed to an advanced stage. By this time, severe damage to the optic nerve due to glaucoma could lead to permanent partial or complete blindness.
