Q: Can I keep my old glasses and use them as a backup pair?
A: Absolutely. All eye doctors recommend that you have at least two pairs of glasses in case you break one. Using an old pair of glasses will not damage your eyes in any way. I always find using an old pair of glasses helps to make my house look cleaner.
Q: Why does squinting make your vision better?
A: The reason someone does not see well is because the eye is either too long, too short, or oval in shape. This misalignment causes a blur, or in technical terms, aberrations. By squinting your eyes, you are letting less light in and allowing less aberrations to take place. This allows you to see better, but the contrast is decreased.
Q: I turned 40 this year and my dad joked I would now needed bifocals. I see fine. Do I still need bifocals?
A: Around 40 we all start to lose some the elasticity of the lens in the eye to focus. This is due to several naturally accruing processes. When this happens your near vision begins to get worse. I have seen people as young as thirty need bifocals, and people as old as 60 without bifocals, but your dad is right, the majority of the time it is around 40. Happy Birthday.
Q: I was told I have a thin retina and if I see flashes of light or floaters to come in immediately to my eye doctor as I could go blind. How did I get a thin retina?
A: As the eye grows the tissue in the eye can be stretched causing the tissue to be thinner than normal. The stretch marks can tear without pain and cause loss of sight. This thinning is very common in people with high prescriptions (thick glasses).
Q: Why do I see little stars when I cough?
A: As the eye grows the tissue in the eye can be stretched causing the tissue to be thinner than normal. The stretch marks can tear without pain and cause loss of sight. This thinning is very common in people with high prescriptions (thick glasses).Coughing causes a lot of force on the head. Moving the head in a jarring motion, or squeezing the eyes shut can actually cause the retinal cells to fire off with a cough. This is of no concern as long as the “stars” dissipate immediately, do not occur without the cough, and you do not see an increase in floaters in your eyes. Any of these additional signs merits immediate attention.
Q: My vision went black for about a minute last week and then it came back. It scared me and wanted to know if anything could be wrong?
A: What you had is called a transient ischemic attack (TIA). This condition is not only sight threatening, but it is also life threatening. The two most common causes that are very dangerous is a clot in your carotid artery or a condition called temporal arteritis. Either way, you need to seek medical care immediately. Any sudden loss of sight that lasts a few seconds to a few minutes needs to be evaluated that day.
