Solutions to Common Optical Problems

Dr. Russel Lazarus, February 21, 2021

Have you received your new glasses, but there seems to be a few problems?

Your eye doctor will happily manage any issues, to ensure you enjoy the comfort and clear vision of your new glasses.

Eyeglasses are worn to correct refractive errors and provide clear and comfortable vision. Sometimes however, you may run into problems with your glasses that you may need to revisit your eye doctor to see if you just need more time to adjust to the new glasses, adjust the fit of frames or recheck the lenses.

Read on to find out if you can relate to any of these common optical problems and how to fix them.

Contact an eye doctor near you to discuss how to achieve the best vision possible.

My glasses are constantly sliding down my nose

If your glasses are constantly sliding down your nose, you may be feeling frustrated, irritated, or simply ready to toss your specs to the side and give up wearing them altogether.

Not only are sliding glasses extremely bothersome, they are also more likely to fall off your face and break— leading to further problems.

What causes glasses to slide down your nose?

  • Worn-out frames
  • Poor design match for your face shape
  • Lenses that are too heavy for their frame
  • Sweating

Plastic frames in particular tend to stretch out overtime, especially if you spend a lot of time outdoors in the heat, and even more so if your frames are already too large for your face.

What can you do?

Increasing temple support with a specialized headband or plastic temple supports can help prevent your glasses from sliding down. Adding nose pads can also help to keep your glasses in place for longer.

If your glasses are old and worn out or made with a delicate frame, they may require adjustments every so often— so it may just be time to bring them into your local optometrist’s office for an adjustment.

You may also want to think about purchasing a new pair of glasses— preferably with a light-weight frame that can be adjusted appropriately to your face.

My transition lenses don’t darken when I’m in the car

Transition lenses are lenses that darken when they are exposed to ultraviolet (UV) light.

Since car windows are known to filter out UV light, transition lenses may not always darken fully when sitting in the car. 

If you are looking for a pair of glasses that will protect your eyes from the sun’s bright light and glare, it is recommended to purchase a pair of sunglasses. Sunglasses are available in a variety of tints and colors and can provide the clear vision you need when driving.

Moreover, sunglasses can be made to include your optical prescription to ensure clear and comfortable vision while driving.

My glasses are causing a glare and making it difficult for me to drive at night. 

Glare can occur for a number of reasons. Before you blame your glasses, it is a good idea to have a comprehensive eye exam to rule out any other possibilities, such as cataracts or dry eye syndrome.

If your glasses are causing the glare, speak to your eye doctor about adding an anti-reflective coating to your lenses.

High index lenses which are thinner than regular lenses are also less likely to cause glare. Speak to your eye doctor to find out if you can benefit from high index lenses.

I am having a hard time adjusting to my new multifocal or bifocal glasses.

Bifocal and multifocal lenses can sometimes take a few days to several weeks to get used to.

Bifocals contain a bisecting line on the lens, known as a D-segment, that clearly indicates where each optical power is located and makes it easy to know where to focus for specific activities.

With advancements in technology, lenses are now being manufactured without the segmenting lines and can even be made with more than two optical powers, these are known as multifocals or progressive lenses.

Progressive lenses, as they are called, contain prescriptions for near, intermediate, and distance vision— without any obvious lines on the lenses.

The downside is, progressive lenses can take some time to adjust to. The mechanics of focusing through these lenses are a bit different when compared to lenses that contain a clear indication of where to focus for specific visual activities.

When it comes to progressive lenses, the bottom portion of the lens contains the near vision power, allowing you to see closer objects more clearly, while the top portion of the lens contains the distance power, allowing you to see distant objects clearly.

If you require intermediate vision correction for tasks such as using a computer or looking at the dashboard in your car, this area will be located in between the near and distance vision portions of the lens.

Learning how to use progressive lenses requires practice. However, rest assured that it will become easier with time, and your ability to automatically shift focus to different areas of the lens will become second nature.


If at any time you become frustrated during this adjustment period, know that you can always contact your eye doctor’s office. Your eye doctor will support you through this process.

If you are experiencing problems with your glasses, never hesitate to reach out to your eye doctor. 

Your eye doctor can make adjustments to your glasses or lenses to make them more comfortable for you, or may recommend purchasing a new pair.
