Artificial Sweeteners & Your Vision

Posted by administration on July 28, 2015

Sweetners_and_Vision.jpgIf you’re trying to watch your weight by using artificial sweeteners instead of sugar, you may see an effect on your vision (which can be especially troublesome if you’ve already invested in better vision through San Francisco LASIK vision correction).

  • Certain artificial sweeteners, such as cyclamates, may make your eyes more sensitive to light (according to WebMD).
  • Blurred vision, eye pain and in extreme cases blindness can be a side-effect of sweeteners like aspartame.

Every person’s ability to handle artificial sweeteners is completely different. For some people, incorporating small amounts of these sugar substitutes will help in weight loss. However, others may be more susceptible to not only vision changes but other negative side-effects, including:

  • Weight gain
  • Mood swings
  • Headaches
  • Abdominal pain
  • Dizziness
  • And more

In fact, some nutritionists call artificial sweeteners “poison,” even though they have been cleared by the Food and Drug Administration. Not all sugar substitutes in foods are obvious; read labels to identify what you are consuming (aceslufame-K, sucralose, saccharin, aspartame, etc.).

Know your body. Know your vision. If you are experiencing any negative symptoms, contact your doctor to get checked out. You don’t want to put your health or your vision in jeopardy by the foods you are eating. And you don’t want to offset any strides you’ve made to achieve better vision.

If you’ve had to wear glasses for most of your life to correct blurry vision, and you’ve been thinking about having LASIK in San Francisco, Our doctors at Pacific Eye Specialists offers free LASIK Consultations.  Call (415) 921-7555 or to schedule your appointment today.

Are You a Good Candidate for LASIK?

Posted by administration on July 21, 2015

LASIK_Candidate.jpgIf you wear glasses or contact lenses to correct your vision, you may be wondering if LASIK in San Francisco could provide you with the clear vision you’ve always wanted.

The truth is, only an experienced ophthalmologist can determine if your eyes are healthy enough for this procedure. Even if you have the same vision prescription as a friend, your eye anatomy may not be suitable for LASIK. The doctors at Pacific Eye Specialists offers free, no-obligation, no-risk LASIK Consultations to identify all-laser LASIK candidates in San Francisco.

General Guidelines for Good LASIK Candidates

  • You have been diagnosed with myopia (nearsightedness), hyperopia (farsightedness) or astigmatism
  • You are age 18 or older
  • Your corneas are thick enough
  • You do not have eye disease or eye problems
  • Your vision prescription has been stable for at least one year
  • You are not pregnant or breastfeeding
  • You are overall healthy
  • You do not have uncontrolled dry eye syndrome
  • You understand the risks of LASIK
  • You have realistic expectations for the outcome of surgery
  • You want to reduce or eliminate the need for glasses or contacts

At Pacific Eye Specialists we also offer a free online LASIK Self-Evaluation to help people take the first step toward LASIK.

With our free services, there is never any pressure to have the procedure: the Consultation and Self-Evaluation are simply resources to provide you with solid information about your own eye health so you can make your own informed decision about LASIK.

Sometimes candidates who aren’t good candidates for LASIK can benefit from LASIK alternatives in San Francisco, such as photorefractive keratectomy (PRK). Different methods can produce the same end result as LASIK but be safer for certain patients.

To find out if LASIK is right for you, contact Pacific Eye Specialists today at 415-921-7555 or

Do You Need Reading Glasses or LASIK?

Posted by administration on July 14, 2015

Glasses_or_LASIK.jpgWhy is that restaurant menu so blurry?

The first step to answering that question is to identify when your blurred vision occurred. Have you had blurry vision for most of your life? Or is this a new condition that has popped up recently?

There could be many reasons why it may be hard to read things close-up:

  • Farsightedness
  • Presbyopia
  • Cataracts
  • Glaucoma
  • Or another type of eye disease

If you are farsighted, this means you have a refractive error (created by the shape of your eye or the curve of your cornea) that causes light to focus behind the retina, rather than directly on it. Farsighted individuals have trouble focusing on close-up objects. Refractive errors can be corrected through blade-free LASIK in San Francisco for many people.

