Drivers who fail the vision screening are referred to a vision specialist. Drivers with visual acuity of 20/200 or worse may not be licensed to drive. Drivers may use bioptic telescopes for driving, but may not use them to meet the vision standard". ...Read moreSee 1 more doctor answer
Stable Glaucoma. Recently thought could be peripheral vision Ioss driving. 3 recent field tests show no change. Dr.has no explaination. Am I paranoid?
Not paranoid: All with eye disease worry about losing sight. While most glaucoma can be managed with little or no loss, some do go out of control. Your ophthalmologist (you are not seeing an optometrist for this I hope?) did three fields with no loss. This is strong evidence of good control and you are on a good medication (Cosopt). Stick with this and express your fears to your doctor on next visit. ...Read more

Epiretinal membrane in 1 eye & cataracts in both. Are there any tests to determine which condition is likely causing glare & hazy vision when driving?
ERM & Cataracts: Epiretinal membranes (ERM) can affect central vision. A PAM (Potential Acuity Meter) can determine if it is just the cataract affecting general vision or the ERM. If ERM small, might still have 20/20 with PAM. Brightness acuity test (BAT): generally tells us how bad the cataract is. OCT (optical coherence tomography) tells us how significant ERM is. Frustration is in fact: still no guarantee which ...Read moreSee 1 more doctor answer

See your doctor soon. ...Read more
Vision problem only when driving. Bright LED lights appear to have a shaky ghost image right above it. ?
Don't drive: You should meet your state requirements for driving eligibility. There are telescopes built into lenses which can allow you to see better on a visual chart but these limit the peripheral vision which is critical for driving and they are dangerous. Consider the danger you place yourself and others if you try to drive with vision not meeting the standard. ...Read more
Mild muscle weakness: Most common explanation would be a slight misalignment of the eyes when tired. This kind of double vision should go away when you close either eye. Other possible causes would not go away when one eye is closed. A type of glasses lens called prism may be able to help this symptom. You should be seen by an eye md for diagnosis and treatment recommendations. ...Read moreSee 1 more doctor answer

Divergence palsy: When you look at a distance, the in-turning muscles relax, the out-turning muscles tighten. In your case, the out-turning muscles are week- could be medical side-effect, stroke effect, decompensated eye crossing, other neurologic disorder. If the amount of prisms becomes excessive, have eye muscle surgery. Contac a "pediatric" ophthalmologist who does a lot of muscle surgery. ...Read more
