Is My Eyesight Getting Worse: Uncovering Signs, Symptoms and Treatments

Eyesite Getting Worse: Uncovering the Symptoms

Vision is often described as the sense we value the most. If you’ve noticed a sudden change in your eyesight, it can be quite worrying. The positives, however, are that most common eye conditions can be treated. There are also several steps you can take to stop vision problems from getting worse as you age. To help, we’ve put together this guide to understanding the changes in eyesight to look out for, as well as ways that you can go about treating them.


What conditions can worsen vision?

There are many eye conditions that can affect your vision. Booking regular eye examinations with an optician is an important way of ensuring any potential problems are recognised as early as possible. Below is a brief overview of some common eye conditions, including the signs and symptoms that you should look out for between visits to the opticians.


Macular degeneration  

Commonly known as age-related macular degeneration (AMD), this affects the central part of the retina, called the macula, and is the UK’s leading cause of sight loss. If the macula becomes damaged it can affect your ability to see fine detail properly, and if untreated it gradually destroys your central vision. If you have any form of AMD, you may experience any of the following:

  • Blurring in the centre of your vision

  • Distortion of an object's shape, size or colour

  • Straight lines appearing wavy or fuzzy

  • Sensitivity to light

  • Seeing light, shapes and colours that aren't there

According to the Royal National Institute of Blind People (RNIB), antioxidants may help with some forms of condition.ii In some cases, anti-vascular endothelial growth factor (anti-VEGF) drugs are prescribed to patients to prevent vision from deteriorating any further.


Glaucoma  

While AMD can cause partial loss of vision, untreated glaucoma can cause more comprehensive vision loss. Glaucoma usually develops slowly over many years, with the main cause being a build-up of fluid within the front part of the eye, which damages to the optic nerve. However, because it first affects your peripheral vision, it can be more difficult to notice, particularly during the early stages.  Nonetheless, some people may still notice symptoms such as blurred vision and seeing rings or rainbow-coloured halos around bright lights. In a few cases, glaucoma can develop suddenly, causing symptoms such as severe eye pain, eye redness, headache and tenderness around the eyes.

Most cases of glaucoma can be treated with eye drops that help reduce the pressure in the affected eye or eyes. In some instances, it is possible to manage glaucoma through careful diet management and lifestyle changes. A few people will also require laser treatment or surgery to fully treat the condition.


Cataracts  

Cataracts are most commonly recognised through the clouding of the lens in your eye, which causes misty or blurry vision. They are a normal part of ageing, and most people start to develop cataracts after the age of 65.iii Similarly to some other eye conditions, cataracts usually develop slowly, which can make spotting the signs early quite difficult. As they progress, you may start to notice the following:

  • Sensitivity to light

  • Glare from bright sunlight or bright lights at night

  • Foggy vision

Since cataracts develop gradually, they too are often only picked up during a routine eye test. If your optician diagnoses a cataract in one or both of your eyes, the treatment is to surgically remove the cloudy lens and replace it with an artificial one.


Dry eye syndrome

If your eyes feel constantly scratchy and uncomfortable, you may have a problem with your tear film which could be causing dry eye syndrome. The good news is that while having dry eyes can be irritating, treatments are relatively straightforward. Speak to your GP or optometrist who can recommend a suitable eye drop to help make your eyes feel more comfortable. You could also introduce a humidifier if you’re in a centrally heated or air-conditioned environment. For more in-depth advice on how to manage dry eyes, see our guide to relieving the symptoms.


Steps to improving your eye health

Undergoing regular eye tests is the most important step you should take to keep your eyes healthy. However, there are other things you can do at home to maintain your vision and prevent an existing eye condition from potentially progressing.


Eat healthily  

A healthy balanced diet can help you manage your weight, which in turn reduces your risk of developing conditions such as high blood pressure, heart disease, stroke and type 2 diabetes – all of which can lead to vision problems. According to the RNIB, evidence also suggests that having a diet rich in fruit and vegetables may help keep your eyes healthy.3


Protect your eyes from the sun  

The sun’s UV rays can be harmful to your eyes and may increase your risk of developing AMD and cataracts. Look for sunglasses with a built-in UV filter – check that they carry the CE mark or British Standard BS EN ISO 12312-1.


Stop smoking  

According to the NHS, smoking has been linked with the development of AMD and cataracts.iv Indeed, the RNIB claims smoking doubles your chances of losing your sight, and can also make diabetes-related sight problems worse. If you need help with quitting, try using stop smoking aids such as nicotine patches, gum and lozenges.


Take natural supplements 

There are a number of nutritional supplements available that are designed to maintain and improve eye health, including certain types of antioxidants, omega-3 fatty acids found in fish oils, and vitamin D.