As most people reach their 40s, a condition called presbyopia can make it difficult to focus on menus, smart phones and other near objects. Unlike a refractive error, presbyopia is caused by a gradual stiffening of the eye lens, making it harder to focus. Off-the-shelf reading glasses are available to help people combat this natural occurrence, but many dislike having to resort to “readers.” LASIK, in its traditional sense, will not correct presbyopia, but there are methods such as monovision LASIK that may help improve close-up vision. This method corrects only one eye for close-up vision while the other is left with clear distance vision.

Cataracts, glaucoma and other eye diseases cannot be corrected through San Francisco LASIK. Symptoms of these conditions may include blurry vision, so if you are experiencing any changes in your vision make sure to schedule an eye exam right away. Early detection can help monitor and protect your eye health.

Back to the original question: Why is that restaurant menu so blurry? The only way to find out is by scheduling an eye exam or LASIK Consultation.

Don’t leave your eye health a mystery. Contact Pacific Eye Specialists today to schedule a free LASIK Consultation and find out if your eyes are right for San Francisco LASIK. Call 415-921-7555 or visit to learn more.

Is LASIK Right for High Astigmatism?

Posted by administration on July 08, 2015

Astigmatism__LASIK.jpgAstigmatism exists when an irregularly shaped cornea or lens in the eye causes blurry vision.  High astigmatism is a more severe form, and cause reading problems, headaches and other difficulties. 

High astigmatism can be corrected with glasses, contacts or LASIK surgery.  As the degree to astigmatism gets higher, the choices in contact lenses gets slimmer.  Some people just don’t like wearing contact lenses or don’t find satisfactory improvement in their vision with toric lenses for astigmatism. Others may have eyes that are too small for surgery or contacts.

Each person needs to decide the right method for them.  Most patients with high astigmatisms try different options for correction before finding the one just right for them.  Eventually, many people get tired of dealing with glasses and contact lenses and turn to LASIK for their high astigmatism.

For extremely high astigmatism, LASIK may be a very suitable option. LASIK surgery attempts to permanently correct cornea abnormalities. High astigmatic patients will often see improvement in their vision, but may still need to wear contact lenses or glasses to achieve the desired results for vision correction. Although some patients may experience trouble with night vision and sensitivity to light after LASIK, the majority of patients do great.

Only your eye doctor can tell you if you’re a good candidate for LASIK.  The doctors at Pacific Eye Specialists in San Francisco are experts at LASIK surgery and will exam you to determine your suitability for LASIK corrective surgery. Give them a call.  They are happy to help.

Rubbing Your Eyes is a Bad Idea

Posted by administration on June 30, 2015

Rubbing Your Eyes

You’re tired. Your eyes are itchy. Naturally, you rub your eyes and they feel better. What’s wrong with that, right?

According to the staff at Pacific Eye Specialists in San Francisco, you can get dirt and germs in your eyes by rubbing them, leading to eye infections.

If you have progressive myopia, a form of short-sightedness caused when the eyeball is too long, rubbing your eye can worsen the condition.

Anyone suffering glaucoma should be aware that rubbing their eyes can lead to increased eye pressure, disturbing blood flow and leading to nerve damage and permanent harm to your sight. If you have had glaucoma surgery it is especially important that you avoid rubbing your eyes.

Those who have had LASIK surgery should also avoid eye rubbing for at least a short time, per the instructions sent home with you by your eye care professional.

If you have a condition called Keratoconus, eye rubbing can be especially dangerous. Keratoconus is a thinning of the central part of the cornea which results in the normally round shape of the cornea to become distorted and cone-like in shape.  Although it doesn’t cause total loss of sight, Keratoconus leads to a progressive loss of vision and can be severe enough for patients to be declared legally blind.
