How do I know if I need eyeglasses? Whether you currently wear eyeglasses or not, some of the common signs that you need corrective lenses or a new prescription include: Frequent headaches Squinting Leaning toward your workstation or using the zoom function on the computer Holding books, magazines, and mobile devices close to your face Sensitivity to light Eye strain symptoms You may struggle to see objects in the distance. For example, you might not be able to read street signs until you’re very close. As you age, the lens in your eye stiffens, and this impacts your ability to see objects that are close up. You might find that you have to hold your phone at arm's length to read your text message or that you peer over your glasses to read instead of looking through your corrective lenses. It is wise to remember that when vision changes are slow, we can slowly adjust to this slow change and not realize our vision is blurred. Often times it is after eyeglasses are dispensed that patients realize how bllurred their vision was prior to glasses. How often should I get new eyeglasses? There are two ways to answer this question. First, you can get new eyeglasses whenever you want. If you wear eyeglasses every day, you might want to have several different pairs of glasses to go with your clothing or you may want a pair of prescription sunglasses. However, the second point of view for this question is based on the validity of your corrective lens prescription. Corrective lens prescriptions are valid for a year, and if your vision changes between appointments, you should get new glasses with the correct prescription. However, if your prescription doesn’t change, you don’t have to purchase new glasses — unless, of course, you want a new pair of beautiful frames to update your look. Our eye doctor will advise you if your prescription has changed or that you may continue to wear the same prescription. How do I know which frames suit my face? Our experience

Glaucoma Q & A

What is glaucoma?

Glaucoma develops when your eyes don't drain efficiently, and extra fluid in your eyeball puts pressure on your optic nerve and damages it. The extra pressure and optic nerve damage eventually lead to blindness.

At idoc Optical, Dr. Rezvani diagnoses and treats both primary open angle and closed angle glaucoma.

Primary open angle glaucoma is the most common type of this eye disease. It develops when the drainage angles in your eye are blocked, and your eyes can't drain fluid efficiently. As a result, the extra fluid accumulates and builds pressure in your eye. Open-angle glaucoma usually develops slowly. It doesn’t cause noticeable symptoms in its early stages.

Closed-angle glaucoma develops when your iris is too close to your drainage angle and covers the drainage angle opening. This inhibits effective drainage and leads to fluid buildup in your eyes. Closed-angle glaucoma usually develops slowly, but the disease can also develop rapidly in an episode referred to as an acute attack. If you have an acute attack of closed-angle glaucoma, you may have suddenly blurry vision and eye pain.

What are the symptoms of glaucoma?

Glaucoma usually develops slowly and is sometimes called the “silent thief of sight” because it often doesn't cause symptoms until your vision is already damaged. The most effective way to diagnose and treat glaucoma before it permanently damages your sight is to have routine eye exams.

Signs of an acute attack or advanced stages of glaucoma include:

  • Severe pain in your eyes or forehead
  • Decreased or blurred vision
  • Blind spots in your peripheral vision
  • Seeing rainbows or halos
  • Nausea

You should make an appointment with Dr. Rezvani right away if you notice any of these symptoms.

What is the process for diagnosing glaucoma?

At idoc Optical, Dr. Rezvani uses a variety of tests to identify and diagnose glaucoma, including the tonometry test that measures the pressure in your eye with a puff of air.

Dr. Rezvani also uses a slit lamp to examine your eye structure, including your drainage angles and your optic nerve, for signs of damage. She also tests your peripheral vision for blind spots. If she diagnoses glaucoma or another eye disease such as cataracts, you’ll need to have more frequent exams so she can monitor your eye health more closely

What is the treatment for glaucoma?

Dr. Rezvani offers medical and surgical treatment for glaucoma. In most cases, she treats glaucoma with medicated eye drops to unblock and open your drainage angles. However, if you have severe or advanced glaucoma, Dr. Rezvani may recommend surgical procedures, such as trabeculoplasty and iridotomy, to widen and open your drainage angles.
