Despite requests that patients bring their current glasses to their office visit, many show up without them.

Sometimes it’s an oversight: “I was rushing to get here and forgot them”; “I left them in the car”; “I picked up my wife’s glasses instead of mine by mistake.” Doctors have heard them all.

Sometimes it is unavoidable: “I lost them”; “They were stolen”; “I ran them over with the car”; “I left them on the roof of the car and drove away and now they are gone.”

Frequently, however, it’s intentional. There is a perception by some people that if they don’t like their current glasses or feel like they are not working well for them that they are better off having their eye doctor start from scratch. “Why would I want the doctor to utilize a pair of glasses I’m not happy with as a basis or starting point for my next pair of glasses?”

But bringing your glasses to an appointment is important.

There are two main reasons for eye care professionals to know what your last pair of glasses were.

The first is to see what type of glasses they are and how you see out of them. Are they just distance? Just reading? A bifocal? A trifocal? A progressive?

Even if you feel they aren’t working for you it is essential for doctors to know the type of lens you had previously. It is also important to know how you see out of them and what the previous prescription was. This can help eye care professionals determine a new prescription that will work better for you.

The second reason doctors like to know what was in your last pair of glasses is that the majority of people who wear eyeglasses have some degree of astigmatism in their eyeglass prescription.

A significant change in either the amount or axis of the astigmatism correction from one pair of glasses to the next is often not tolerated well, especially in adults. If you make too much change from the previous prescription many people experience a pulling sensation in their eyes when they wear the new glasses. It can cause symptoms of eye strain, headaches, and distortion, making flat objects like a table look like they are slanted.

Many of the problems that occur when we try to give someone a new eyeglass prescription could be avoided if doctors knew the last prescription and how you did with it.

Anytime you are going to the eye doctor, it is essential to bring your most current pair of glasses with you to the exam--whether you love them or hate them!

Christmas is one of the most joyful times of the year... thoughts of cookies, decorations, family gatherings, and toys abound. Birthday parties for kids add to the list of wonderful memories as well. But there are a few toys that may not make memories so fun because of their potential for ocular harm. The American Optometric Association lists dangerous toys each year to warn buyers of the potential harm to children’s eyes that could occur because of the particular design of that toy.

Here is a sample of that toy list:

• Laser toys and laser pointers, or laser sights on toy guns pose serious threat to the retina, which may result in thermal burns or holes in the retina that can leave permanent injury or blindness. The FDA’s Center for Devices and Radiological Health issues warnings on these devices at Christmas peak buying times.
• Any type of toy or teenage gun that shoots a projectile object. Even if the ammo is soft pellets, or soft tipped it can still pose a threat. Even soft tipped darts are included in this harmful toy list. A direct hit to the eye can be debilitating.
• Any toy that shoots a stream of water at high velocity can cause damage to the front and or back of the eye. The pressure itself, even though its just water, can damage small cells on the front and back of the eye.
• Any toy that shoots string out of an aerosol can can cause a chemical abrasion to the front of the eye, just as bad as getting a chemical sprayed into the eye.
• Toy fishing poles or toys with pointed edges or ends like swords, sabers or toy wands. Most injuries occur in children under 5 without adult supervision and horseplay can end up in a devastating eye injury from puncture.

The point is, that there are so many great toys to buy for children that can sidestep potential visual harm, that it behooves one to be aware of pitfalls of certain dangerous toy designs.

A great resource of information comes from World Against Toys Causing Harm.
