Keratoconus filters

Ways to filter out too much light

Filters can help people with keratoconus to be and stay active both indoors and outdoors. Vision loss isn’t the only symptom people with keratoconus experience. Also great photosensitivity or photophobia is what can hinder people with this corneal condition. The sensitivity to sunlight may lead people with keratoconus to avoid outdoor activities. But the great light sensitivity can also be very annoying indoors. Filters can help live, work and relax for keratoconus patients to do more business. Below you can read which keratoconus filters are (possible) available.

Workplace Lighting and Keratoconus

If a person with keratoconus suffers from light sensitivity and sits at a computer for long periods of time, fatigue may result. The light sensitivity is often not experienced as the problem, but the fatigue is. If your job or education requires you to read from a computer screen or mobile device for hours on a daily basis, this can also be very inconvenient for you.

How to filter light?

Below you can see how adjustments can be made in the workplace to filter out excess light:

• In a room with several workplaces, someone with keratoconus will benefit most from a workplace with walls from floor to ceiling all around. For example, the fluorescent light from the room cannot reach the employee’s workplace
• Filters in fluorescent light fixtures can greatly reduce the negative effects of lighting
• Try to create as much as possible in your own work environment where you can control the amount of light yourself

Which keratoconus filters are there?

For keratoconus patients with photophobia, using sunglasses on a sunny day while driving is sometimes crucial to driving safely. Even if you wear contact lenses or glasses to correct vision, light sensitivity can make driving difficult. Driving at night can be especially problematic because the headlights of oncoming traffic can temporarily blind you. If you have keratoconus, it’s important to know your limitations and adjust your lifestyle accordingly – especially when it comes to driving. Use – if possible – one of the following keratoconus filters:

• Polarized sunglasses: Whether or not combined with UV protection, polarized sunglasses can protect your eyes from harsh UV rays as well as reflected light rays that cause glare
• Contrast-enhancing lenses: these lenses allow the colors the eye perceives best to pass through and filter out colors the eye perceives less sharply. For example, blue is a color that the human eye perceives less sharply.
