Understanding Presbyopia
Our bodies undergo many changes with the growing age, some of them are visible changes in the body due to the aging process.
One such change is the gradual loss of near vision, a condition known as presbyopia. Presbyopia is a natural and unavoidable part of the aging process. If you are over 40 and starting to notice that reading books, checking your phone, or doing close-up work is becoming more difficult, presbyopia might be the reason.
What Is Presbyopia?
Presbyopia is when the eye’s ability to focus on nearby objects diminishes over time. This typically starts affecting people around the age of 40, though the exact age can vary. Presbyopia occurs because of changes in muscle elasticity, unlike other refractive errors, where myopia or hyperopia mainly occurs due to curvature changes in the refractive surfaces of the eye.
Why Does Presbyopia Happen?
The lens of the eye is flexible, allowing it to change shape and adjust the focus so we can see objects clearly at different distances. As we get older, the muscles around the lens weaken, and it loses flexibility, making it harder to focus on things up close. You may begin to hold reading materials farther away or struggle to see small print clearly.
Common Symptoms of Presbyopia
Presbyopia can affect each person differently, but there are a few hallmark signs that indicate you might be experiencing it:
- Difficulty reading, you might find yourself holding reading material further away or straining to read text that you used to read easily.
- Eye strain or fatigue and discomfort, especially after reading or performing close-up tasks for a while.
- Text or objects held at arm’s length may appear blurry.
- Frequent changes in prescription
- Asthenopic symptoms: Straining your eyes to focus on near objects for extended periods can lead to headaches and other asthenopic symptoms.
Presbyopia and Technology
Today, many people use digital devices for reading, working, and socialising. The blue light emitted by smartphones, tablets, and computers has been a concern for some, though there is no direct evidence that it causes presbyopia. However, spending long hours in front of a screen can cause eye strain, which may worsen the symptoms of presbyopia.
How Is Presbyopia Diagnosed?
Your optometrist or ophthalmologist will check your vision both near and far by using certain tests that involve reading small print or focusing on objects at different distances. If you are 40 or above, regular eye exams are important to detect any changes in your vision.
Treatment
Presbyopia, a natural part of aging, cannot be prevented but can be managed effectively. Treatment depends on your preferences, lifestyle, and eye health and include:
- Glasses: Reading glasses or bifocal/multifocal glasses help with close-up tasks.
- Contact lenses: Multifocal contact lenses allow you to see clearly at both near and far distances.
- Surgery: Options like laser surgery or intraocular lenses can be implanted to restore near vision.
Lifestyle Changes and Tips
In addition to corrective lenses or surgery, some habits and lifestyle changes can help alleviate the symptoms of presbyopia:
- Proper lighting: Bright light can reduce the strain on your eyes.
- Regular breaks: Every 20 minutes, give your eyes a 20-second break by looking at something 20 feet away to reduce strain.
- Healthy diet: A nutrient-rich diet can be helpful.
